Timing Cover: Description and Operation
Timing Chain Case^ The timing chain case is formed by the front chain cover and rear chain cover, both made of aluminum die casting. This two-piece chain case design helps reduce noise.
^ Sealing materials used between the engine block and rear chain cover are an O-ring, metal gasket, and liquid gasket. Between the front and rear chain covers, liquid gasket is used to prevent oil from leaking out.
^ A fluorocarbon resin oil seal is used at the crankshaft opening in the front chain cover.
