Camshaft

Common signs of camshaft failure include persistent valve train ticking/tapping noises, engine misfires (P0300 code), reduced engine power, metallic debris in the engine oil, and check engine light codes related to camshaft position sensors or VVT timing correlation.

Single Overhead Camshaft (SOHC) engines use one camshaft per cylinder head to operate both intake and exhaust valves, whereas Double Overhead Camshaft (DOHC) setups use two separate camshafts per head—one for intake valves and one for exhaust valves—allowing more precise timing control.

Flat-tappet camshafts require assembly lube containing high ZDDP (zinc and phosphorus) and an immediate break-in period running the engine between 2,000 and 2,500 RPM for 20-30 minutes. Roller camshafts do not require this aggressive break-in procedure but still benefit from high-quality lubrication.

If you want daily drivability, stock fuel economy, and seamless factory ECU tuning, choose an OEM replacement. If you desire extra horsepower, racing capability, or an aggressive exhaust note (and are prepared for custom ECU tuning), select a performance grind.

Provide your vehicle's VIN, engine displacement code (e.g. 5.7L V8, 2.0L Turbo), and year of manufacture to our sales technicians at +1 (855) 613-4411 to guarantee 100% compatible camshaft fitment.
