Toyota 1121331050 — Valve Cover Gasket
Overview
Valve cover gasket Toyota 1121331050 seals the interface between the cylinder head and the rocker cover on 1GR-FE 4.0L V6 petrol engines. This component retains engine oil within the valve train assembly, preventing external fluid leaks and stopping oil migration into spark plug wells. Manufactured from heat-resistant acrylate rubber (ACM), it withstands operational temperatures ranging from -40 °C to +150 °C while resisting chemical breakdown from synthetic lubricants. OEM cross-reference number 11213-31050 matches the exact profile geometry of the right-hand cylinder bank valve cover channel. Seal cross-section thickness measures 6.5 mm with an overall component weight of 85 g.
Replacement is required when oil weeping appears along the cylinder head mating surface, oil deposits collect on spark plug threads, or during valve clearance adjustments at 100000 km service intervals. Elastomer hardening and embrittlement over time compromise the sealing lip profile, leading to pressure loss and fluid seepage. Fits Toyota Land Cruiser Prado 120 and 150 series, Toyota 4Runner GRN210, Toyota FJ Cruiser GSJ15, and Toyota Hilux GGN25 vehicles produced between 2002 and 2015 fitted with 4.0 V6 powerplants. Restores factory engine sealing without requiring additional liquid sealants.
