Head Gasket - Replacement Recommendation
Bulletin 87-6-7Date Jan., '87
Ref.No. 87-056-6
SUBJECT: HEAD GASKET REPLACEMENT
MODELS AFFECTED: ALL MODELS
Production cylinder head gaskets are installed without the addition of any surface treatments or adhesion promoters. Service head gaskets should be installed without any extra sealing aids. Head gasket dressings do not increase sealing capacity and, in some cases, may actually be detrimental to the gasket's usefulness. Using a head gasket (without any extra sealant) between clean mating surfaces as well as following proper head bolt torquing procedure will yield an adequate seal in this area.
