SITUATION

Certain areas of the US experience extremely cold climate conditions during the winter months. A small number of vehicles in the above-listed Series have experienced problems ranging from leaking or broken valve covers to complete engine failure. CAUSE

Moisture accumulating in the engine oil separator; hose to oil dipstick guide tube; or the orifice in the dipstick guide tube can freeze. When this occurs, depending on the position of the internal valve, it may either cause high crankcase pressures (stuck closed) resulting in valve cover leakage and/or breakage, or cause an oil hydro-lock condition (stuck open), which could result in engine damage. CORRECTION

Replace the crankcase vent valve, crankcase vent hoses, and dipstick guide tube.

1. Replace the oil separator and hoses (1) with the new insulated style (2).

2. If the vehicle is already equipped with the new insulated crankcase ventilation valve and hose, only replace the dipstick guide tube with the part number from the list by model below. 3. If the vehicle is not equipped with the new insulated crankcase ventilation valve and hose, replace those parts with the updated style and replace the dipstick guide tube with the part number from the list by model below.
