OIL PAN DRAIN PLUG LEAK (REPLACE DRAIN PLUG)

VEHICLES AFFECTED: 1982-85 D, 1985-89 C, 1982-89 E/K

Some 1985-1989 DeVilles and Fleetwoods, 1982-1989 Eldorados and Sevilles, and 1982-1985 RWD DeVilles and Broughams with 4.1L or 4.5L V-8 engines may experience an oil pan drain plug gasket leak. A metal burr may have been left around the drain plug hole on the oil pan during manufacture. This will result in a torn or damaged gasket causing a leak. When an oil pan plug leak is suspected, or during an oil change, check the gasket for a tear. If the gasket is torn, use the following repair procedure:

1. Remove drain plug and the gasket. (If gasket stays on plug, remove and inspect).

2. Install the plug only, without the gasket, back into the pan. Tighten to 25 N-m (18 ft. lbs.). This will flatten the burrs on the pan.

3. Remove plug.

4. After inspecting gasket, replace if torn or damaged (P/N 14090908).

5. Install plug and gasket and torque to 30 N-m (22 ft. lbs.) and inspect for leaks.
