Place the vehicle on jackstands, empty the engine oil and remove the crankshaft pulley. Reduce the vehicle and put a jack below the engine and release pressure to take off the right engine mount center bolt. Proceed to take off the engine oil dipstick, valve cover, and certain bolts of the cylinder head and oil pan followed by the timing chain case cover and check it against damage.
