My E92 M3 EXPLODED! S65 Total Engine Failure

Nightmare coming true....Are S65s really this unreliable or is this just bad luck? Maybe this is why BMW ditched the V8. It was running and driving so well until all of a sudden......

@@oldfashionedwrx3574 Doesn't change the fact that they are crap and go out after 30k miles. I wouldn't expect Subie to think engines can go past 30k before they need a rebuild, though. Engine bearings should last hundreds of thousands of miles. My 500hp Lexus has over 150k miles on it and will smoke the shit out of either of those trash Bimmers and needed a rebuild.

[@Dewree69]

Seems like this was a problem in timing. This engine has hydraulic timing tensioners, and if one gets stuck due to varnish / not being serviced regularly, they let off the tension and your valves can skip timing. That weird sound you were hearing before could be chain slapping the tensioner or rattling about. If you're thinking about rebuilding this engine, probably the best place to learn is M539 Restorations channel. He hand built this baby on camera with all the torque specs and proper factory procedures, a real goldmine of information. I really hope this won't mean you're selling the car, because this is a great car for the channel!

I had the Rod bearings done on my E90 M3 after a ton of research. I fortunately was steered in the direction of experts who advised that rod bearing replacement isn't a straight forward job if you do it correctly, as in, measure for wear and tear as sometimes you may need to use different size bearings. Also, it has been determined that the main bearings wear out at a similar rate so they should be replaced as well when doing the rod bearings. After having both done, I am so pleased for the peace of mind very time I drive the car. It's my daily and I love it. If you go for a quality rebuild, you'll have the same peace of mind and will experience this awesome car for yourself.

Vanos system And the timing You should do it before you go for a drive or test it before Even with the new engine change the vanos and the timing it is always a good idea to for these motors

[@gt1r]

No, S65 has dual vanos which rarely ever fails. S65 also uses hydraulic lifters, so no need for valve adjustment…and zero reason to ever reset timing unless you replace plastic OEM vanos covers with metal washers.

[@onewaylos5578]

One of the best editing channels on KZbin keep it up

[@matt13ross]

Appreciate that thanks!

[@1kontrabida]

KZbinrs made the S65 and S85 engine trending on rod bearings issue, You should check the forums on the S62 engine and the dreaded carbon build up it was like a virus that at the end of reading the threads u would feel u might have a carbon build up issue…This type of engine issue became a plague up to this day, which begs the question that ive been meaning to find out as to how many engine failure these engines have that was caused by rod bearings? and not user error because ive only seen deep scouring on a handful but no bent rods or engine failure. Ive owned and still own M cars and have them all boosted with all stock internals. Per my experience for this specific engine i had the VF and The ESS supercharger on my e92 and can't complain and didn't mess with the rod bearings or whatsoever. I think the key on the cars is first read manual i know its boring but BMW didnt just produce the manual just to look proper and cute at the same time. Proper warmup is key i mean it should be on top of ur list. At the end day i'd say get an oil analysis from blackstone first should be in order, next would be compression and the usual suspects on checking the health of the engine before doing the surgery on something not needed to begin with. I hate to say this and sympathize as well but my verdict is user error. Btw before i forget make sure ur tools are up to spec specially torque wrench and example would be just simply dropping this tools can mess their calibration. And as car enthusiast to another… my advice is to "Treat every build as if it is ur last and always be positive it will help u greatly not just in building ur dreams cars but in life in general" Hope to see the rebuild, learn from it and make it better" Good luck

[@fhash_4827]

This is such retarded levels of copium to defend a shit design from BMW. It's a shit design, just like b6/b7 Audi S4 plastic timing chain tensioners and early c63 head bolt. A shit design is a shit design. Idk why people defend these piece of shit s65 and s85 engines. BMW is all about the inline six cylinder anyways.

[@EtowahValleyRovers]

You could hear the engine rattling on start up at the 56 second mark. Weird because the inside of the engine looked super clean in your previous video

[@johnlu8495]

Pretty sure this is totally normal for S65 starting up. If it's not, then... ah fk... cos mine does that if I haven't started it up for a day or two.

[@Nitro-fu7rv]

Probably a tensioner pumping up

[@createanddestroy]

You have some slight form of bore score in 2 silinders. I would personally rebuild, if the crank (it probably will if the bottom half of the rod is still on there) is ok it is salvagable. Sure it takes time and money but you'll learn a lot from it.

My advice would be with every car that hasn’t ran in a long time and you are not familiar with the history of it, do a compression test! With most engine blocks it is not that much work to reach the spark plugs. I won’t say that this would have prevented the engine malfunction but if it would make that much compression, and you would enter the cilinder with the camera, you would already see some damage and possibly prevent further damage! However nice car! Hope to buy one myself to restore it

Upper rod bearing failure, caused the piston to fall too far in the cylinder bore, rings then hit the sleeve stopping the piston, rod then went through the piston causing the damage you’ve got.

[@e39lover73]

@@JC.LC. the views part is true for sure, the performance wouldn't be all that crazy if a difference, the V10s weighed a significant amount more. But I won't lie it would be a cool custom one off swap

Pushing a car, in rain and in crocks was a humanizing bit of character development! Yikes that cylinder is hamburger

Hahaha, thanks!

Hey first time watcher 👋 legit felt your pain as I watched 😨

[@matt13ross]

Thanks for tuning in! Engine coming out soon

[@DaleSteel]

That ticking at the front is water pump mine sounds same.

[@pjmccracken]

Sorry for the loss, but your misery is our content. 🤣That block is toast, get a replacement block or engine and do a full performance build as much as your budget will allow. Look at this way you will end up with a reliable car and not driving around wondering if that day is gonna be the day it goes boom so in the long run you will enjoy the car more, secondly your subs get some very interesting content along the way. Everyone's a winner!! Wish you the best of luck with it and I will be staying tuned.

If I saw this video before hunting for a good spec E93 I probably wouldnt have gone on the adventure. Fortunately I saw too many awesome S65 YT vids and did it. A lot of PM money but finally got it in near show room condition. Sorry for your loss- Mine had the bearings done a year/8,000miles ago and still has a full warranty until 100K. Its not on the market but if someone throws 65G in my face *maybe ill take it. Really curious what you find out as for the cause- If I had to guess Vanos related or the bearings didnt take.

[@JCe92m3]

When you showed cylinder 3, my jaw dropped🫣

[@pubscherr]

It certainly seems like it was a problem that had been growing since before. I had the same car for several years and had issues with the rod bearings sticking. But I caught it early.

[@livinglifeboosted1642]

I wonder if if it jumped timing and shared a valve off which caused the piston to explode taking the rest of the engine out on the way down I have had many of these engines and the only time I’ve had them fail is when it has been Rod bearing related I did notice in your clip when you started it there was quite loud rattle for a few seconds while oil pressure was building and this could’ve been a bad timing chain so it would be interesting to see if it is actually jumped timing The loud rattle could also have been lower oil pressure or a lazy oil pump theory of course

[@andrebrown8792]

Being that the rod bearings were just replaced, I was leaning towards a VANOS issue for that noise. But I’m not sure that would cause a piston to detonate like that. Possibly something VANOS failure related ran through the engine and blocked oil flow to that rod bearing, then it let go due to oil starvation. Interested to see what the crank bearings look like. Good luck!

[@user-eu9ub8kj9j]

Vanos doesnt fail on s65’s unless its the plastic cover on the end of the cam, vanos failure was only a thing on early s85’s not s65’s

[@DailyDrivenClasssics]

Possibly they used silicone to reseal the engine after rod bearing change. They used too much-> excess silicone magically ended up in the oil squirter which caused the failed cylinder to detonate due too lack of cooling. Possibly also the reason why the other cyl 4 driver side had scoring because of lack of cooling-> too much thermal expansion-> scoring.

[@andrebrown8792]

@@user-eu9ub8kj9j it’s rare, but happened to my neighbour.

[@matt13ross]

No silicone used by me!

[@DailyDrivenClasssics]

Nice vid. Cylinder number 4 driver side was defo not fine. S65 is made from alusil and the bores need to be smooth smooth. Thats also why you cant see cross hatching, since its not meant to have it. Piston could have exploded because of many reason. Maybe unsufficient lubrication from the oil squirter causing too much heat. Maybe stuck valve and piston flew in there... Also, if you dont want the engine, you can send it to me lol :)

[@matt13ross]

Thanks for the info!

[@ROMAN-oy5ju]

Keep us posted please looking forward to solutions

[@avusm395]

I owned an '11 M3 with an S65 than seized up on an off ramp. It had 38k miles and was classic rod bearing failure. Covered under CPO but I didn't keep it long after they put a replacement engine in. Hopefully the aftermarket has developed a full proof solution to this issue.

[@matt13ross]

No full proof stuff. Just replacements every 80k miles or so. Sad

@@TheReaper42069you kids are funny, just because you slap in a motor that makes a gazillion horsepower doesn’t mean it makes the car better… it literally ruins the characteristics and the whole purpose of it being what it is. also, s65 weighs less than a LS3 and that’s without those gay ass twin turbos

[@camcam1676]

well the sound sounds like timing chain and tensioners where worn out. or the rod caps got mixed up. or the rist pin failed.

[@MrVangboi05]

My guess is oil starvation. That engine oil sensor was just at about minimum and driving it in the hills would do it. Sucks that this happened to you.

[@PompeyMatt17]

maybe spun a rod bearing allowing the piston to rattle in the bore and hit the valves

[@GTR003121]

Daaaaaamn, piston nuggets!

[@Vikturus22]

The failure on that cylinder was the rod journal. Either was not lubed enough or the assembly was not correct. The engine (especially that cylinder wall) is toast, might be able to pick up a used high mileage one for cheap and do a full rebuild! (Streten at m539 did full rebuild on his e90 with lighters pistons and bigger cams so possibly an idea for this?)
