BMW Rod Bearings Bavarian RennsportRod Bearings

Rod bearings are a typical wear item on certain high revving engines such as the S54 l6, S85 V10, and the S65 V8. Typically needing to be replaced around 60,000 Miles before the possible consequences of a catastrophic engine failure. During replacement, we recommend a coated aftermarket option to prolong bearing life and reduce friction. however, bearings are still a wear item. There is no official replacement interval from BMW, and the last design revision seems to last a long time, but we feel comfortable recommending a preventative replacement every 100,000 miles. Track your bearing wear with regularly used oil analysis and plan on the rod bearing replacement sometime in your engine’s future.
