industry. Image shown is an actual factory supplied picture. ***Due
to engine machining variances, seal performance may vary.***
Ever
since the big gasket manufacturers discontinued using asbestos in the
1990's, rope rear main seals have been a huge problem to the vintage
car enthusiast. The non-asbestos rope seals available from the big boys
are next to impossible to trim and do a poor job of sealing. BEST
Gasket has developed rubber replacement seals for many engines where
only rope seals have previously been available.
