Head Gasket - Replacement Recommendation
Bulletin 87-6-7
Date 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. This bulletin is for information only.
