TOYOTA 11328-17022 Timing Cover Gasket

The genuine Toyota 11328-17022 timing cover gasket (Gasket, Timing Gear / Chain Cover) is an essential component for the leak-free and reliable sealing of the engine's timing case. Specially developed for Toyota 4.2-liter turbo diesel (1HD-FT) engines, this OEM-quality part provides durable protection against engine oil leaks and the ingress of external dust and contaminants.

Technical Description and Function:

The timing cover gasket hermetically seals the timing gear housing and cover. Because the timing assembly operates under continuous oil lubrication, the integrity of this gasket is critical for maintaining proper system pressure and lubrication conditions. It offers excellent thermal and chemical resistance, withstanding synthetic and mineral engine oils as well as vibration-induced stress. The most common symptoms of wear, cracking, or deformation include oil weeping or dripping around the timing cover area, which can eventually lead to timing component wear or depleted engine oil levels.
