DIESEL HEAD GASKET INFORMATION

The diesel gaskets listed below will supersede previous gaskets for servicing 5.7 liter diesel engines. These head gaskets are the same gaskets currently recommended for use with .030" oversize pistons and will now be used for all applications. The use of these gaskets on standard engines should prevent the possibility of loss of compression due to the gasket sealing ring "falling" into the combustion chamber. This supersession will also affect appropriate gasket kits.

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.
