Here at PSI we ONLY use BE Bearings for Rod Bearing Replacements in S54, S85 and S65 engines.

Replacing the rod bearings is one of the 'Big Three' crucial tasks for peace of mind for your E46 M3

The S54 Rod Bearing issue has been sporadic, from 30k to 150k miles, everything varies.

When a rod bearing fails, the oil is unable to properly circulate through the engine.

With the S54 rod bearings out, you can visually see the wear on the inside.

For high-mileage E46 M3s, replacing the rod bearings is essential to keep your S54 engine healthy.
