The following is a revised rear main seal installation procedure for the engines listed above.
REAR MAIN SEAL INSTALLATION
1.
Clean the seal groove in the block and/or gap as necessary.
2.
After cleaning the groove, apply a THIN even coat, about two drops of bonding adhesive, GM part #1052621, Loctite 414, Fel-Pro 361
(Mighty Seal), or equivalent over the entire seal surface of the groove.
3.
WITHIN ONE (1) MINUTE install the seal using service manual procedures. (After one minute the adhesive begins to cure and loses its
bonding ability).
It is important to remember that most adhesives have a shelf life of about one year. However, the adhesive is considered usable if it flows freely from the
container.
The above procedure should also be used on all PAST model diesel engines which utilize a rope type rear main seal.
