SUBJECT:
OIL PAN DRAIN PLUG LEAK
MODELS AFFECTED: 1985-1989 DE VILLES AND FLEETWOODS 1982-1989 ELDORADOS AND SEVILLES 1982-1985 RWD DE VILLES
AND BROUGHAMS
Some 1985-1989 DeVilles and Fleetwoods, 1982-1989 Eldorados and Sevilles, and 1982-1985 RWD DeVilles and Broughams 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). Parts are currently available from GMSPO.
5.
Install plug and gasket and torque to 30 N-m (22 ft.lbs.) and inspect for leaks.
