BMW Rod Bearing Failure
We are a BMW specialty shop and BMW owners often ask us about rod bearing failure and how worried they should be about this happening to them. This is catastrophic for an engine and we have seen it many times. Below is a brief overview of the contributing factors for premature bearing failure and some preventative steps you can take.

Preventing Rod Bearing Failure
BMW owners should consider replacing their rod bearings as preventative maintenance to reduce the risk of serious engine damage in the event of rod bearing failure.
- Owners of S54/S65/S85 engines should change their oil every 10,000 miles on cars driven daily.
- The original rod bearings should be replaced by 70,000 miles.
- Consistent BMW maintenance with a BMW safe oil from a BMW specialty shop is crucial.
The correct oil must be used in your BMW.
Rod Bearing Replacement on 2013 BMW M3
We received this 2013 M3 to install a VF595 supercharger kit. After discussing the fatal rod bearing issue with the owner, we decided to first replace them with a set of bearings and ARP bolts. This corrects the overly tight rod bearing clearance for use with factory 10W60 oil. At 40k miles, the factory rod bearings were showing significant wear!
