LEMASSON Valve Cover Set for Nissan 4.0L V6 — Left & Right Replacement for Frontier Xterra Pathfinder NV Series, Reinforced Plasti

LEMASSON Pair Left Right Engine Valve Covers are direct-fit replacement covers for Nissan 4.0L engines, sealing the valvetrain to prevent oil leaks and protect internal components.

These valve covers are molded from reinforced plastic and engineered to replace OE parts 13264-EA200 and 13264-EA210 on multiple Nissan models. They’re made to survive high under-hood temperatures and maintain a snug seal around the valve train, keeping oil in and contaminants out. The set includes both left and right covers and comes with a one-year warranty when installed on compatible vehicles.

Will these valve covers fit my Nissan model and years?

They are designed to match the factory mounting points and dimensions for specific Nissan 4.0L applications. Confirm compatibility by checking your vehicle’s engine code and existing part numbers before purchasing.

• Compatible models: Frontier (2005–2019), Xterra (2005–2015), Pathfinder (2005–2012), NV1500/NV2500/NV3500 (2012–2019).
• Direct replacements for part numbers 13264-EA200 and 13264-EA210 (also listed without dashes).
• Designed for Nissan 4.0L V6 engines—verify engine size and VIN for accurate fitment.

How do these covers protect the engine and reduce leaks?

The covers create a tight barrier over the valve train to keep oil contained and prevent dirt or moisture from entering the top of the engine. A secure seal helps preserve correct crankcase pressure and reduces oil contamination risks that can shorten component life.

• Reinforced plastic resists cracking and warping at high temperatures.
• Precision mounting points align with factory studs and bolts for an even seal.
• Prevents oil from escaping around camshafts and valve components.

What materials and durability features should I expect?

These valve covers are formed from high-strength, heat-resistant plastic engineered for automotive engine bays. The material choice balances toughness and weight savings while minimizing corrosion risk compared with metal covers.

• High-temperature reinforced plastic resists thermal cycling and engine vibration.
• Manufactured to avoid brittle failure and extend service life under normal use.
• Works with OEM-style gaskets and mounting hardware for reliable resealing.

How easy is installation, and what should I check during replacement?

Installation is straightforward for anyone comfortable with basic engine maintenance; most covers bolt on with common hand tools. Replace the valve cover gaskets and clean the mating surfaces for a leak-free finish, and torque bolts to the manufacturer’s specification.

• Remove old cover, clean gasket surface, install new gasket and cover, torque bolts evenly.
• Inspect spark plug tube seals and accessory connections while access is available.
• Recommended to replace associated seals and hardware to ensure long-term reliability.

Who is this for: Mechanics, DIY enthusiasts, and fleet owners who need a cost-effective, direct-fit replacement for worn or leaking valve covers on Nissan 4.0L engines. If your Frontier, Xterra, Pathfinder, or NV-series van is experiencing oil seepage at the valve cover, or you’re rebuilding the top end of the engine, this LEMASSON left-right pair provides a durable, warranty-backed option that matches OEM part numbers 13264-EA200 and 13264-EA210. Always verify part numbers and engine compatibility before ordering to ensure a correct fit.
