Valve Covers

The team here at CMA's Colonial Nissan understands how crucial parts like valve covers are important to your safety on the road. These protective housings seal the top portion of your engine's cylinder head, containing oil while preventing contamination of internal components. Valve covers protect the valvetrain mechanism including camshafts, rocker arms, and valve springs from dirt and debris. When valve covers fail or develop leaks, engine oil can escape and cause significant damage to surrounding components and create fire hazards.

Understanding Valve Cover Operation

Valve covers create a sealed environment for your engine's upper valvetrain components while allowing for thermal expansion and contraction. The cover houses oil that lubricates moving parts like camshafts and valve mechanisms during engine operation. Your Versa valve cover includes gasket seals, mounting points, and often integrated features like breather systems or coil mounting locations. Modern valve covers incorporate internal baffling to control oil movement and maintain proper crankcase ventilation. The cover must maintain its seal integrity despite constant temperature changes, vibration, and exposure to engine oil and combustion byproducts.

Common Valve Cover Failure Points

Valve cover gaskets typically deteriorate after 70,000 to 120,000 miles due to heat cycling and chemical breakdown from oil exposure. You'll observe oil seepage around the cover perimeter, often creating visible leaks on engine components below. Plastic valve covers can crack from thermal stress or impact damage, while aluminum covers may warp if subjected to overheating conditions. Oil leaking into spark plug wells can affect the ignition system, causing engine misfires and reduced performance that requires immediate attention.

Advantages of Genuine Nissan Valve Covers

Genuine Nissan valve covers offer precise fitment and materials specifically selected for your engine's operating environment and temperature requirements. At CMA's Colonial Nissan, we maintain inventory of authentic valve covers that include all necessary sealing components and mounting hardware. Generic aftermarket covers may use substandard materials that crack under thermal stress or fail to provide adequate sealing performance. Your Kicks was engineered with specific valve cover requirements, and genuine parts ensure proper sealing and extended service life. We understand that authentic components protect your engine while maintaining factory performance standards and reliability.
