HEAD GASKET INSTALLATION OIL LEAKS REVISED

MODELS AFFECTED: 1982 4.1L, V6 Engines

The proper installation of 4.1L V6 engine cylinder head gaskets is covered in Bulletin 82-T-84A, and as a result Bulletin 82-T-66 is no longer valid and should be removed from your Bulletin file.

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.
