# ENGINE OIL LEAKS (TIGHTEN OIL FILTER ADAPTER)

#### Model and Year: 1989 CAVALIER, CORSICA, BERETTA WITH 2.8L ENGINE

Some 1989 Cavalier, Corsica and Beretta models produced with a 2.8L engine (VIN Code W) may experience an engine oil leak at the oil filter adapter. If diagnosis indicates the leak is from a loose oil filter adapter, the adapter retaining bolt should be tightened to 60 N.M (45 lbs.ft). It is not necessary to replace the adapter gasket unless it is damaged.

Use appropriate labor time operations.

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.
