    I wonder if any of the teams running this motor in competition are seeing this wear? Teams like Turner, Fall Line, etc...

    I don't think we know the full number of failures or how widespread this is. The S54 bearing issue was played down early on too and it was well over 100 motors.
    I agree - but I think the number is still fairly small in relation to how many motors are out there. Unless we are going to see a bunch of motors fail once they get past a certain age and mileage

    So was the S54 issue but that was not evidence of there not being a problem.

    Turner GT cars runs S62.
    GS cars run S65.
    All have dry sump systems...so it's not a great comparison.

    I knew about their Rolex GT car running the S62.

    Make sense they are running dry sump on their Continental Tire Series cars.

    A little more research and I found this on Turners site, not cheap:

    That's right, excellent point.

    However, if they are running these motors all with dry sumps and show no bearing wear that would definitively point to the oil system wouldn't it?

    I've never seen their bearings Click here to enlarge I believe the dry sump solutions are good. We run dry sump systems on S62s, S54s, S52s, M62s, S14s etc and they are great. For the S54, we developed a wet sump comprehensive solution quickly. The S65 is a bit more complex Click here to enlarge

    Do you have or are you in the process of developing a dry sump solution for the S65?

    The S54 is dry sumped to begin with I thought? Maybe not since VAC sells a dry sump kit.

    Similar, but they replace the rod bearings instead of the oil system. Also why the redline was dropped on the M roadster/coupe:

    BMW attempted to blame vehicle owners for the failures early on but eventually started replacing rod bearings, oil pumps, and whole engines under warranty. This fault was attributed to a problem with the connecting rod bottom-end bearing shells that were supplied to BMW by a third party that did not meet BMW's specifications. This problem was fully corrected by BMW on engines produced after 06/2003. A recall was issued to retrofit all M3 cars with affected engines to swap to the proper bearing shells. The recall did not include M Roadster or M Coupe cars with affected S54 engines due to the lower RPM limit.

    I'm going to publicly smack you in a second. If they are willing though to use your car to develop a dry sump setup... I would do it if I were you.

    I'm trying to figure out how to not spend $7k.
