S62 M5 V8 Engine with 392,000 Miles Full Teardown
Episode 2 On the Tyspeed KZhead Channel brings you a full long-form and intricate teardown of BMW's Almighty V8 - The S62 ! PetrolHead Studios was in the house to film this epic teardown of one of BMW's Best V8 engines!
The BMW S62 engine (full model code S62B50) is the high-performance variant of the M62, which is fitted to the E39 M5 and the E52 Z8. The S62 was BMW's first V8 engine to have double-VANOS (variable valve timing on the intake and exhaust camshafts).
The S62 engine produces 394 hp at 6600 rpm and 369 lb⋅ft of Torque at 3800 rpm. The redline is 7000 rpm. The bore and stroke are 94 mm (3.7 in) and 89 mm (3.5 in) respectively. This results in a displacement of 4,941 cc (301.5 cu in)
Despite some suspected damage of a few common parts , this engine was in surprisingly great condition for its age and mileage, minus some really crazy leaks!
This is part one of two . Stay tuned for the rebuild episode!

Engine Rebuild: • 392,000 mile S62 M5 Mo...
Some of your info on the block is slightly incorrect; the bores are in fact not coated or plated at all. The block is cast from Alusil which is an aluminum silicon alloy and is compleatly linerless. They can definitely be re-machined and overbored but a specialized honing process must be used to expose the silicon crystals on the surface.
Yes, You are right- its hard to speak on the cuff , with no script!! This is our first video like this and I will make improvements going forward to be more specifically correct with the information we are providing within the video. I hope you found the video/editing to be somewhat entertaining despite this factual inconsistency! And yes- while we can do rehone this- we are electing to have VAC sleeve it! Thanks for commenting.
U sure know ur stuff. Gj
@@tyspeed24 just need to get that camera focusing correctly...its jumping alot between face and far our background. Shouldn't be doing that if its on facial. Or the camera man must just pay attention to the focus Zebras.
@@VegManLife No he is not. Any machine shop can properly re-produce the alusil surface with a special compound, special hone, and a surface profilometer. You can literally find the whole tech briefing PDF from the company who invented AluSil. It outlines the exact process. There is no special trick or mystery, and everyone claims “their guy” is the only one who can do it. I’ve personally spoken to 5 or 6 shops here in the west that said they’d do it no problem. Due to the cost, extra steps, and how rarely the process is needed, most shops still recommend iron sleeving or nickel plating the cylinders, as it’s easier and lasts longer. It’s not that it can’t be done or that it’s hard to refinish an alusil block, it just makes no practical sense to do so.
Yes. This is the correct way. Boring and sleeving is a hack that’ll create issues down the road.
As someone who knows very little about engines I really appreciate that you took the time to explain every step.
But the government has not yet decided whether
No one should be surprised. If it's well maintained. Any engine will last. 😊
From a person with no interest in rebuilding an S62, I watched the entire video. Great content. Great narration. Awesome to see your work being done in this throw away society. You’ll have a place well into the future as a premier technician providing quality workmanship that won’t be replicated by many. Can’t wait to see this engine running again.
Time to buy an M5
Such a satisfying video with great insight into your process, passion and attention to detail. Loved watching this and I hope see more.
Great video Ty. Informative, interesting, and well edited. I love stuff like this. This is TV quality.
Im a laymen but m539 restoration had issues with a sleeve in a alpina v8. Machining might not have been great but realized there was design flaws with alpina aluminum pistons expanding at different rates than factory block which makes them all eventually wear out prematurely. The iron sleeves just accelerated the flaw x1000 faster iirk
Didnt Sreten have a bad slevejob. When he went to a specialist to check the bore i think taht the cylinders were warped a little. Afaik you can sleve the block it just has to ve done correctly
Please do more of these videos! They are fantastic to watch
We’re on it ! Thank you
Amazing and informative as always!!! Keep it coming!
Great video, feel like I found an awesome new channel, really looking forward to more videos like this. Super informative and well put together.
Great video Ty. Looking forward to what this channel has in store!
Very nice video and very informative, thx and keep up the good work.
Great informative video, a real professional. Good work!
Love a good engine tear down and build series, especially old BMW’s. Subscribed.
Amazing video Ty, keep this up for you and for us sir!
Wow I just subbed… this channel is what we needed all this time
this amazing to watch, nice craft knowledge and skill. flipping impressive. i know engines a little rebuilding bikes n things but to actually know and understand the engineering and everything else engines have going on is super deep. you must be very passionate 💪
Awesome man! Very informative, can’t wait to see you put it back together with a supercharger that thing so going to pack a serious punch!
So happy to see people keeping these cars alive. Truly the muscle cars/classic cars my my generation
Respect ! nothing else to say from a mechanic and can't wait to see this beauty turned
So much knowledge! That's crazy
Awesome video, I really hope you make more videos like this :)
Great stuff, very thorough
learnt a lot from this video. wish you could vlog more often on your shop. we know you got a business first but it would be cool.
Great video, interesting to see the process
Perfect editing and presentation, looking forward to see what's next.
Much appreciated!
Wonderful video, incredible detail and narration. I'd love to see a high mileage S65 teardown next!
I actually have one that has low compression, we plan to do next !
It’ll just have scored cylinders, and then it will be junk or it will need sleeves. That’s how just about every S65 goes these days, if the rod-bearings or main bearings don’t get it first.
Thanks for taking the time to film/edit/share this video. Well done! 👍
Glad you enjoyed it!
hey amn, i love how you teach , im from south africa and you have helped us so much with our current s62 rebuild we have,!
Amazing . Glad I can help ! We’ll be doing one with the rebuild soon
Chain guide tentioner failing does happen, I agree, it's not that common on a well serviced engine however. Changed my rod bearings and the full timing chain/guide kit on mine, not a 392000 mile engine tho, somehever close to half that milage and the guides did not have a singel piece missing and basically no wear on them, what so ever nor were they fragile. Rod bearings according to the engine builder was good for the same milage again. Taken care of and driven carefully when cold theses are sturdy engines. Great video however, very informative.
I just bought a 200,000 mile 535i wagon that is in fantastic condition. A lot of the service records were from Tyspeed. Now I understand why it is in such great shape for 200K! Keep it up guys!
This is dope!
Great video!
Bought an e39 535 about a month ago. I absolutely adore the car but I’m currently getting it serviced and it’s gonna cost me about 2k to get it perfect. Not to mention I’ll eventually have to do the vanos rebuild and timing chain guides. I got the car for cheap though so the maintenance is no problem for me plus the car is just an absolute dream to drive so well worth it.
great work
Great video! I'd love to see an N55 build or S63!
Great video. Very informative. I own a 2014 F10 M5 with 57K miles.
Damn this channel will blow up the editing was perfect.
Much appreciated! Very excited for the opportunity to follow Tyler’s journey. There’s a lot of cool stuff coming to this channel.
Great job... From Argentina... Keep it up....
Former Lexus tech here: sweet baby Jesus thats such a complex engine design. Definitely got lucky that the Toyora/Lexus VVT-i was comparatively much simpler and robust. That said, you definitely know your stuff and its clear your definitely earn your paycheck. Good stuff.
Tyler and Team at TySpeed are great! Knowledgeable, professional and very client focused. I brought my E60 545i there for awhile until I got rid of it. Their work is top notch 👍
How long do you want the intro? TYSPEED : Yes
🤣It is our first video after alll...well trim it down .
Excellent. Not being mechanically inclined myself, I'm always impressed with the skill and knowledge needed to tear down and rebuild these modern engines. Well done. The only small issue I have with this video is the audio. It might just be me, but with all the volumes turned up to 11, some of your words would still taper off and be difficult to hear. If no one else is having this problem, it might just be on my end. Anyway, great video!
Right on ! Thank you 🙏
Cool video, s62 is an impressive motor, a built one will be amazing.
Cool video! I didn't know HOW complicated those beasts are! Nice music too. (What band?)
Nicely done! I thought I was doing something when I did my TCGs by myself in my garage on my m62 (non vanos) 435,xxx mile e38..
There's the key for reliability, non-Vanos, for what an extra 15hp!! 🤣
Be careful with the sleeves. They will not dissipate heat very well. The original block can be re-machined however there is a special process to re-expose the crystals in order for proper oiling. Talk to partee racing, they do it often.
I know David, and will certainly get his .02C . We've used VAC before in a few instances for rebuilds like this and have had success; If you have more information you'd care to share I am all ears. Id be interested to know if you have specific instances of failure I should be aware of , etc. Thank you!
M539 Restorations did the same thing on Alpina block and blew up shortly after. Very courious about the sleeve, definitely subscribed
@@ilfordino-fordfiestatutori8725 I think the main issue was a machining error where the cylinder walls were out of spec
@@tyspeed24I have a block with iron sleeves made for a compressor. It has been driving for almost 6 years without any problems, but you need to be aware that iron releases heat slower - avoid constant heavy load.
Great video, well presented
Glad you liked it!
Your passion is evident. Love the videos, keep em coming! That s62 is in good hands
Excellent explanation of the Motor & what your doing & how the Motor Works…Straight to the Point-Cut & Dried…No BS🦾
Hello TYSPEED, Please add follow-up videos. Alusil block can be bored to 0.2mm over if pistons available. I am working on S85's and have sleeved two and trying to get another oversized in original Alusil lining. On your Iron sleeves, what rings did you use? Thank you for your video P-Chi
Are there metal replacement parts for those brittle plastic pieces? Also wanted to say that this is a phenomenal video. I love the detail and explanation you've put into everything.
Well, those brittle plastic pieces held out for 392000 Miles…..
Very satisfying teardown! Amazing to see forged pistons last this long. When you rebuild, will you go to 2618 or 4032 alloy? Looks like most people like 2618, if you go this way how much life do you expect out of them? I also enjoyed seeing your RC airplane collection the background.
I enjoyed the video and gave you a thumbs up, I would say that bore material looks like Alusil to me, it is machinable but only by specialists, the issue is that the pistons require a special coating to run in that bore are often unavailable or very very expensive and not necessarily that good for performance. I agree you cannot machine the Nicasil bores but only deglazing is possible however you can send them out to various coating places like Milenium Technologies. I’m with you that the sleeves should offer the best long term solution.
Thank s for this vid. Wondering however why you didn't power wash before teardown or even in the car before pulling?
That e34 on the background.... 🤤Cheezus....😍 Nice video Though! 😎
Nice video. I love watching these while eating my supper
Glad you enjoyed
This motor tear down is really complicated. Reassembling use be even harder. Great to see young techs so knowledgeable.
As a BMW specialist, surprised you don't know how to recondition a Alusil block. Sleeves for these S62 blocks are in general not a good idea. PS: if you have the head or block deck machined, be sure to have the timing chain covers (all 3parts as appropriate) or you will need a thicker head gasket to make up the material removed.
Hey, Thank you. Yes for sure, we are using the additional thickness gaskets for this as yes, both the block and heads are being machined! Separately, while I have heard many things about the sleeving, I have yet to experience a real world example myself. I'd be curious to know, (and please feel free to share here!) Specific ways that you have experienced failure of sleeved or remachined blocks . This video was made educationally- and I certainly do not claim to know EVERYTHING out there. How many even good BMW techs often tear down an S62 with 390K Miles in their career? Certainly an outlier of a scenario. Please feel free to share any relevant info and If I can, I will include in the next video. Thank you !
@@tyspeed24 Take a look at M539 Restorations here on YT ; Take a look at the Alpina restoration (early engine rebuild with re-sleeved engine); now, to be fair , it looks like the machine shop he selected was not competent and the engine soon failed (piston slap in under 100miles)! Evidently, setting up the bore tolerances is quite challenging (?????). At the very least, when you get the block back, be sure to check the cylinder bore specs/tolerances, two or three times!! As you will see in his video(s), he did not check and the follow up video with another machinist showed tolerances way, way to tight. I think it would be worth your time to get in touch with Srenten (check spelling) and have a chat ; he has many European friends who are well aware of the problem and have a work around as well (also shown in the second engine rebuild video).
I enjoyed the video very much, it is however VERY low volume overall. Good stuff none the less!
Awesome video, love to see more high milage S62s. Any ballpark on what a full teardown and rebuild would cost? *stares at 314000km S62*
I am interested in a ballpark number as well.
+1, 235k miles here
Me too! 317000km and running
Hello, Great video. I have a E39 540i. Would like to know where did buy the complete pistons for your car. Thanks
Hahaha I'm from Jackson originally. Awesome to see this
There are shops that do brank new Nikasil coatings on bored-out cylinders, have you tried that in the past?
hiI!, Great video, like the comment before, I replated my cylinders(honda cbr1000rr), I choose to use nikasil over alusil. cylinder plating has a lot advantages over iron sleeves.
2000 E39 M5 owner here, 235,000 miles, one major repair back in '08 for a burned valve, no major engine work since...BUT...what does an S62 rebuild typically cost? I want to keep this car, but she's a nearly daily driver. Will keep watching, I get a lot of the expense of rebuilding one of these things now...
Nice R/C planes !
What does a complete teardown/rebuild look like from a price perspective on this motor? I have an '02 that is recieveing new chain/guides along with new valve covers. The car has 140k miles and I want to rebuild to new. Thanks!
holy shit an oxford green E46 M3 in the background. Rare AF.
It’s for sale !
Thanks for the upload. Questions: Does machining the head and block surface change the distance between the crank and the cam? Will it effect timing? Is there a way to compensate for that?
The way you compensate for that head gasket thickness. You can also change the depth of the Combustion chamber part of the head etc. They are only taking off millimeters. Which is why some heads and blocks can not be decked. There are wear indicators on the head and block that can be indicators of it having been decked before.
can you tell us exactly what oil and what the change interval was?
How do you keep track of which screw goes where?
Were the chains and guides on this engine original? Maybe it was said and i missed it but if they were that’s crazy.
Wow inside the engine has burn color, what engine oil they used ?
We need part two :(
suppose the heads need to be redecked as a pair to maintain compression bilaterally?
Look like a good bmw engine 👌
Do you guys have a video on that e34 with the apex wheels
That’s Tom’s car , my service manager . We plan to do a video on it when it’s done soon .
Love
Impressive to watch a legit Bimmer nerd in action. Instant sub. I’m on my 5th Bimmer and I’d kill to have a local legit BMW mechanic so I could avoid my local Myrtle Beach BMW and their pathetic service dept
Great format. Great videography. Great pacing. Next time, prepare a rough script for more smoothness, but even as it is, this was a very well produced piece of content. Subscribed :)
Thank you for this constructive feedback ! This was one of our first . We’re late to the game here but will work on this stuff for the next one 👌
Great video! I just want to ask, how much can this rebuild approximately cost?
About $20,000 with sleeving and all the parts
@@tyspeed24 I have a bmw e39 540i where the same repair will be done. So thank you for the info. I'm guessing the prices will be similar.
They are truly goofy motors. Cross plane, hydraulic lifters, 3 timing chains. They didn't know whether they wanted a High performance engine or a luxury engine. It's a kinda powerful smooth running engine.
It was very powerful for the time.
Seems like they help it back a little with the headers they chose. Supersprint claim big gains with their headers on this engine.
So, if I buy a use BMW and want to have the motor checked and this done, how much?
Great comment about organizing parts. Without parts tracking, you’re definitely screwed.
Where in USA are you @ ?
Can you ask if the owner might comment on his maintenance details?
i was the 1000th sub ! lol
Never seen 1 of those engines make half that many miles.
Con una llave inglesa no debes aflojar ni apretar tornillos o tuercas porque las pasas . Saludos
One amazing engine, arguably the best M5 engine ever. (V10 is unreliable)
Appreciate the video but the audio is low.
Man the owner of that car took great care of it.
should make the rebuild a mini-series
Nice, I have a shop in Howell. We specialize in Land Rover.
I’m sorry 😂
@@tyspeed24 🤣🤣💰💰💰💰
Price ?
post that m5 touring...this year!!😂
Somewhere over the rainbow is playing gently in the background
This engine is from a time when bmw made good engines.
Couldn’t agree more
B58 and S58, please hold my beer.
best V8 BMW ever made
Great video production, info and outcome for a channel with only 1300 subs. New sub from me 👍💯
