Nissan Valve Covers - Genuine OEM Parts
At Empire Nissan of Bay Ridge we understand the importance of keeping your valve covers in good condition. These aluminum or composite housings protect your engine's valve train components while containing engine oil within the cylinder head area. Valve covers also house the PCV system and various sensors that monitor engine performance. When valve covers develop leaks or cracks, oil seepage can damage other engine components and create safety hazards from oil dripping onto hot exhaust parts.
What Valve Covers Do for Your Engine
Valve covers seal the top portion of your cylinder head, preventing oil from escaping while allowing proper ventilation through the PCV system. The gasket between the cover and cylinder head creates an airtight seal that maintains proper oil circulation. Modern Sentra engines feature integrated coil packs and wiring harnesses mounted directly to the valve cover. These covers also provide access points for valve adjustments and timing chain maintenance. The design includes baffles that prevent oil splash from interfering with valve operation.
Common Valve Cover Problems and Timing
Valve covers typically fail due to gasket deterioration, warping from overheating, or cracking from age and thermal cycling. The rubber gaskets become brittle and lose their sealing ability after 80,000 to 100,000 miles of normal driving. Oil leaks around the perimeter indicate gasket failure, while cracks in the cover itself require complete replacement. Maxima owners should watch for oil pooling on top of the engine or burning oil smells during operation. Delayed replacement can lead to oil contamination of spark plugs and ignition components.
Benefits of Genuine Nissan Valve Covers
Genuine Nissan valve covers feature the exact mounting points, sensor provisions, and ventilation systems designed for your specific engine. The materials resist warping and cracking better than aftermarket alternatives, providing longer service life and better sealing. Original equipment covers include all necessary hardware, gaskets, and seals for proper installation. Aftermarket covers may not accommodate all factory sensors or PCV components, leading to check engine lights and performance issues. Our genuine parts ensure compatibility with existing wiring harnesses and mounting brackets.
