Installation





1. NOTE: If the engine front cover is not secured within four minutes, the sealant must be removed and the sealing area cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness, or for four minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.

Apply sealant along the cylinder head-to-block surface and the oil pan-to-cylinder block surface.
