LEMASSON Engine Valve Covers for Nissan 4.0L V6 — Left & Right Set, Reinforced Plastic, Fits Frontier/Xterra/Pathfinder/NV

LEMASSON left and right engine valve covers for Nissan 4.0L securely seal the top of the engine to stop oil leaks and keep contaminants out.

These replacement valve covers are molded from reinforced plastic to resist heat and engine-bay stress while matching OEM fitments for a range of Nissan 4.0L vehicles. They are engineered to replace part numbers 13264-EA200 and 13264-EA210 and fit specific model years of Frontier, Xterra, Pathfinder and NV-series vans. The set comes as left and right covers and includes LEMASSON's one-year warranty and customer support.

How do these valve covers prevent oil leaks and contamination?

The covers create a tight barrier for the cylinder head area to prevent oil from escaping and to block dust and debris from entering the valve train. Their molded sealing surfaces and precise bolt-hole alignment reduce the risk of uneven seating that can cause leaks.

• Reinforced plastic resists warping under heat, maintaining seal integrity.
• Accurate OEM-style mounting points ensure proper torque distribution.
• Compatible with factory gaskets and seals for easier installation.

Will these fit my Nissan Frontier, Xterra, Pathfinder or NV van?

The set is compatible with 4.0L V6 Nissan engines across specific model years: Frontier (2005–2019), Xterra (2005–2015), Pathfinder (2005–2012), and NV1500/NV2500/NV3500 (2012–2019). Always confirm the vehicle’s year, engine size, and existing part numbers before ordering.

• Designed to replace part numbers 13264-EA200 and 13264-EA210.
• Fits the Nissan VQ-series 4.0L installation points and bolt patterns.
• Check your current cover’s part number to verify exact compatibility.

What materials and durability features do these covers offer?

Manufactured from high-quality reinforced plastic, these covers withstand typical engine temperatures and exposure to oil without cracking or deforming easily. The material choice balances durability with weight savings compared to metal alternatives.

• Heat-resistant polymer construction reduces long-term degradation.
• Impact- and chemical-resistant formulation minimizes premature wear.
• OEM-style finish for visual match under the hood and corrosion resistance.

How simple is installation and what should I expect during replacement?

Installation follows standard valve cover replacement steps: removing the old covers, cleaning mating surfaces, installing new gaskets if required, and torquing bolts to factory specifications. It’s a straightforward job for a home mechanic with basic tools or a quick service for a professional shop.

• Replace gaskets and seals during installation for best results.
• Follow vehicle manufacturer torque specs to avoid distortion.
• Inspect nearby components (PCV valve, hoses) while the covers are off.

Who is this for: Owners or mechanics working on Nissan 4.0L V6 engines who need reliable OEM-fit valve covers—especially those repairing oil leaks, replacing damaged covers, or refurbishing engine appearance. These LEMASSON covers suit drivers of Frontier, Xterra, Pathfinder and NV-series vans within the listed years who want a durable, compatible replacement with warranty-backed support.
