11 E90 Rod Bearings 50k Miles - MRF Engineering

[Siajoon]

+1 for Malek as well, I recently got my bearings replaced on my e90 M 2011 with 67xxx, like many have already mentioned he was an absolute pleasure to work with.

I will recommend him over and over again. I felt completely confident in him when dropping my M with him.

The new motor mounts are night and day... I was at a red light the other night and I seriously thought my car was off..... I couldn't feel any type of vibration.. I thought to myself did I just stall.... hahahah

Anyways....8400 revs never felt so good.

Zero evidence of impeding failure given those bearings look better than any of the 100+ sets I've swapped. Seems like you bought into the paranoia.

Glad you got them done and Malek is among the best out there.

At the risk of getting into a pointless argument I will just say I am an experienced mechanic with engine building experience and these bearings are worn to an unacceptable level, indicative of premature failure. How worn based on pictures is subjective at best (didn't measure, but to an experienced eye doesn't need to be measured to know it's unacceptable), and comparative wear is pointless.

I agree I have bought in. Paranoia? Ok I guess I agree. But the objective evidence is not debatable.

I'm not here to convince anyone they should change their rod bearing any more than they should perform any other maintenance or repair on their M3, but please show me and other members the same respect and do not patronize our contribution and feedback to the community.

There is zero disrespect in my post. You didn't provide any evidence to support your "impending catastrophic failure " claim. Especially since your bearings were in better shape than the majority of examples posted on thoits forum.

Did you have bearing wear? yes.
Was it excessive? no.

Given the evidence in this forum, your situation was better than most.

Ok I'll give you the benefit of the doubt. I thought the bought into the paranoia comment felt a bit patronizing because I find myself much more experienced mechanically than most and to me this is an obvious issue.

Cheers

Given your experience, would you like to shed some light on this issue? We'd love to hear your professional opinion.

No need to beat the dead horse.

its an issue. people need to accept it.

There was someone else on this forum who use to make fun of people buying into the paranoia. Until he started having a rod knock and then he suddenly shit a brick. He was lucky that Malek was able to save his engine. To each his own. It wouldn't be the first time that a manufacturer made an engine with a significant defect.

The same thing can be said about the Porsche engine with the IMS bearing. So people chose to ignore it and some chose to replace the bearing.

How long did it take
