Old Parts Source is excited to announce that many of its popular pistons are now supplied with a high-performance, antifriction coating. Old Parts Source’s coated pistons feature a state-of-the-art coating to extend the life of the engine and eliminate piston scuffing problems. Benefits for classic car hobbyists and high performance enthusiasts include improved piston life, better cylinder sealing, and the elimination of cold start scuffing. The coating is applied in a highly advanced, computer numerical control (CNC) process that leaves no overspray or coating in the piston ring grooves.
A coated piston can be considered as “insurance” against piston problems. Originally implemented in racing, antifriction coating allows the engine builder to take advantage of extremely tight clearances to reduce blow-by and cold-engine piston noise. Cars with a history of overheating, detonation, or scuffing will see an immediate benefit from the coated pistons, and customers will enjoy many years of problem-free operation after installation.
The coated pistons can be installed without modifying wall clearance, and Old Parts Source offers the coating standard on many popular pistons at no extra charge.
