The same thing happened to Speed Academy! they did a rod bearing replacement and the car had catastrophic failure miles later. Probably has to do with tolerances of new bearings.

bro dropped the hardest intro to cylinder #3 😭

[@acroracing]

😂😂😂😂

[@kwozzie]

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.

Im a GenX who owned 11 BMWs in my life. Whenever I heard an engine noise, I stopped the car and towed it to the dealer. It was an expensive hobby. 😅

[@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 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.

[@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.

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.

Someone needs to make a Coyote swap kit for these. Already is a LS swap kit for E92 but the Coyote is closer to S65 high revving nature.

[@matt13ross]

High revving LS??

[@PompeyMatt17]

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

[@Rockport1911]

I guesst not ALL bearings where changed during the first videos? Sad to see this engine go, that " Midnight Purple" on this E92 sure looks nice :)

[@matt13ross]

All the rod bearings were changed. Can't change anything else without taking the whole engine apart lol

[@Loukanopoulos]

My bet is a vanos hub cover failing which clogged your oil pickup

[@MegaRetr]

Sorry to see Matt

[@ForgedShaft]

looks like the piston shattered first, i guess you will find out when you take it apart

[@bobl78]

maybe the timing chain broke or jumped. The sound in one of your other videos sounds very much like a timing chain issue

[@AWD_T]

Bearing inspection next. How far down the line is that rod bearing from the oil pump? It wasn’t knocking so I’m real curious. Locked up wrist pin would be my guess.

[@orionsires]

This was painful to see! Hope to hear what the cause was, new to the channel but happily own a problem free e92 m3 stock let it warm up before every drive and it has 102k on the clock. Never had any issues fingers crossed. I would never do rods myself mostly because I would fuck it up. Much respect.

[@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.

[@superlowian]

This is what happens when you get overspray on your car

[@matt13ross]

LOLOL I love this

[@sethlozeau2962]

It’s unfortunate that the BMW had a catastrophic failure, but it could be saveable. You could do a full engine breakdown and see how bad the damage is and see if it can be massaged with a good bore and honing. Thats good content! If it’s too far gone, LS swap 2.0! This time, supercharge it! Or get a wrecked Hellcat and swap the engine from that. Don’t let this hiccup get you down, Matt. This is creating content for your channel and a new adventure. Keep up the good work! I’m looking forward to what you choose to do with this one.

[@Omegaman1969]

Wow, looks like the big end bolts weren't tight on that rod.....ooooooops

[@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!

[@BmwMe-uh9sy]

Nah we aint gone help, you got porsches and brand new trucks sitting in your driveway you can easily fork out 7 or 8 grand for another motor off ebay stop penny pinching off people from here.

[@matt13ross]

Lol at brand new truck

[@williammorris3334]

I wanted an E92 for years. Watched all the fanboy channels,but then I started learning about 8 mpg when driving it hard, throttle actuators and rod bearings and BMW in general. I ended up with a 981 Boxster S and because of its design I can do all the maintenance myself. Once the panels are removed everything is accessible as it can be with a mid engined convertible. My car gets 17-19 mpg when driven hard in the mountains. Because it weighs 600 pounds less it is actually just as fast with the PDK. The interior quality is much better than BMW. The car shares about 2/3 of its parts with the 911. I say all this for those contemplating a sports car.

[@IvanKorsinsky]

If your concerned about MPG you shouldn't be looking for a sports car. If your concerned about reliability you shouldn't be looking for a sports car. Those are just attributes that come with these cars. It's to be expected.

[@R03333]

981 is more expensive than the E92 though. Plus only a 2 seater, can't put the dog in the back seat.

[@TassieLorenzo]

@@IvanKorsinsky Hmm, the original Acura NSX was a sportscar that competed against the BMW 850i^, Ferrari 348 and Porsche 964 and others and is basically as reliable as a Honda Accord? Same for the S2000 that is basically as reliable as a Civic? 🤔 It certainly can be done. ^ (I guess the BMW 850i was more of a GT back then, they did have the Z1 roadster in '89-'91 or you could count the E30 M3 as a sportscar despite the more sedan-derived body style. I guess the S2000 was a competitor to the basic 2.5 Z3, but not necessarily the more powerful Z3 M.)

[@glennarnold3970]

Matt the best m3 is an m3 without the s65 LS swap it or in my case ford fg turbo barra as much as i like the e90 e92 i would never go build or by a bimmer engine when my other 335i needs an engine LS or barra all day long but i feel your pain that's why mine is barra powered finding a good s65 is still a crap shoot you get one BUT then your obliged to do the bearings in it even if they have already been changed you are on a slippery slope my friend but keep ya chin up you may find a diamond in the rough cheers from down under
