These LEMASSON replacement covers are molded from reinforced high-temperature plastic and engineered to fit the same bolt pattern and sealing surfaces as the original 13264-EA200\/13264-EA210 parts. Installing new covers can reduce oil seepage, make engine bays cleaner, and help preserve the condition of ignition components and hoses beneath the covers.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these valve covers stop oil leaks on 4.0L Nissan engines?\u003c\/h3\u003e\n\u003cp\u003eThe LEMASSON covers recreate the factory sealing surface and accept standard gaskets to re-establish a tight barrier between the head and the cover. With proper gasket installation and torqueing, they prevent oil from weeping onto spark plug boots, coils, and wiring. They also resist warping under normal engine temperatures to maintain a stable seal over time.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eExact bolt-hole alignment matching OEM 13264-EA200 and 13264-EA210.\u003c\/li\u003e\n  \u003cli\u003eReinforced plastic resists heat-induced deformation.\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with original or replacement valve cover gaskets.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these covers fit my Nissan model and year?\u003c\/h3\u003e\n\u003cp\u003eLEMASSON lists compatibility with Nissan Frontier (2005–2019), Xterra (2005–2015), Pathfinder (2005–2012) and NV1500\/NV2500\/NV3500 (2012–2019) that use the 4.0L V6 and the OEM part numbers 13264-EA200 \/ 13264-EA210.
