There is a specific run-in regime for any ///M car that requires an oil service before 2k miles(?) and no revs beyond a certain point during break in. I'd suggest you be mindful of those guidelines for this new motor to have everything seated and settled properly or you'll likely regret it.
On my end, I bought an M6 from a dealer in Chitown coming up on 4 years ago at 28K and I've religiously changed the oil every 5k miles with Blackstone testing to be sure I'm in good shape to my present 49k miles. I drive assertively, but don't beat on the car, often hitting the limiter on the highway just to 'clear my throat' with no problems. To date, I consider myself to be lucky I own one specimen of only 1933 F13's to come to the US. <knocking wood> Last edited by Cincinnatus; 01-16-2021 at 04:51 PM.. |

For the OP, I wouldn't be worried about a new factory motor. Break in is critical for these things and seems to be critical for oil ring seating and how much oil it burns (they all burn it, proper break in seems to keep it minimal). Regarding coating the DPs, I've just sent a set off to Swain for whitelighting. |

Congratulations on the dodged bullet!
I am very curious what the failure was, but I suspect there was considerable damage if they are coming out for a full new engine versus a reman. Who knows, perhaps it's just a warranty company that likes to pay $46,000 for a blown motor claim. For what it's worth - if I were to venture a guess, this is not a defective rod bearing issue.

My tech only pulled the number 4/8 bearings and they were burnt up. Metal shavings everywhere. Copper in the pan. And the oil filter looked like a puddle of glittered oil. So yeah they are replacing everything including turbos to not take a chance.

I would be VERY interested in them checking out the machining on the crank....

People are going to point to a manufacturer defect, but I'm just not convinced. |

While yes, tolerances can cause bearing failure, so can detonation, drops in oil pressure, or simply continued operation at high loads without allowing oil to come up to temperature. The fact that this car was just purchased, at auction, with low miles - I think someone might have previously had a failure, maybe put a set of bearings in the car, and sent it off to the auction. It could have also been the tune, since OP said the car felt sluggish - perhaps there was something else. We could sit here and speculate all day but personally I'm not willing to point at a S63 tolerance fault with what I've read thus far. |
