Product Q&A
Q:Why does the engine still smoke after piston replacement?
A:
Persistent smoke is usually caused by unremoved carbon deposits, worn piston rings, aging valve oil seals, or insufficient break-in. It is recommended to replace piston rings and clean combustion chamber carbon synchronously during piston replacement.
Q:What is the main cause of piston ablation and cracking?
A:
Common causes include long-term overheating, poor lubrication, inferior fuel quality, excessive load operation, incorrect injection timing, and clogged cooling passages. Standard maintenance and operation can effectively extend piston life.
Q:Will new pistons affect engine power after installation?
A:
Qualified OEM-spec 3092721 pistons will not damage engine performance. On the contrary, they restore standard cylinder compression and combustion efficiency, effectively improving power, torque and fuel economy.
