A-Premium QR25DE Valve Cover Kit for Nissan 2.5L – Black with Gasket, PCV & Bolt Set

A-Premium's complete QR25DE valve cover kit replaces the worn rocker cover and seals to stop oil leaks and restore a clean, reliable engine bay for Nissan 2.5L QR25DE engines.

This all-in-one assembly includes the valve cover with installed PCV and oil filler cap, a new valve cover gasket, spark plug seals, and the correct bolt set so you can address common QR25DE issues without hunting parts. Built to match factory fitment for Nissan Altima, Altima Hybrid, Sentra SE-R, Rogue and Rogue Select model years listed, the kit focuses on sealing failure points that often cause oil seepage, burning-oil odors and ignition problems.

How does this valve cover kit stop oil leaking and engine bay smoking?

The kit replaces the valve cover and all soft seals that commonly deteriorate: the perimeter gasket and spark plug well seals. Replacing these components restores proper sealing under the cover, preventing oil from seeping onto ignition coils and hot engine surfaces where it can burn or smoke.

• Includes an OE-style valve cover engineered for QR25DE fitment.
• New valve cover gasket seals the cover bottom to the cylinder head.
• Spark plug sealing rings prevent oil from entering plug wells and fouling coils.
• Pre-installed PCV and oil cap maintain proper crankcase ventilation and sealing.

Will this kit fix misfires or burning-oil smells on my Nissan?

If oil is contaminating spark plugs or ignition coils, replacing the cover and seals often eliminates misfire symptoms and the burning-oil odor. This kit targets those exact failure points but remember to inspect coils and plugs for damage and replace them if oil has already compromised electrical components.

• Designed for plug-well isolation to reduce coil and plug fouling.
• Helps remove oil-related ignition misfires when paired with coil/plug inspection.
• Proper bolt torque sequence included to ensure even sealing pressure.
