Looks like the mechanic has screwed me over. My only recourse now is finding water damage, but it's looking more like a new engine. To note, when I tried to jump it after it died, it tried to start but smoke eventually came from indeed the intake. Thanks for the input guys |

Before trying to lay blame on the mechanic, he didn't "finish off" your engine. It was dead when it died out in the mud. At that point the failure had already occurred.

Sounds like it. I have accepted that it's cooked just praying it can be blamed on water damage

I was half joking. Obviously the engine was f'd when the mechanic received it...But it seems like he did "finish it off" since it totally seized when he managed to get it running briefly.

it's with great regret that i have to post this. Last Saturday, my S65 lost oil pressure and keeled over dead. RIP @65k miles. No warning. now looking at an expensive repair bill. i've just logged my complaint with BMW, don't expect any recourse, but had to log the complaint. get your Rod bearings replaced....

Lost oil pressure which led to engine failure? Or the bearings spun leading to engine failure? |

I'm also curious has anyone been compiling all these failures into a spreadsheet? Wonder what is the distribution of the failure mileage is... what is the mean / median mileage, different percentile point etc? Will be useful to help people to decide when to change their RB based on how risk adverse he is. If no one has been doing that, might be useful to start a google sheet for that so we have the data in more summarizable format? I remember someone tried to look at the failure v.s. various thing such as oil change interval etc, someone must have compiled some spreadsheet at some point? |

I have been following failures for years and found nothing that gives any particular owners hope, other than that the odds are still extremely high that nothing will happen.
I’d guess maybe 1% of cars have failed, and not more than 2% and that another 5-10% have had rod bearings replaced preventatively. |

the car did have a SC on it when first built, this is / was the Powerbeast car that IND built. I don't know how long the SC was on it. Oil change interval for the 3yrs i've had it has been every 5k miles . Blackstone report done 2yrs ago was solid, clearly i should have stayed on top of this better. Was on the track at the time. Shifting from 4th (~7k rpm) into 5th, then lost compression. Was my weekend car. |

No direct correlation has been shown between SC and rod bearing wear. Most cars that blow up never had one.

Mains are a whole different animal. Like I said, no relationship with ROD bearings.

Well, kind of. All rod bearing oil flow passes through the upper main bearing shell to the oiling passage from the main journal to the rod journal. A main bearing moving more than about 5 degrees will block the oil supply port in the upper. Granted, that's still a main bearing failure, but leads to a pretty spectacular rod bearing failure.

would love to know who has been and get in touch and take a look at those data.
at the very least will be interesting to see if we can have some estimate the failure rate, how it relates to mileage etc... |

The failure list from our small Bimmerpost community (forum) is only the tip of the iceberg ... *The Worldwide* S65/85 RB failures , that matters ! Bimmerpost is NOT the world . It's a German lottery ...
