Valve Covers: Engine Protection and Oil Containment

The team here at INFINITI of South Bay understands how crucial parts like valve covers are important to your safety on the road. Your valve covers seal the top of your engine's cylinder heads, containing oil while it lubricates the valve train components. These metal or composite covers bolt directly to the cylinder heads and include gaskets that prevent oil leaks. Proper valve cover function keeps your engine oil where it belongs while protecting internal components from contamination.

Valve Cover Design and Function

Your valve covers create a sealed chamber above the cylinder heads where oil circulates to lubricate camshafts, rocker arms, and valve springs. Most covers include baffles or oil separators that prevent excessive oil vapor from entering the PCV system. Breather ports or PCV valve connections allow crankcase pressure to escape while maintaining proper oil circulation. The covers also provide access points for valve adjustments and timing belt or chain service when required.

Common Cover Problems and Warning Signs

Valve covers typically develop leaks due to deteriorated gaskets, warped sealing surfaces, or loose mounting bolts over time. Most gaskets last 80,000 to 120,000 miles before requiring replacement, depending on operating conditions and maintenance intervals. Look for oil stains on your driveway, burning oil smells while driving, or visible oil accumulation around the valve cover edges. Your gaskets work together with valve covers to maintain proper sealing and prevent costly oil loss that could damage your engine.

Why Choose Genuine INFINITI Valve Covers

Genuine INFINITI valve covers are manufactured with precise tolerances and high-quality materials that resist warping and cracking under extreme temperatures. Aftermarket covers may use inferior metals or plastics that fail prematurely, leading to expensive oil leaks and potential engine damage. Vehicles like the G37 and FX35 require specific cover designs with integrated PCV systems that only genuine parts provide reliably. Keep your vehicle running like new with INFINITI of South Bay's top-notch components.
