11 E90 Rod Bearings 50k Miles - MRF Engineering

I just had my rod bearing changed yesterday by Malek, owner of MRF Engineering in Lake Forest, CA.

My Car - 2011.5 E90 M3. 51k miles, No track days. I baby it 80% of the time and always let it warm up properly. 5k oil changes its entire life. No symptoms or signs of bearing wear. Updated 702 bearings on these production years.

Shop - Clean and Organized like you would expect from a true professional and OCD owner, stated otherwise - the way I keep my own garage.

Owner/Mechanic - Very organized, focused, thorough, and honest. Anyone who is a mechanic themselves knows how critically important this is when leaving your car for someone else to perform work.

Service - Completed exactly within the time estimated and as quoted. I was provided a detailed bill for the work. Malek showed me my bearings (attached) and swapped my motor mounts. My bearings were very worn and destined for catastrophic failure. My Engine mounts had already catastrophically failed.

The engine runs so smoothly now, revs so smoothly and obviously with new motor mounts there is a noticeable reduction in NVH. It also runs much more quietly. I cannot recommend MRF Engineering for this job enough. I know now why so many others have driven great lengths to have Malek service their vehicles. I learned of his shop from the forums and want to encourage others to get this service done. This is not a myth or snake oil. Our engines have a flaw that must be addressed.

Compared to many that we see posted yes, but I want to be clear to everyone that these look really bad. These were well on their way to catastrophic failure and one bearing was actually stuck to the crank. Bearings should not touch the crank journals/surface ever, let alone be stuck. I was lucky, not good and sometimes that's a good thing.

I can also vouch for Malek and his shop. I have a 2011 E90 and our bearing wear almost looks identical. I had roughly 59k miles when I had the service done.

the bearings on my 2011 looked a lot worse than those, but I wasn't the original owner of the car, so who knows the oil change and warm up history...

Looks like mine when I swapped out 2 years ago. I also have 2011 with the 702/703 RBs.

my 2011 has 65k miles on it now. This thread makes me happy that as soon as winter is over and my car is out of storage, I'm getting new bearings installed.

Curious: Isn't MRF often using VAC? What was the reason you went with Clevite?

Learning - thanks

Malek uses the extra clearance VAC bearings with the CT coating. Which are made by Clevite.

+2 for Malek Malek@MRF. Replaced my S65 after bearing failure and also did the Clevite bearings on the new motor. He is the only guy I trust working on my cars.
