They mentioned a group buy in the original thread so keep an eye out.

Yep, that's simply a supposition with no actual data to support the claim. In terms of numbers of failures, the earlier cars vastly outnumber the 2011+ from what's been seen here on the forums.

Yea, I would be interested in seeing what data points (if any) were used to make this assertion.

Until then, the recommendation from those with engine building experience is that these have a better chance of solving the problem than any others on the market. Keep in mind to fully solve the problem, you need to do a complete rebuild to bring all clearances into recommended specs as these won't address any potential main bearing clearance issues.

The OPs post from your link actually says "Last update March 2015", but even if we use those data points as a snapshot in time with limited data, it supports the site's claim that 2011+ aluminum bearings does seem to have had more engine failures (at significantly lower averaged miles too), than the 2008-2010s, but only by a small margin in total failures.

There has been plenty of discussion, plenty of bantering, plenty of proof, plenty of naysayers. What it boils down to is this: either you want them or you don't. Either you're going to trust a bunch of guys that have a vested interest in seeing this engine survive (as they personally own S65s themselves), who worked with the OEM bearing manufacturer to help the community address an issue that BMW would rather act like didn't exist, OR you can buy OEM bearings when/if you are ever to the point where you're concerned about them.
It's that simple, really. Last edited by whats77inaname; 10-16-2015 at 01:48 PM.. |

Looks like the website is a work in progress. I can wait. But it would be nice to see some test results or test progress on cars with min stack and max stack.
I have no idea of the clearances in my engine, but i want to be sure this is still a one-size-fits-all solution that'll work for me. In the mean time i gotta find somebody around these parts to actually do the swap for me. Thanks.

I'd also like to know if we can continue to run Mobil 1 0W40 or a mixture with some 15W50?
Or is the 10W60 really the recommended oil after a bearing swap? .

Yes, but hopefully BE Bearing will develop the main bearings too.

BMRLVR posted a group buy would be starting soon in the other thread.
I'm sure S85 and Killerfish will have NO INTEREST in these.

Early cars are older and have been driven more, as a general proposition. Makes sense more of them would need work.
The number of main bearing failures reported is about 2. I am not worried about the main bearings. However if you want to spend several times as much money taking your engine apart to change main bearings, go ahead. Even with rod bearings, the failure rate is pretty low. Seems like you have a 99% chance of having no problems. I changed mine preventatively but whether to do anything when nothing seems wrong is up to each owner. |
