CAUTION: To prevent oil from entering the PCV system during air-powered oil fills, the closure hose should be disconnected from the oil fill pipe (6A868) and positioned away from the oil source. Cover the hose port with a shop towel to prevent oil from spilling onto the engine during oil fill. Reconnect the closure hose after the oil has been filled to the proper level.
Fill the crankcase with the proper grade and quantity of engine oil. Check oil level. Start the engine and operate it until it reaches normal operating temperature, then check for leaks.
