I'm not even going to comment on the first part... my brain is too exhausted today.. however, regarding the last statement.. those are completely different, as one is covered by insurance, the other is clearly not covered by insurance or a warranty in this case. |

The number of hours charged is just that. It doesn't matter if it took them 2 days or 2 hours.
Fwiw I work at a Hyundai dealer and our labor rate is $140. It's different everywhere. |

So, just an update. The m3 is still at the Indy shop. . They ordered the wrong oil pan gasket, and needed to buy a special tool for something. Not sure what.. Maybe stretch tool for bolts??
I’m overly anxious. Only drove this car once. Took some pics right before tow truck came to pick it up. I’ll have pictures of the rod bearing shells soon enough. Any ideas what I can do to get my mind off it? Looking for exhausts, and parts isn’t helping. |

Given there is ZERO possibility to measure the rod bolt stretch on the S65, I have $5 on that they did not have the 6" long T30 for the hard to reach oil pan bolts Sure do hope that is was not the 12-point 12mm socket... As for keeping you mind off the M3... Perhaps bourbon would help?

You're taking care of a necessary preventative maintenance item before driving it, that takes a lot of self restraint! You should reward yourself by getting some mods on the way now to slap on right when you get the car back
These cars are great in stock form don't get me wrong, but the right mods will make it something else..

They have done bearings on e46s. Not sure if that uses 12point or not. Usually most German Indy shops should have the long torx though... Maybe some kind of plasti gauge or something? |

He did replaced the rod bearings and what happened? Makes sense now? |

And, FWIW, 1% would be 660 failures. IIRC, BMW no longer has any original spare long-blocks available for purchase anywhere on earth. That is not positive. Also, look at the condition of the majority bearings that are removed from the S65. Plenty of those engines were well on their way to a major failure. Should we count those in X? Cheers,

Makes me wonder about the 50,000 plus M3 with original rod bearings. You would think they should be blowing up all the time based on the pictures posted of removed bearings since 90% of the sets show premature wear. But that does not yet seem to be happening even though all these cars are now 6-11 years old and the miles are accumulating.
I changed mine preventatively and think doing so is a good idea, but I can understand the logic of those who take the risk. The odds still seem low and people are free to self insure against the risk. |

1) The data presented on this Wiki shows that there is a very real risk of having a bearing tolerance that will cause failure. 2) The flow data supplied by BE during testing clearly shows (does not prove) that bearings with proper clearance have much better flow at high RPM. Better flow equals better cooling and also ensures the hydrodynamic bearing is operating properly. This post nails the fundamental point. 3) The evidence posted on this forum shows that most bearing pulled from S65 engines are in poor condition for their mileage (mine were actually in very good shape (attached) for an S65 at 19K Miles but they still showed the beginnings of wear which is bad for such a young engine). 4) The cost of replacing an S65 is, at minimum, an order of magnitude more than the parts required to change the bearings with BE hardware and shells. Even including reasonable labor, an engine swap is still significantly more expensive than changing the bearings. Also, if you have to pay to have your bearings changed, then you will probably have to pay to have your engine swapped. (I have the tools to swap bearings - I do not have the tools, knowledge or shop space to swap an S65). As for the comparison to throttle actuators and bearings: TAs do not have a cost effective preventative maintenance activity. Therefore, they are a run to fail then replace asset. Rod bearings do have a cost effective preventative maintenance activity. Unfortunately, oil analysis has not shown to be reliable in properly identifying when to change the bearings while guaranteeing zero failure risk. In that case, sooner is better than later, and certainly better than after-boom. Every person on this forum has access to a lot of data. Every member can also make their own choices based on the data. Clevite, King, ACL and others all have design guides that show recommended clearance specifications. These can be compared against the data provided as well as the BMW specified tolerances. OP - sorry for the thread jack. I hope your swap goes well and that you have many happy years with your new car. Enjoy your M. Cheers,
