Hi I just bought very mint condition bmw m3 e92 dct 2010 have 8700 mile on it.
After I read this thread I'm become paranoid with rod bearing issue. I recorded my engine sound and it have ticking sound is my engine sound normal?

[dry87]

Because I'm paranoid I go to my friends house to hear what his engine sound like, he 2011 had 8800 mile on it. And sound very similar. I think my car is fine.


Do u have video that show ticking rod bearing problem?

[Doc Oc]

That's your injectors doing their job. Sounds normal. Below is what your looking for. Not a tick, a knock.

You had a good set of bearings there, looking good and unaffected. I think you made a mistake to roll the dice again with new bearings when you had a good hand.

I just had a chat with the Belgian Sonny-Heyman .
He confirmed that he is looking for a new/rebuild S65 , cause was BF and the motor was total loss..
Car is out of warranty , and the situation is not cheap .

Well I got call from the shop, right away was metal in the oil filter etc. Its the bearings. Going to check to main caps to see if I can rebuild it or not, deff not what I wanted to hear.
Almost exactly 30,000 miles on these new bearings and the car already chewed them up to engine failure, orignal set I changed out at 31k and were worn to copper on several. So yea... not happy.

That sucks. There have been several replaced bearing failures. I was going to wait for 60k to change mine again. How bad was your original set at 31k? What bearings and bolts did you use?

My orignal set had copper showing on most at 31k, thats stock no supercharger. When I went FI I used WPC treated stock bearings and ARP bolts.
Was always mindful of engine but especially after i went FI, never went over 3k untill oil was at operating temp, oil changes at 5k. Oil tests every oil change, which last test showed perfect results 3k ago.
Did everything right and still got bit.

Going to stay positive though, was going to do a stroker rebuild way in the future. Guess I just get to have it sooner now

Thanks man, just got to talk to some people and get a parts list etc together and if to have shop build block or just send it to VAC etc. I know some but not alot about specs etc. ESS did warn me not to go over 11:1 CR on a FI 4.4L stroker build.

How much did they charge?

[Doc Oc]

A blown stroker sounds awesome....and a bit dirty. Good luck.

So changing out the rod bearings still doesn't solve the issue. Where do we go from here? What's to prevent the stroker motor also having bearing issues?

From what I understand really only fix is to turn/mill the crank or with stroker your getting a totally different crank. You then have proper clearance etc, I knew bearing swap was not a fix. Just thought it would buy me more than 30,000 miles!

No, he went with WPC which has less clearance than the OEM bearing because of the coating (it's an OEM bearing that has been coated).

BE bearing was designed to provide the right clearance.
