Is your timing cover gasket failing? Timing cover protects the timing belt or chain that connects the camshaft to the crankshaft. The cover ensures that dirt and grime from the outside world don’t enter into the engine itself, and the timing cover gasket is there to complete the air-tight seal. As time goes by, the gasket begins to dry out and shrink, cause the timing cover gasket to fail.
