Not my car, currently swapping in BMW reman'd replacement for a customer.

Good pics tough to get at the moment as the ventilated area is just above the steering rack.


This was my stopping point yesterday.
Did BMW not cover these engines under factory warranty or are you guys a tech for a BMW dealership?

Just shocked how many engines 'regular guy' has seen that failed. I have a few friends who are techs at BMW dealers that see M3s often but do not see anywhere near the failure rate as seen posted in this thread!

In my case, the 2010 w/ 26k, car was out of warranty. I am not 100% on why, but I believe it to be a salvage title due to water damage. It wasn't purchased with a blown motor, that happened to the current owner.

I don't think voting for a car that isn't yours is quite the idea.
If the owner comes along later and votes himself then it gets two votes.
The whole thing would be pointless if everyone starts voting in cars that they have heard have failed.

I think there is a definite correlation between these failures and hi-revving/redlining the motor. If you consistently do, you would increase the chance for this kind of failure.

The owner isn't a member here. And what difference does it make whose car it is? It's the data we're looking for, right? I happen to own an S65 powered M3 myself, so it's certainly relevant to me.

I am not a tech at a BMW dealer. I've just collected these photos, mostly over the past year. The photos come from a variety of sources.

But let me point out something that might not be obvious. These first two photos show signs of rod bearing related issues. The rod big end was super heated and turned blue. The discoloration is a strong sign for rod bearing failure.





But the next photo does not show a rod bearing related issue.



The first two photos show discolored rod big end, but the last photo does not. The super heated rod big end are signs of too much friction such as rod bearing failure or friction caused by too little clearance leading to bearing failure. The lack of discoloration in the last photo implies a slightly different type of failure such as rod bolt failure.

Ah that makes more sense. I thought you were just seeing all these failures firsthand.

Why not add the related OCI to each engine
?
Anyone taking the OCI to high mileage or not changing before AND after a HPDE should have their head examined.

my oil analysis taken after 7500 miles and 3 HPDEs suggests otherwise.

BOOM!

Do you mean blown up engines by a supercharger? There are several blown motors by several S/C companies out there!

I agree with Clem and added an '11. It belonged to a close friend who is not a member of forums. I know the car well and have tracked it myself before I bought my '11.

His was a 2011 E92 with 16000 miles, stock except for SS brake lines. He had participated in several HPDE events and was on VIR coming through a turn at 100 when the number 5 cylinder exited the engine, creating a large fireball that melted the back half of his car.

I do know that he frequently had that car over 100 mph and it has seen 170 (ED car, no speed limiter). I also suspect some of his high speed jaunts on the way to work in the am were done before the car hit normal oil temps.

On the plus side, BMW bought it back from him after repairing it at a very fair price.

I agree with SFP that if members are posting for blown engines they heard about from a friend or any other source then this poll is not reliable in providing accurate numbers.

I don't need evidence to tell me that spinning a crank at 8400 rpm consistently is going to greatly increase the chance for failures like this.

I guess common sense isn't that common anymore.
