My wife was doing the dishes while I watched this. She said she loves his voice and could listen to him all day. Never said that about me. I was really beginning to like this channel.
Lmaoo
Sounds like something my lady would say. A sense of humor 👌 if it were me I'd say something like "just focus on the dishes" 🤣
Love the 3800 videos! Wish i knew someone who knew them like you man
About to do a firebird 3.8 rebuild, thanks for the guide!
my tip for using a torque angle guage: Mark the 0 degree position on the bolt before you start turning it. That way when you make a mistake with the gauge, you can use your mark to estimate the correct position which is much better than trying to guess how far you turned it before making the mistake.
This guy has the best damn voice for explaining things
You almost make me feel that I can reassemble a motor! Great video, thank you for taking the time.
Nicely done. The 3800 was one of my favorite builds.
How did the repair go friend?
A better way to dress the crank journals is to wrap the sand paper with oil completely around the journal..then use a string to put a half hitch or two around the sand paper. Pulling the string then back and forth will accomplish several things. Number one it will allow you to face 360 degrees of the journal, the string will keep a nice even pressure .. you will be surprised at how good of a job it will do.
Stars and stripes, eagle and made in China sticker, love it
God bless.....
Figures (sad but true).
nice job on the rebuild. i have a supercharged 3800 in my 2004 monte carlo I want to rebuild soon. I am surprised there is not many videos or information on these engines. that brown mud in the engine is dexcool antifreeze. i had a bunch of it in my engine when i first got it.
Yep switched mine over to antifreeze after changing dexkill yearly.
I Never use dexcool just good ol green
Thank you for this! The absolute best explained video I've yet to see on KZhead! And here I am watching every second, only to be changing upper and lower intake gaskets along with valve cover gaskets.
Dude your the most chill engine rebuiler I've seen " I'm gonna put it any away" lol awesome vid
1:24 looks like its from Dexicool that had a small amount of air in it causing it to react and create sludge. The color changes over time from not changing the coolant for years and can get like that. Ive never seen it that bad before though and dried out. Great video.
Братан, красавчик! В то время как много людей не знают даже как открыть капот, ты собираешь двигатель руками! Как бы я хотел жить в америке и иметь возможность купить автомобиль с таким двигателем..
Ce n' est pas réalisable avec Poutine,🥲
Nice job. I like those engines. Had one years ago in an old Monte Carlo
Thank you for the training! This video overview of this rebuild really helps, a lot.
I love you're video. Currently I have a coolant leak coming from this piece you are putting on at 16:05. One day I'll build something this cool out of my babygirl. I love her so much. Thanks for the video and reassurance.💪✊✊✊
Great explanation of the rebuild process! I have to admit, I could never get away with those dirty gasket surfaces not leaking. But if it works...
As soon as I saw you knock out that freeze plug I knew why it was clogged. I just commented on another video about that red GM antifreeze, it is terrible stuff that clogs and corrodes every engine it is put in. They claim it is good for up to 5 years but, if you have to use it, do a flush and fill at least every 2 years.
Thankfully my 3100 engine has a slow but persistent coolant leak. I just keep adding and I've never had the dreaded red coolant rust in mine. Have an '07 grand prix that's eating it though.
I say stick with the Dexcool. I use the Prestone version. All of the materials in the cooling system are designed around this coolant. If you keep it changed, it works very well. This engine looks like it was not well maintained.
ACDelco DexCool. A.K.A. DexKill/DexClog
My '04 Impala is still running well with no coolant leaks (19+ years so far). I keep a maintenance log in the car to track oil changes and other fluid changes. I change the coolant about every four years. Don't blame your lack of willingness to spend $25 on coolant and a few hours to change it on the product. Let's see...$25 vs $25K for a new car...no contest!!
It's orange, and it's called "Dexcool". If you purchase a car with this shit in it, do a coolant flush IMMEDIATELY and get it all out. Once your coolant system is flushed of all Dexcool, and is nothing but clean water, drain the system and refill with a good quality green coolant.
Change coolant n oils when due.My wagon at 850,000 ks.Still running nicely.Great job dude.
I feel confident I can do this job myself thanks alot
These are great engines. I've got the SC 3.8 in my GTP, dying to swap one into a Fiero GT, ton of engine for a 2600lb mid engine layout!
Good job, except I am using new rods and a rebuilt head. But that is just me. Enjoyed your skill and manual references. Too many people don't read the manual.
dude imma watch this video and rebuild a 3800 for my Bonneville SSEI ty !!
Great video...I HV a 2001 ss monte Carlo..I'm going to overhaul the motor .I HV no experience but thanks to your video ,I think I can do it...which me luck
Beam torque wrench! Love it!
Nothing more American than Stars and Stripes with an eagle and a sticker that reads made in china
Great video!!!!
Muchas gracias.. buena explicación
I’m gonna pull a Gen 3 3.1L out of my 99 Cutlass. It overheated really bad and it needs at least new rings and of course if all that’s being checked out it’s good to look at everything else in the engine for spec, including making sure the block has no cracks as well. It only has 70K so it’s less likely to have any bad issues minus the overheating risks. Should have done the wet compression test when I easily could have, knowing what I know now.
great video
Love this guy...
I Liké his Casuál Demeanor 😁😁👍👍
What was the fix for the excessive piston to wall clearance?
You need a tip button bro lol I have a quick question.. my plastic coolant elbow that goes into the intake manifold from the tensioner housing fell inside after I pushed it in to far and broke it trying to pull it back out.. the lip on the end of the elbow is keeping it from being pulled out can I reach it through the top of the manifold if I take the plastic plenum off
Hola amigo, sabrás cuál es el orden de encendido del Pontiac Bonneville 3.8 1998? Gracias friend
Watching the video with his such a chill voice put me to sleep 💤. I need this engine, transmission and power drive for my mom’s (deceased) 1982 Ford Granada.!! Would a 3800, Series 1, or 2 fit a Foxbody?
When putting the timing gears on. I see the first two gears have timing marks. After that the next 2 gears with timing chain get put on. Does the crank have to be in a certain position when you slide the 2 gears and chain on to time the crank to the cam?
When timing the cam to the cranck does cylinder 1 need to be top dead?
My mild custom 1998 Oldsmobile Intrigue (forever car) may need a new crankshaft as it spun a rod bearing which apparently let loose with the low-viscosity OEM recommended oil after hitting passing gear it sloshed like water it seems and the bearing went dry. I changed oil to Synthetic and STP synthetic oil treatment which practically silenced the knock- 3800 Series II loves synthetic oil. But what would go into changing the bottom end crankshaft, I already bought new rod bearings, could a repair shop on a lift R/R a crankshaft without pulling the engine? All I can find on KZhead or online is changing a crankshaft sensor.
replacing the bolts goes for all engines because of the heat and stress cause on them. yes they are a solid piece of metal but bolts are like springs and they stretch all the time any Machinist will tell you that
Back again, I finally have the engine back together. And of course it didn’t start, So I pulled up the codes. The only code that popped up was P0102 so I bought a brand new AC Delco MAF meter. Still nothing so I unplugged it and it started, so I plugged it back in and it dies. I’m pulling my hair out on this one, do you have any suggestions what it could be any additional advice would be appreciated.
What did you torque the intake manifold to? Thanks nice video
Pmsl this is the second air injection and this is some kind of manifold that operates it..its the bloody vacuum lines. Oh and when you said at the start when I was working on an ecotec this is an ecotec champ FYI
Could you provide me with the link of the repair parts kit for that engine bro?
After you resurfaced the Cylinder walls and put new pistons in, did the gap that was there fill; or was it still there? If it was still there how can a person fill the gap?
Hi, just wondering how the engine went after a few years after the rebuild. Like did the rear engine seal or sump gasket begin to leak?
How much torque did you add to the screws after installing the head screws?
When you resurfaced the cylinder wall, did it change the diameter of the walls or did it just smooth them up? also i am looking around for quality gasket kit, is DNJ good? are their gasket metal? best video i have seen on the the web by the way.
the cylinder walls are still standard size. Before this, I had no experience with DNJ stuff but it has been working with no problems so I guess they're good quality. I got that kit because it had things like the oil pan gasket and rear housing gasket and I couldn't find those anywhere else.
He never resurfaced them he just hoaned them its basically cleaning them no change is size.
my car was running fine no overheating missing or nothing. I heard a knocking noise in the upper part of the engine. i isolated the noise and went further to remove the outer valve cap and use a the test scope and heard the noise very loan on the 3rd rocker bolt from the left. After dismantling the upper part and removing the Roller Lifter i found it was damaged. Im in the process of removing the engine to remove and possibly replacing the camshaft. Did you get and part of your engine resurfaced? Do I need to resurface anything or just clean it up? How about the pistons? should I look to remove them and put new rings or just leave them and deal with the cam?
I didn't resurface anything on it and none of the gaskets have failed. If it's not burning a lot of oil, I would leave the rings alone.
where did you get the book from?
wait, hold the phone... the block was not sent out to be cleaned of all that gunk in the coolant passages, oil passages and the deck resurfaced since it was overheating? i'd also want to check the block for cracks and fractures - i know these engines are bullet-proof but i would not want to take a chance that the engine fails after 20k miles because i did not want to spend the extra money to have a machine shop go over the block.
Did you send the block out to get cleaned? I saw the mud where the freeze plugs were!
No I just cleaned it my self with a rod. Probably should have though.
@@onewhocollects6781 maybe .... - kzhead.info/sun/gdWwm9uhiaOMeGg/bejne.html
GREAT SERIES!!! Watching before I do the same thing to my motor, blew a rod bearing. How is that rebuild kit holding up
It's holding up good. That car is still being used daily with no problems.
Mud or dexcool ?
What about a 1989 buick 3.8 se-1 motor
I have a 3800 v6 series 3 engine i have to tear down. i have been searching for a manual on this engine for when im putting it back together. Any idea where i can get my hands on one?
Normally I get a Haynes repair manual for the car the engine is used in. I got most of the information for this engine from one. most of them have pretty good information on engine rebuilds.
Where did you get the tool that tells the degrees when torqueing the bolts?
Auto zone.
Great job, I have a quick question about the rocker arms. I see that you have the engine at tdc and I didn’t see how you may have adjusted them. Do you have to adjust the rocker arms or do you just torque them on?
There is no adjustment. you just torque them down.
@@onewhocollects6781 I got a question on the rockers aswell, i did head gaskets on my buddy's 3800 and when i torque the rockers down to spec on tdc it opens the valves when they are supposed to be closed and ideas???
@@jamessaxton4285 If Its at TDC between the exhaust and intake stroke, that could be normal. other than that I don't know.
@@onewhocollects6781 are you positive ? I’m doing a 97 Firebird I’m a little worried about valve lash ??
When you mix the green and orange
These engines were assembled with Torque to Yield bolts. They are designed for one time use only. Are you reusing them or did you obtain new replacements?
I figured I would have to, but the book didn't mention to replace any bolts other than the head bolts so I reused the rest. When I rebuilt my L61, I replaced almost every bolt in it because they were one time use.
What rebuild manual did you use for this? Great video too.
Where do you find the lower intake manifold? I tried finding one online for my 96 Camaro rs but I can’t
I just reused the old one.
How bad was it overheating, and for how long? Cracked heads and warped block could be the end of this engine.
I’m doing a rebuild on a 3100 and I really hope the block’s not cracked. Mine overheated pretty bad for maybe about 5 minutes total but more likely like 3 minutes. It’s been a good while.
Anyone interested I have 2 3800 2002 is naturally aspirated 9.4 to compression ratio. Also have dealer repair manuals 2000 SSEI supercharged. The 2002 is in a Grand Prix GT sport. 9.5 :1 compression ratio.Both vehicles are high end pontiacs with heads up displays etc
CR is listed in books for details.
I am interested
You selling the cars??? You selling engine/transmission???
How much to do mine!??
Is that madseason? Sounds just like him.
Both Pontiacs are complete. They ran well until sabataged by citrus residents
I need craftshaft bolts
hey i know you posted this awhile ago. but when putting the rockers back on, do you have to set lash? i blew up a motor and an reusing the heads from the olds
No. The adjustment is already built in.
@@onewhocollects6781 appreciate your response. i just torque and go then?
@@bksimplicity4329 Yep. that's it.
I checked with Hanes manual but they dont have a manual for my 2007 buick lucerne. From what I have been reading, the 2007 buick lacross uses the same 3800 v6 3.8 series 3 engine. Could I use this manual for my engine assembly being its the same engine? Im not concerned about the ins and out of the car in the manual just the engine. I have purchsed a pdf manual from another source but its dont go in debt on the re asembly
I guess It would work as long as its the same engine.
You can use a camaro manual even with a series 2 engine.
I'm a blessed man. I have a 1996 Oldsmobile Delta 88. It has a 3800 V6 Series 2. It has 153,000 actual miles. It runs smooth good but idles rough. Just a tad. I am thinking about giving it an overhaul. Am I considering this too soon? Car is rust free. It's in amazing shape.
I have a 3800 series 2 in my brother’s firebird that I’m currently fixing with exactly those miles on it too. It had cooling issues, but so far I’ve noticed it was leaking from the water pump and water outlet due to a cheap and badly done overhaul before we parked it for a few years (at the current mileage). The engine looks solid and runs so smooth, too so hearing positive comments motivates me to give it more love. Before we parked it, the “overhaul” it got was really just replacing all gaskets and a few components like the timing chain etc.
Is it worth just getting a whole new crate engine or too expensive?
You dont get what you want then
@@shadowopsairman1583 but you already have an anchor.you want a car that you can drive
Is it mud or dexcool lll mixed with rust to the point it's a solid?
Could be that too. I've heard some bad stories about dexcool.
DEXCOOL... horrible stuff. When I bought my two Monte Carlos (00,05) I flushed the engines and put in normal green Prestone..
@@richvolkjrful My Firebird 3.4l V6 runs on the green coolant
He should not be working on it anymore lol
It is DexCool, A.K.A. DexKill and DexClog.
How is the Monte Carlo with your rebuilt engine running these days?
It's still being driven daily. No new problems I'm glad to say.
@@onewhocollects6781 Obviously you know what you are doing. Good job. It is the best 3800 teardown and rebuild video on KZhead.
@@richvolkjrful Thank you!
It would have been cool if you showed cleaning the engine and parts :)
Sounds like Dex A Kill strikes again.
1:40 that aint Mud thats Rust
Your voice sounds like the guy on criminally listed
the guy that made any rude comments is a big meanie
My wife thinks its a wonderful video and wants to have someone like you rebuild our 3800 engine buick
3:33 wait for it.......
Itll be as good a rod knocker as any other.😅lol
Damn no circulation no cooling
Sure is shady under that tree...
I'm still skeptical about only 37 ft lbs.
37 is a starting point for the final torque in degrees you don't just do 37 and your done.
That's not mud it's block sealer or aluminum seal
Missing water pump impeller blades and a block full of red mud, "I have no idea how it got like that". Yes, you do. It's called DexCool and it's killed many engines I the last 3 decades. Switch back to classic green and that will never happen again.
You lost me when you said you would assume the crank journals were good without micing or plastigauging them.
SLOPPY MICKEY MOUSE
You have no idea what ur doing... Do you... You assume too much..
