Product Description
Brand-new front timing chain cover crankshaft seal for 1985-1987 Buick Grand National, Turbo Regal, 1987 GNX and 1989 Turbo Trans Am with original stock GM timing chain cover.
This updated "lip-style" seal replaces the old, obsolete, factory "rope-style" seal.
We recommended this seal for use with stock GM timing chain covers only, as this seal may not be compatible with certain aftermarket timing chain covers.
