There are several S85 engine bearing failures in threads over there that occured in the EU according to member Duschaino who seems to have worked on a lot of different S85 engines.

Similar comments came up in the bearing thread. Many people just want to ignore that there are any failures outside the US.

98 RON is the same as 94 AKI. Most of the US is filled with 93 AKI. |

You worked very hard to get some input on this situation from Clevite. That's great. Now most of what they say that disagrees with "your" speculation (and that of our other non engineer experts in the main thread) and you call conflict of interest. You not only call conflict of interest but you call it on only those parts of what they say that you don't find palatable. I don't disagree that there could be conflict of interest but you can't have you cake and eat it too. Clevite claims they do not see clearance as a problem, period. Look, flow rates are cooling are pretty obviously tied to both clearances and viscosity but bearing lubrication, specifically pressurized oil fed journal bearing tribology is not a simple subject, not in any way. That is why there are Professors at top Uni's who devote a considerable portion of their careers to this subject. Thus unless we are talking about variation in the oil pressure along the axial direction of the bearing or some other subtlety of the tribology, I'll have to claim ignorance on their comment about "more area". Now matter how much emotion we all have here on this topic. We should accept the reasonable analysis I've done placing this at a maximum failure rate of 0.5% and substantially lower than that during the early E46 M3 bearing situation. Would 0.1% be "better" sure, acceptable, that's a relative term. Would all owners prefer a 0.01% rate, sure. Did BMW believe that the overall financial, longevity and performance tradeoffs were best met with their existing clearances? Yes almost for sure. Let's not forget those that blame the accountants here - BMW is running very tight tolerances, as you measured and as are required to run tight clearances in the first place. This is not cheap and was not a bean counting decision.

Massive hyperbole will be called out, like it or not.

I've been in two situations with BMW where the stakes involved were about the same as being discussed here. One thing I learned during those occasions was that BMW was staffed with good people. Top to bottom. Perfect? No. But then, neither am I. Do I think the S65 is perfect? No. But, despite all the consternation, it remains perfect enough for me. |

Try googling for euro S65 m3 bearing failed cars and see what you can come up with - I tried with little success. |

Doesn't matter anyways because lack of forum threads isn't proof that something didn't happen. We went through this in the bearing thread and many people (including myself) pointed to numerous examples of dealer replaced engines for people not on the forums. I mentioned four from just one of six dealers in my area, and Kawasaki mentioned something like six just from his local dealer. |

They grandfathered a warranty which covered the engine. Correct? They didn't cover the cost of the engine. They allowed a warranty to be put in place only 5000 miles out of warranty. Correct?

You would have to be so far out of your warranty such that the bearing failure could be attributed to normal wear and tear. At 100k miles, you're more likely to have bearing wear and thus a small chance of ruining your engine (however I still wouldn't accept 100k as a lifespan of an engine) . With a young engine it's reasonable to expect that your engine won't grenade for any reason other than abuse.

This is a known issue in the 2007 and 2008 cars. They had a supplier problem in that period. I had a 335i, yes I know it's not the same as the S65. At 42,000 on the clock and still in warranty, I spun #5 and #6 rod bearing. Had metal shavings throughout the motor. BMW blamed Dinan and said they would not warranty. So Dinan footed the bill. BMW will do what it takes to save themselves a buck.

Nice to hear there was a happy ending to this horror story.

this is not correct. Perhaps the work you had done was subpar or it's all in your head, but there's nothing wrong with pulling the motor in a car time and time again.

This is a great article and an eye opener for me. I'm going to get my oil checked out on my next oil change. I hope I never run into this issue!

Hmm...me thinks BMW saw the large amount of research the OP had done on this problem. He documented everything, had all the evidence he could get. BMW probably said it would be best to help the OP out. Better than let him go to a lawyer and get a class action lawsuit off the ground.

BMW does the right thing!!! you are lucky my friend.
on a side note, I thought BMW learned their lesson with the S54 but I guess not. They will issue a recall soon if this gets worse

Thanks so much for sharing your story. And what an incredibly kind gesture from BMW! It's so awesome to see such compassion from them.
Enjoy the new motor! Cheers
