The BMW S65 engine! Renowned for its high-revving performance, is unfortunately susceptible to premature rod bearing wear. Derived from BMW’s F1 race engine program, features narrow rod bearings with reduced clearances. While this design enhances performance, it also increases the risk of bearing wear, especially if not properly maintained due to the engine’s tight tolerances and high RPMs, leading to insufficient lubrication and increased bearing wear. If not addressed, this can result in catastrophic engine failure. It’s advisable to proactively replace the rod bearings around every 50,000-mile mark to prevent potential engine damage. Some enthusiasts recommend even earlier replacement, especially if the vehicle is driven aggressively or used in track conditions. For those looking to replace their rod bearings, the WPC Treated Race Series Connecting Rod Bearing Set offers a superior solution. These bearings undergo WPC treatment, a process that enhances surface hardness and reduc...
