How Come Timing Marks Don't Always Line Up Perfect?
Ever do a timing belt or chain and you go to line up the timing marks and find that they’re just a little bit off? This video has the answer to that question.
Also, if you ever wondered how many camshaft rotations it takes for the same tooth on a belt to come into contact with the same cam gear on a Honda D series engine, this is your video.

I timed my car 4 times with all the marks lined up, once i rotated the engine back it never lined back up, i was going insane. Thank you so much for this video. I can breathe a sigh of relief now. My family left me alone in the garage because i was yelling so loud to myself😂😂😂😂
This was me rite now until i seen this lol
It’s happening to me now 😂😂😂😂
Same.. LMFAO
I did the same removed belt 7 times so far 🤬🤬🤬
Hahaaa thats why i come here.
OUTSTANDING video, Eric! You are the only guy on YT who has addressed this issue, as far as I know!
Thanks Eric. I’m doing the belt now and was not sure why the marks weren’t lining up after rotating the crankshaft. You answered the issue perfectly.
Thanks dude, you've been here for me for the last 5 years. Learning how to fix my cars and helping troubleshoot problems. I couldn't have done most of the work without you and this channel. Thank you Eric.
Glad I could help. Thanks for the comment.
Excellent video Eric, I don't think I've seen any auto repair channel even discuss this topic. Thumbs up!
Reason number 14,973 why I love the internet. I'm putting a new timing chain on a 3.7 L Ford duratec, I couldn't figure out why the timing marks would point in the right direction every 4 Revolutions of the crank, but the timing marks on the Chain we're always way out of whack. I suspected it was something similar to hunting but now you have confirmed it. And you just saved me 5 hours of misery. I owe you a beer. Thank you!
It's always great to know when my work helps people. Thanks for the comment.
Great video and information! Was going crazy trying to line the timing marks up only to repeat this over and over again.
This was legitimately fascinating. Not even being sarcastic. Only you could take something trivial, and make a fun and informative educational video about it. *BRAVO!*
It explains my OCD worries and still having an engine that beat ass after a head gasket, water pump, and radiator; at different times in one month, and still breathing like a beast. It made me sketchy, about the work I had done, but after lifting the cylinder head, slapping it down twice, and revving harder than when I bought the car, I felt satisfied enough. All my worries on my first timing/head gasket job, over less than a tooth. Of course they won't say that in manuals, or most people online, liability reasons. Though, all the mechanics around me always told me not to sweat the small things like that here, it's nice hearing the logic behind it. Thanks again Eric! I would rather have a teacher like you than most others any day, keep at your approach and realism, I believe there are many that appreciate it.
Eric, thank you so much. 🙏 I'm an experienced home mechanic but almost had a nervous breakdown when glancing over at my phasers.
Thank you! I never usually mark the belt, just line up marks at TDC. On this 1.8t i did both and after rotating marks were off and I could not understand why. You have reasurred me!
Lol i did this once too for absolutely no reason. Can't remember it being that many revolutions though 😮 but pretty cool that you actually filmed it 😆 thanks Eric
You bring up a good point, Eric. I remember doing the timing job on a 2001 Camry V6, and customer had bought the timing belt kit himself. I recommended buying the Dayco or Gates timing kit, but he went with the dirt-cheapest option he could find (which always surprised me when he did that, because he was certainly well-off, but never understood the value of buying quality parts). Anyway, the marks on the timing belt would not line up with the cams and crank marks no matter what orientation I tried; so, frustrated and concerned, I had him go buy another new timing belt because I wasn't comfortable not knowing if the belt was spaced properly between the pulleys. Sure enough, with a Gates timing belt, it lined up perfectly. It could very well have been fine, as evidenced by your video, and knowing that now, I could have probably gotten away with it, but since I had never done one of those engines before, I wasn't going to take any chances and have to do it all over again!
sometimes those people are well off BECAUSE they are miserly. If you are always spending extra on everything, you tend to have a lot less overall especially if you are making modest income; but if that same person penny pinches everywhere, it can have a huge effect on savings and therefore you appear more well off (ofc your guy could be a millionaire, but to some extent it still applies ... but you did say a 01 camry, so probably not 'rich'). And to be clear, sometimes those cheap things ARE the same. Go to Wal-Mart. Look at Melitta coffee filters and then Great Value coffee filters. The only literal difference is the bag they are in and how much melitta cares about how centered that stack of filters are in the bag (they care very much, and the display cases, they need to be lined up straight too). I worked for a company that made them, the difference between runs was a bag switch and if the machine was slightly off, how finicky you had to be straightening them in the bag and keeping up with the machines. This company also made wet wipes, Clorox had their own line and product (they owned it) but the other lines for store and other brands were pretty much the same outside changes for 'natural' or brand specific scents (rare); and the hospital only line. The quality was all good, the company wasn't bad; just know that many products are a label or sometimes a container change, but can be the exact same product inside. If you ever wondered why something looked very similar or smelled pretty much the same, that is why. The products are basically contracted through other companies that focus on that industry. I worked for dayco at one point, they shipped hoses to a lot of places including actual manufacturers, not just your local parts store. If someone has that knowledge, they may just buy the cheap generic thing because they truly do believe it to be the same; and I guess he trusted your judgement and realized they could be different as well. That would be my attitude towards it except I usually do tons of research first, and hopefully if I found a mechanic that respected my efforts and willing to have a short conversation about the parts I want to get to put on the car, we wouldn't have one of Eric's other video's problems, the customer that buy bad/wrong parts and makes their life harder; that would never be my point, I just want to know what I put on and would like to purchase it. Like if I wanted Idemitsu oil in my car instead of generic 0w20 they get in bulk because it is proven to work in rotaries as it is what Mazda used at LeMans and in their race series to this day, it was developed specifically for the rotary and its use in being used in the combustion chamber to lubricate the seals and burn cleanly. (that is the type of research and detail I consider respectful to a mechanic that respects me, but what the hell do I know, I'm just passionate about the cars I own and want as much involvement as I can get, but I'm clumsy when I work on cars and usually hurt myself and sometimes the car, so I try not to do major stuff any longer so I don't break something (car or self!)).
@@kuromurasaki5273 You scratched the surface with this mindset, having capital allows you to be opportunistic with your investing. But this is a situation where you have to calculate if the upfront cost savings offsets the amount of time until the next belt change and the increased odds of the belt snapping and seizing up the engine. I would argue with the risk to reward ratio of purchasing a compentnet as important as a timing belt, you're much better off spending 100 dollars more to leave you that cushion for what if it does snap and costs you 4-5k towards an engine swap.
Hunting I think further confuses most , but I’m glad you explained and illustrated how long it takes before our marks will line up again. Excellent
Just finished a timing job on a 2005 ford f150 needed to hear this was scratching my head over this thanks Eric your awesome
Thanks so much! I'm rebuilding a Chevy 350 5.7L V8 and the timing marks are slightly off for the timing chain. Not too much. I'm glad I found your video. Now I can move on to the rest of my project because I would be here struggling forever to get it perfectly aligned. My rebuild book says it has to be exact but there's no way to get it right on each other.
This really threw me for a loop the first time I changed a OHC chain. I rotated the crank a couple of times to verify alignment, only to find the links WAY off. But the TDC marks showed that the crank and cams were still in sync, and that's all that matters.
So glad i came across this video. I was so scared I jumped a tooth or two.. Turned it a few times and couldnt get my marks to line up again and just gave up.. This gave me a bit of hope back.
Wow... very interesting, never heard about "hunting" before. Never told us that in tech school. Learn so much from Eric, thanks 🙏
I believe final drives are usually the same, and for the same reason. it spreads out any unevenness in wear - rather like rotating your tyres. :-)

Eric, hats off to you for having the time to do this workout. Over 50 times? I would give up after 5 times. I was so pissed off when I changed my first timing belt in one of my civics. I marked the old timing belt, moved the marks to the new belt to make sure everything was done correctly, and after rotating the engine, I never managed to get the marks aligned again. Guess what, I tool everything off, did it again, and the same thing happened. I just thought, possibly this is the way it is, god knows. Next day, me and my mate did it all over again, yes, 3 times in total, I just wanted to make sure I wasn't doing anything wrong before starting the engine for the first time after changing the timing belt. After the third time I just thought, screw it, I will start it, and it was ok. Now, before I attempted to change this timing belt, I watched some videos and so on, and I never came across about this so called " Chain or timing belt hunting" just after one year or so I came across another of your videos when you mentioned chain hunting, and I thought, bloody hell, this information is a bit late for me. It would avoid some phenomenal bad language used on the precess of changing this timing belt.
I feel your pain...took it 4 times on my panda
@@giogio4833 join the club 😀
I thought about that for a couple of minutes the first time I noticed, then I slapped my forehead for not understanding right away. Of course there is no specific limit of the belt length, it is as long as it needs to be to get around all the pulleys. The key to timing is that there are twice as many teeth on any camshaft pulley as on the crank pulley. The belt itself is only a passive participant, much like the road in a Nascar race. Even a small uniform stretch will affect the cam and crank pulleys equally, and timing stays in line! Manufacturers like to choose common lengths just so their parts dept can supply the same part to many engines. The mark will move around the perimeter of the belt path by exactly twice the number of crankshaft teeth every cycle, so the mark on the belt naturally creeps even without somebody planning it out. They aren't confined by the notion of keeping the belt length to pulley length to a specific ratio. The mark doesn't even have to return to home after a specific limit, though with the carefully designed notch spacing it will seem to do that because the length needs to be an exact multiple of one notch length (so that there are no gaps where the belt is joined end to end in the factory). As long as the pulley timing marks are aligned properly, the universe is in sync.
I've read a lot of fun comments about this video. This is fun too, but it's also the best explanation I've seen. Great comment. Good to see you Spelunkered.
it would be one very odd "short engine" to make it line up on the cam every other rotation even (belt would be exactly 2x diameter of the cam, lol) the longer the belt, the more rotations it takes to line back up at the cam and 2x that at the crank since cam runs half the rotational speed. rocket surgery =p
271 rotations to get the marks to line up again on a Subaru EJ25 (2.5L motor used in WRX/Sti and other Subaru models)! Eric should consider himself lucky that he didn't try this experiment on that motor! P.s. thanks for the explanation!
yeap, exactly. when we make some custom engines, theres actually a few different belts that will work on something like... lets say, a RB25/30 (rb30 SOHC block, with a RB25 DOHC head on it) , depending on where the new tensioner and idler pulley locations are, anything from a 250 to 255 tooth belt, usually we'll use a 253 tooth belt, just to have an easier time installing the belt, without too much slack
Your comment fully explained it best! Thanks! 😁👍
Yeah I remember way back when when I first did my Xterra 3.3 L timing belt same thing happened with me I couldn't figure out why the marks would not lined back up again turns out of course they are install marks only so the little white pen marks would never line backup but of course everything else did so little dimples drives you crazy sometimes thanks Eric
Thank you ETCG1. Good info. It help me to understand a lot more how does the system works. I appreciate.
Thanks for that. I'm having that same problem right now but I took the belt off like 3 times and recounted the teeth over and over!!! Thanks! Now I can relax.
OMG I've gone through the timing on this Nissan Sentra 5 x now trying to get it to line back up, bout to lose it. Thank you so much for this
Thank you for making this video. I just about had a heart attack when I did my timing. I did the exact same thing other people did. I aligned everything spun the crank around numerous times to make sure that the belt marks came back around. I literally thought that I had bent all of my valves, lol. No more paying attention to the belt marks for me.
I'm happy to help. Thanks for the comment.
Wow that was a crap ton of work for this one video. That explains when i was paranoid about the marks not lining up when i had to move the crank after taking the timing belt off. Internal combustion engines where never supposed to run perfectly. It is a miracle that they do considering all the varibles that go into them.
Awesome information Eric! I just timed my F-150 and was crapping my pants when i saw that the marks weren’t lining up!! Whew!
excellent video. this is why initial cam to crank timing is important. do that right an all is good. reusing old belt/chain? mark it to each gear, replace it to the exact marked locations. all is good. no worries
Im glad I saw this first lol, I was about to start rotating mine to make sure is align and was gonna take me a while to figure-out is miss-align
Always hated that and was scared that I was gonna mess something up thanks for the info ur the man!!!!
YOU SAVED ME ON A LATE NIGHT AT THE SHOP. THANKS MAN. ETCG1 ALL DAY.
Why would anyone thumbs down this vid? EXCELLENT INFO!
Eric very cool stuff man I was panicked about the links on the chain and timing dots not lining back up after timing the vehicle but the 2 cams and frank line up every second revolution
I have wondered about this for years but never really researched it, thanks.
Your a damn wizard you reading my thoughts I just changed a timing chain and was thinking about that I'll try on mine to thanks perfect timing 😉
Thanks for all the videos will definitely be watching the timing belt videos when I replace my timing belt on my civic
Thanks you I was so close to pulling the belt off again. I noticed my crank and cam gears we're in the right spot but the belt was way off. Short story thank you
This is awesome, thank you Eric, this addresses this question that was always in the back of my head. If machining is so fine nowadays that they can target tiny fractions of a mm precision, why are the marks off??? Now I know why
I've noticed if the heads been milled twice and or the block decked it can cause this. Half tooth off..great video
Thanks for this...just changed belt on my old panda and on flywheel marks seemed a couple of degrees out..tried to reseat belt 4 times.now I know why👍👍👍👍
Wow, All these years ,Never new. Thanks!
Hello I'm from England just got 1liter turbo honda civic with wet belt I've got to change it thanks for info Honda dealer recalled them back but don't won't nothing to do with calr saying don't worry I'm going to leave it and sort it out and look at you videos thanks and keep the good work up god bless have a good new year never give up we are all with you😊
Thanks for the heads up.
The perfectionist in me doesn't like it, but, it makes sense. Thanks, Eric!
The first time you realize this, you think something is drastically wrong with the work you did. I remember my first time. Good video.
Ive always wondered about this. I always thought it was a quality assurance issue. Now I know. Always best to hear it from Eric lol Btw, my profile picture are a set of k20a3 cam shafts and gears lol
That reminds me of the first time I did a cambelt, a twin cam at that, I added my own marks on the belt and pulleys, I wondered why they didn't all line up again soon when manually turning the crank.
Thank you for letting me know this I have an 06 Chrysler 300 and it was just a half a teeth off I was worry about it would mess up
It actually is my birthday thats weird that i just happened to watch your video. I love your. Videos i find them most informative
Happy Birthday!
@@ETCG1 thank you😄👍
I once had to remove the Bosch fuel pump on a Jungheinrich forklift with a Perkins diesel engine,took me about 35min to align all 5 marks on the gears(no belt,no chain,5 sprockets)
ONE DAY after my timing belt change on my 92 Acura integra GS! I was wondering the same thing 😁
Wooow.. I never knew that, it's nice to learn something new after so many years.. love your videos btw.. :)
How many licks to get to the center? Has now been answered!!!!!
THANK YOU!!!. sorry to shout but, that really helps me. I thought i would be ok but you splained that real good.
I’ve waited years to catch this on my actual birthday!!!
I just did a timing belt on a 3.0 accord, I noticed they didn't line up perfectly. I was hoping it was normal.
I knew they HUNTED, but never would have guess how many revolutions to get back home... enjoyed that .. Thank YOU
The manual for my B5 Passat had you make sure the crank and one cam sprocket (I think it was the exhaust) were both really close to the marks on the block/head, and then they should be completely "on the money" when you pulled the pin on the tensioner. I'm not even sure the belt itself came with timing marks, since they become useless as soon as you rotate the crank to check for proper operation.
Thanks man! I've always wondered about that!
Beautiful video. It seemed everything was fine despite the chain seeming a bit loose (changing it anyways, engine rebuild bc of overheating 70K mile car from ‘99). This vid shows that it’s probably fine that it’s slightly not perfectly lined up.
Very interesting thank you! So I have a job on a SOHC on my daily driver coming up where I’m changing the sprocket for the cam and the crank shaft gear because I’m pulling them out with the chain tensioner guide. My question is this I have a method to keep the new sprocket, cam, and crank gear, all identical when I place the chain, but do I need to make the chain timing marks match the sprocket and crank or will it be fine if the crank and cam are timed with the sprocket?
Makes sense for wear. Good topic. Thanks!
Good video, explains a lot, quick question, if my crank sproket timing mark is lined up with the arrow on the oil pump at TDC, and both my cam sprocket timing marks line up, how's come my crank pulley timing mark doesn't line up with my lower timing cover timing mark?
Interesting topic Eric. Unlike the old days of the chain in the Sb Chev where tooth count was the ratio, belts rely on gear diameter for ratio and tooth quantity is is developed with odd number. 🤔
Same thing, really - tooth count is a direct ratio to the gear's size, as the distance between teeth is set by the size of the chain links, so a specific tooth count would mean a set circumference for that sprocket. You can still count the teeth on the gears if you're using a belt instead of a chain. The biggest difference I see with belts is having a tensioner, which a lot of older engines (especially OHV) don't have. The tensioner lets the designers change the number of teeth in the belt a touch if needed by adding a tooth to the belt and designing the tensioner to take up just a little additional slack (as well as being needed because belts tend to stretch more readily.)
thanks for that , almost finished working on a bike , with that very same puzzle
This answered my question, what about those Honda odyssey V6 engine? Does both front camshaft marks have to line up perfectly to the marks on the timing marks? My rear camshaft was off a little bit but mine van is running fine after timing belt replacement job. Could it cause a p0420 code for a little off?
On DOHC Honda engines with 2 cam gears, there are timing marks on each cam sprocket that directly align with each other when at TDC. After I replaced my head gasket and had the head resurfaced, the timing marks were just every so slightly off from one another, 1-2 mm or so. I just went with it, and the engine has run just fine in the 35,000 miles since I did the work.
Mind BLOWN!!!!!
this saved my life just about to strip the motor down as I thought I had jumped the teeth , now makes sense why the mark on the chain disappeared but my sprockets remained in line
Hey man great video; I subscribed! I am at the timing part of assembling our 2004 Toyota Corolla 1.8 engine, following manual and advises from Toyota certified Mechanics from the dealer every one says it is not a big deal. We have been taking our time to put this engine together again, its been two months since I started getting it out of the car; I am not a car mechanic, this is my first time ever working in an engine at this magnitude and level and want to make sure the car not only will start once the engine is back in but that it would run too! now here is my scenario; Hynes book states exhaust sprocket (new) and VVTi sprocket's marks should be parallels to each other and in line with the timing chain cover, mines are like that, maybe the VVTi is a hair up; now down at the pulley I have the mark on it slightly to the left of the 0 mark; from right to left there is o mark, then a notch then a 10 on the timing cover; that I don't know what the other marks would tell me and I can not find that info anywhere; I just told the 0 reflects the TDC, yet there is some kind of "free play" (when I say free play, I do not see or feel anything worn out in the pulley or the crankshaft itself; crankshaft was polished the journals only at the shop but where the pulley goes was not touched so the pulley does not wiggles; in the timing gear parts everything is new except the VVTi Sprocket and its assembly) of the pulley in relation to the upper sprockets, like I can actually stay on top at the marks aligned then hitting the pulley by the 19 mm socket and breaker bar I can actually make it to get perfectly on the 0 position and then my VVTi sprocket is up by half a millimeter in relation to the exhaust sprocket mark next to it! Mechanics say this is fine, I am still nervous about it and have been thinking while the engine is on a stand, to undo the timing cover and try realign everything again????? My other concern was a slack of the chain (new) between the two top sprockets while I rotate it by hand, it is a slight dip but I thought that was an issue; two mechanics told me that is fine, in any case, another thing is the book tells you that the two top sprockets should be at 12 o clock position when installed; I tried this BUT the chain links marks where they fall on the top makes the two to be slightly off 12 oclock; the VVTi points 12:05 while the Exhaust leans 11:55! this throws me off because while sitting like that the marks on the side of the sprockets that meet next to each other are almost exactly aligned parallels to each other and in line with the edge of the timing cover as well! so seems there is no way to get it all to align perfectly! I WONDER keep wondering if I am fine or something needs fixing because my lack of experience? --- moving to a different "issue" I kind of concern myself with is with the head itself which was sent to a machine shop for prep and assembly; the valves were seated; the bucket lifts had been mixed out of positions by an Autozone "I know this" rep; I do not know exactly how they matched them again; the buckets have writings on them; I think he told me they grind the stem on the valve to "specs"; thing is the specs that are showing in a sticker on the car hood states the clearances for exhaust is 0.025 to 0.035 but in cylinder 1 I can not slide under the 0.025! the next one that goes barely in is the 0.023! ; would this be a problem????? That 0.025 feeler gauge does not goes under any of the buckets on the exhaust side; for clarification I am trying it with the elbows of the camshaft straight up. Everywhere else I have ok clearances the intake is from 0.015 to 0.025 and the 0.015 goes in each one of them, as well this gauge goes under the exhaust side ok but that is not the spec the manufacturer calls for so I don't know if this matters maybe this machine shop did not do a good job? Would I find out once the car starts?. I am a mechanic for ATM machines, in my field it is impossible to ignore tolerances without issues in the machine; less attention to detail techs do it all the time on the field and invariable sooner or later there are repeated service calls and difficulty to diagnose an issue and it always rest in a tolerance that was overlooked; this is why I am so concerned here; my own lack of experience and "don't know how" is killing me, lol. But I have to deal with it and do it because I can not afford the street mechanic and less than less the dealer with this big engine overhaul; the price exceeds the value of the car!
Now it all makes sense. I always kind of wondered why they were a little bit off. It made my brain hurt when it wasn't perfect. Engineering at its finest.
Super patient to do!
Wouww. Everybody just shows how to rotate the pulleys but you are explaining what we should expect and why we should not surprise if we cannot align at the first place. Now it makes sense. The question is when should we align the timing belt?)I mean I want to change only tensioner. I am planning to use old timing belt. Do I have to still align it?
perfect! thank you, eric
Thanks, I did not know about that. I wanted to check my timing belt on my Mitsubishi Lancer but i was so unsure about getting the timing correct that i took it to a mechanic shop to have it checked. Turns out it would have cost a lot less if i just did it myself. Thanks for making the video. If you can can you make a video on the timing belt replacement on a double cam engine japan made vehicle.?
Thank you for the video I have a 5cyl. Volvo I need to do a head gasket on soon. Have you ever heard of early 2000s Kia's having ignition lock problems I'm working on over that's been sitting for a long time, I put a battery in and I can't get the key to turn more than one click thank you in advance I love your videos plus you look just like my best friend lol
Holy crap Eric, bet that was a workout...
Heck yeah! He should show off his guns afterwards. Kidding. Lol
he had the plugs out i think
@@360fanboy360 smarter not harder, right? Lol
Eric, I think you're a bit confused on why the belt or chain hunts. The sprockets teeth are not offset, they are symmetrical. Having them asymmetrical would be diffcult to time and correctly align and require a keyed belt or chain and cause problems especially Piston to valve or valve to valve contact on interference engines. The belt or chain itself will always hunt because the difference in sprocket sizes and number of teeth on belt or chain. *large cam sprockets, small crank sprocket* The difference in these sizes make it appear the belt or chain has shifted or is hunting but not really, it's due to turn ratios in cam to crank, I beleive it's 1 complete revolution of crank for every quarter turn of the cam on the 4 bangers. The belt in your case took 52 revolutions of the cam due to the number of teeth on the belt, if that is a d16 engine, it will use 104 tooth timing belt (go find the old belt and count, I bet I'm right), divide that by 2 and you get 52. That's how many times that belt has to go around the cam before it lines up again. Even though every 4 revolutions of the crank makes one complete revolution of the cam itself. The TDC marks on cam and crank will always line up when cylinder 1 is TDC, always! That's why shop manuals tell you to rotate engine several times by hand and verify the forged alignment marks and ensure that nothing odd is happening with the tensioners or slack guides causing it to go out of time. Which is why it's recommended to bring the engine to TDC before you do a belt or chain replacement.
Absolutely correct. I would add that the reason timing Mark's dont always line up is due to a combination of initial manufacturing tolerance, cylinder head gasket compression (which affects the distance between pulleys, cylinder head re surfacing (which reduces the distance between pulleys and belt stretch. Additionally there is a measurable change in distance between pulleys when tbe engine is hot. Thermal expansion is a notable effect.
Shade Tree Mechanic Pro Tip: If doing a timing belt with a mechanical (or spring with a jamb nut) tensioner, and the timing marks seems slightly off, check if the belt tension is set correctly. I was doing a timing belt job on my Nissan 300ZX and I noticed that the timing marks didn't exactly line up. I started turning the engine over by hand and the belt got sloppy either between the crank and a cam gear, or between both cam gears. Retensioning the belt fixed that.
Finally! It IS my birthday! Thanks Eric
Happy Birthday!
I have a 2005 mitsu eclipse 2.4 with the timing belt . Looks like the timing on the oil pump gear is off 1 tooth could that make the oil can light on an off on the dashboard ? It starts runs an idles fine . Except it did develop a knock an 1 set of rod bearings needs changing . Wonder if it being a tooth off could throw the oil light an cause the bearing to go bad or would the oil pump gone bad all together ??? Any help please 🥺 !!
Cool topic! Ah Honda, anti-clockwise rotation..
My thoughts too .i never rotate my engs in the opposite direction from normal rotation .not sure if it matters just something i dont do
Yep. Can't use the time-tested starter trick to break that crank bolt loose. Honda should have made them left-hand thread.
@@derekholdt747 question. Is a normal bolt, left or right hand threaded?
Only older honda rotate this side

Years ago, my shop "mentor" explained this to me, but I had neither the apptitude nor capacity to understand. 22 years later, Eric explains it, and it's like: oh yeah, duh. That makes sense.
On my 72 2.0 My timing belt is on right I think " Compared it with my 73 - but my timing light shows it's off by like an inch on the 72, Car won't run if I put at 6 before TDC. Could the Distributor be why it's not lining up right with the light strobe. The 73 strobes the light spot on 6 before TDC
Learned something new today, thanks
Thanks for the info, just out of curiosity does it matter if you turn the crank clockwise or go counter clockwise?!?
very interesting, I never thought about it...I guess it's made to hunt over and over to distribute equally the wear and tear of the belt or chain evenly. That's efficient engineering.
Is this the same set up for a Mazda protege 323 2000 model i went to loosen the screw on one of the sprocket the left hand sprocket timing Mark move do I need to put the belt back to reset the timing marks?
cool I never knew that...... Thanks Eric....
Thanks. As a weekend idiot I've done about a dozen timing belts on my cars and have always agonized over those marks not being precise.
Hey eric got a question. I replaced a timing chain gears and tensioner on 09 dodge avenger 2.7 and as im rotating the engine i noticed that the tensioner and guide seem to slap. Almost like the tension doesnt full extensend to keep chain tight. Thought maybe tensioner was bad. Bought another new and same thing. Each rotation i go to make sure the marks line back up which they dont now after i seen your video im going to try the 52 rotation or so to see. But the tensioner guide is more of my concern? How do i fix that
I work flat rate World as you know how that goes, never really noticed but I don’t mark new belt. When checking I’m more concerned that cams are lined up with crank before putting back together.
Wow holy cow.. thank you brother! :) Love peace and axle grease
Hey Eric............awesome info AS EVER , man you are the BOSS !.........
I have an question for you, I set an timing belt and the mark for the 2 top dead centers keep hitting dead on but no matter what I do the crank saft mark keeps landing slightly left of zero tried resetting it 3 times. It's on the 1990 3vze Toyota engine?
Eric, if my 360 jumped a tooth or 2 how do I make sure it is aligned when I replace the parts?
Hi Eric, I’m installing my timing best now and the 2 solid lines match up with the tdc marks for the camshaft pulleys but the dotted line is a few teeth off for the crankshaft. Should I be concerned? Should I line up the crankshaft line and not worry about the camshaft marks?(this is what I’m thinking is the point you’re making in this video but I want to double check) thanks!
Hi there plz can you help me out I try test that website you said I will answer but is not work so I have now 2012 Ford Focus se I change Head gasket my self but won’t star the car now and I forget to pot marks on the timing chain plz tell me how I’m going to do it how going to link up
Good video thank you! So I was setting the timing on 2009 dodge ram 5.7L and it lined up correctly and I released the tensioner but I rotated the crank 1 more time and it didn't line up, so???
I have an automotive question. If I am replacing tires and aligning the wheels at two different locations, does it matter which of those I do first? Are there pros and cons to doing one or the other first? Does it not matter either way? What's your take on alignment first or new tires first?
