ISSUE:

Oil may be forced through the engine PCV closure system into the intake manifold when refilling the crankcase using an air powered oil delivery system. This may occur if the nozzle of the oil delivery system is directed toward the PCV closure port. Oil entering the closure hose/intake manifold may be drawn into the cylinders during start-up creating hydrostatic forces on the pistons, connecting rods and crankshaft. These fluid forces can cause engine part damage and possible engine "no-runs".

ACTION:

To prevent oil from entering the PCV system during air powered oil fills, the closure hose should be disconnected from the oil fill pipe 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.

CAUTION:

CARE SHOULD BE TAKEN TO DIRECT THE OIL CONTROL NOZZLE AWAY FROM THE CLOSURE HOSE PORT IN THE OIL FILL TUBE DURING OIL FILL.
