OIL FILTER ADAPTER LEAKAGE REPLACE SEAL/FILTER ADAPTER

MODELS AFFECTED: 1989-1990 DE VILLES, FLEETWOODS, ELDORADOS, SEVILLES, AND ALLANTES

This bulletin supersedes bulletin T-89-122 which should be discarded.

Some 1989 or early production 1990 DeVilles, Fleetwoods, Eldorados, Sevilles, and Allantes equipped with the 4.5L V-8 engine may experience oil leakage in the area of the oil filter adapter. While there are several potential sources of oil leakage in this area, if diagnosis reveals that the leak occurs at the junction of the oil cooler lines and adapter, further diagnosis is indicated.

The cooler lines are sealed at the filter adapter with 0-ring seals designed to seal with a maximum line nut torque of 17 N-m (12 lbs. ft.). If seal damage is evident, the leak may be repaired with seal replacement. If the oil leak is not eliminated with new seals and a maximum 17 N-m (12 lbs. ft.) cooler line nut torque, an improved oil filter adapter may be installed.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
