Just trying to understand, because you said you only looked it up AFTER the engine blew up. When you heard the tick, you didn't read about it before?

So have you had it confirmed by BMW what the problem actually was?

All they confirmed that the engine seized and that there were metal shavings in the oil filter. BMW wanted to charge me money for diagnostics and a teardown, but I didn't pay it. I pretty much think it had to do with rod bearings because that seems like the common theme here on the forums. |

That is the "poor design" in all of this. I firmly believe that OCIs 3-5k mitigate this....

You're one lucky guy to walk away making money than spending money. This bearing thing is like cancer. By the time it comes to a head it's full blown and too late. Kaput. Bang.
I think people who are way out of warranty, the best thing to do is to drive the car hard and enjoy it, rather than worry about it. If the bearings are bad regardless of the way you drive, it will blow up at some time in the future.

Number one, Good for you for not accepting the deep effing the dealership and the company were willing to give you. If the dealership wasn't so short sighted and actually fought for you rather than just telling you this thing was on you, I have a feeling they would still have a customer. Not just a customer, but a raving fan. You mentioned that you had an ext warranty, did the dealer bother to tell you why they wouldn't cover this? (Sorry if I missed it).

To be on the safe side I'd be tempted into getting my crank journals properly machined sometime after the 75k mile mark. Afterwards the engines will be good for 100+k miles of worry free pleasure. Kawasaki is local and could set us up with a quality shop that knows exactly whats needed. I'm about to hit 30k today on my lunch break.... I almost tear up when I think how fast the miles are flying buy. Seams like just yesterday I just picked her up and traveled my first mile. |

This blind faith you have in BMW is something not everyone shares. There are clearance margins that are common knowledge in race engine building that were violated here. Look at Regular Guys thread and all the evidence he has laid out. He is one of many that have come up in the last few years showing the causes to S65/S85 engine failures due to bearing clearance causing oil starvation during cold starts. The evidence is there, what you do with it is up to you.

The S54/S85/S65 proves that they have issues setting clearances! I love BMW too but in this instance they screwed up royally, even more so by not admitting to a mistake and fixing the clearance issues after they first surfaced in the S54! |

I am not saying all engines are going to fail. But there is no way to know at an early stage unless you have an exploratory engine diagnosis (i.e. open the engine and have a physical inspection). You will be extremely lucky to catch it early but most often it's too late. How many of the blown engines showed obvious sign of bearing deterioration at early stages?

I feel kind of shitty without a nice fast sports car.
All I can recommend to you guys whose M3's novelty hasn't worn off yet: get your rod bearings inspected and replaced. |

Same exact thing happened to a local buddy's S65/M3 just last week. Driving fast, wheels skid out from underneath as his motor seized. Car gets towed home, he looks underneath and finds pieces of two connecting rods and pistons inside the oil pan. If I get his permissions, I will post photos. Two rods failed, and it's very clear from the pieces that the big end of the connecting rods were superheated and welded themselves to the crankshaft -- which is what caused the instant seizure and skid out of control. |

Imagine tracking out of a corner, full throttle, and the motor lets go and the rear wheels lock, and there are cars behind you.
