A-Premium valve cover kit for Nissan QR25DE 2.5L — complete assembly with bolts, PCV valve & oil filler cap

The A-Premium Engine Valve Cover Kit is a complete replacement assembly for Nissan QR25DE engines that restores proper sealing and includes the valve cover, gasket, bolts, PCV valve and oil filler cap.

Designed for Nissan and Infiniti models that use the QR25DE 2.5L engine, this kit replaces worn or cracked valve covers and the associated seals that commonly cause oil leaks, burning-oil odors and smoky engine bays. The package groups all the components technicians typically replace when addressing valve-cover-related issues, so you avoid multiple trips to parts counters and reduce diagnostic time.

What exactly comes in this valve cover kit?

The kit arrives with a ready-to-install engine valve cover assembly that already houses the PCV valve, oil filler cap and spark plug cover. It also includes a new valve cover gasket and a set of valve cover bolts sized for the QR25DE engine.

• 1 x complete valve cover assembly (with PCV valve, oil filler cap and spark plug cover)
• 1 x valve cover gasket to ensure a tight seal
• Set of valve cover bolts with recommended torque steps
• Installation-ready components to replace worn parts in one service

Which vehicles and engines does this fit?

This valve cover kit is matched specifically to Nissan and Infiniti vehicles built around the QR25DE 2.5L engine. Confirm fitment by year and engine code before ordering to ensure compatibility.

• Nissan Altima 2013–2018 (2.5L Gas)
• Nissan Rogue 2014–2017 (2.5L Gas)
• Nissan Murano 2016 (2.5L FHEV full hybrid)
• Nissan Pathfinder 2014 (2.5L FHEV full hybrid) and Infiniti QX60 2014–2017

How does this kit address common engine issues?

Worn valve covers and failed seals are frequent sources of oil seepage and misbehavior in the engine bay. Replacing the entire cover and sealing components restores proper containment of oil and helps eliminate secondary symptoms like oil on ignition coils, smoke from the bay and burning-oil smells.

• Replaces cracked or warped covers that allow oil leaks
• Includes spark plug seals to prevent oil contamination of coils
• New gasket reduces risk of persistent seepage at the cover-to-head interface
• PCV valve included to maintain crankcase ventilation function

Are there installation tips or torque specs I should know?

Follow proper torque sequencing and steps to avoid overtightening and to ensure an even seal. The kit supplies bolt torque guidance in two steps and comes with all fasteners needed for a professional-quality install.

• Step 1 torque: 1.96 N·m (0.20 kg·m, 17 in·lb)
• Step 2 torque: 8.33 N·m (0.85 kg·m, 74 in·lb)
• Replace spark plug seals while coils are accessible to prevent oil fouling
• Clean mating surfaces before installing the new gasket for best sealing

Who this is for: Mechanics, DIY enthusiasts and fleet service technicians working on Nissan QR25DE 2.5L engines who need a single, complete valve cover replacement solution. If you are resolving oil leaks, coil-area contamination, or dash warning lights related to poor sealing, this kit supplies the parts required to return the top of the engine to proper working order without sourcing multiple separate components.
