Diesel Head Gasket - Revised

Number: 83-I-66 Reissue

Section: VI

Date: June, 1983
Subject: DIESEL HEAD GASKET 1978-1983 ALL MODELS USING 5.7L DIESEL ENGINES


TO: ALL CHEVROLET DEALERS

This bulletin is being reissued to correct the part number for the purple seal.

The diesel gaskets listed below will supersede previous gaskets for servicing 5.7L 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.
