Yikes, that's me! A little background on my car: previously owned by a BMW mechanic and during my ownership was properly warmed up, 5k mile oil changes, super clean and runs great. These are the bearings though! I was not expecting that lol.

I can't recommend ACM enough! I sent Matt an email and he got back to me within 10 minutes. We then scheduled a time for me to drop off and pick up the car as I passed though from CT on a little road trip. Matt gave me a few phone calls while they had my car to keep me updated on everything that was going on. Communication is key and made me feel very comfortable and confident that I left my car with the right people. We even decided to do a more thorough service and install new motor mounts, change trans, diff and brake fluid (along with a pesky TA) while it was on the operating table.

To anyone who is thinking about a RB service: just do it...and call ACM! My car feels great and I am no longer stressed about it. These are the kind of people that are on your side and not out to rob you. Exemplary communication and quality of work. Thanks again!

It would be very helpful if pictures of WPC treated OEM bearings to GTS specifications, with ARP hardened rod bolts are posted after 30,000 miles or more.

What seems to be missing is the comparison.

While the "problem" is well documented....

And the process has been discussed ad nauseam....

the solution seems to be somewhat less documented...

So what we all need is pictured of either BE or WPC after equal amount of mileage.

Without that, for all we know, the WPC and BE RB looks exactly like the OEM ones. And if so, what would that mean?

Wow! Those look awful. Good thing the owner had them done.

Paul,

Thanks for the feedback! I'm glad you were happy with her stay here and glad we were able to sort it out entirely while you were traveling.

Sorry for the delayed response...Short staffed over here in the shop so we've been a little jammed up.

Yes, you raise good points! There is so much coverage of the factory removals and you have to consider we have only started documenting these more thoroughly the last couple of years, but have been doing them long before that!

We agree that we'd like to document more bearings after tens(x4,5,6) of thousands of miles after the upgrade. We have pulled only a handful over the years with the upgraded bearings in them, but that was long ago. The fact that they were in excellent condition, showing no signs of wear in a duration of approximately a 30,000 mile average was a very good sign, but it was still on the lower end of the mileage spectrum. Out of the thousands and thousands of S65's out on the road, we knew it was not a large enough sample size to rely on for data gathering. However, compared to the stock bearings we pull at that range of mileage, we saw the difference and felt that there was validity to upgrading and kept moving forward providing the service for the community.

There are issues in accurately gathering post bearing data too though. Aside from aligning all of the exact variables from each car (because all bearings show wear differently from each car we pull), we also have to consider the most realistic issue that 99% of customers do not want to spend the money again on the service.

Strengthening internal components with proper care should ultimately increase longevity in that specific area. With all of the awareness around the rod bearing issue, current owners that do this are now on the zero mile rod bearing. In theory, the majority of current owners should be treating the initial warm ups and oil changes differently than original owners did back when these were new and the issue was not surfaced fully. Hopefully this care after the upgraded bearings will ensure that we'll see these M3's on the road decades from now.

This 2008 E90 is a little different than the others that we've documented here. Disassembling some of the lower components on the lift while on our way to performing the rod bearing service, we discovered that there was a crack behind the alternator that was bandaged up. The damage does not appear as though it was from a front end collision, but perhaps an error while that engine was being installed back into the car....not quite sure. Regardless, instead of investing in that engine, he said he would bring us another one.

These are the bearing pulled out of the customer supplied long block, which according to the yard he got it from is a 2008 with 37,xxx miles. The bearings tell a different story. With no scoring done to the crank, we upgraded the rod bearings and did a bunch of maintenance items such as oil filter stand gasket, belts and tensioners, valve cover gaskets, cooling system overhaul, cleaned out the secondary air passages with the manifolds off, and spark plugs.
