This timing cover gasket seals the joint between the timing cover and the engine block, preventing oil leakage from the front of the engine. It sits between the cover and the block, protecting the timing chain or gears from contamination and retaining lubricating oil. A degraded gasket allows oil to weep past the cover, leading to low oil pressure and potential contamination of the belt or chain. This part is manufactured by AGCO to match the original seal groove geometry, ensuring the cover seats correctly without over-compression. On reinstall, clean both mating surfaces and apply a thin bead of sealant to the gasket channel if specified by the engine service manual.
