Default Bolts, Washers and Sealants

Clean, dry bolts with a couple drops of blue Loctite on bottom threads of bolts (Injector Housing) and thin coat of Permatex on gaskets (except when I have a gasket NOT exposed to coolant in which case NOTHING on gasket). Red Loctite on everything inside the Front Cover. Blue Loctite on Oil Pan Bolts. Nothing on Head Gasket and nothing on Plenum gasket since I have TB/Plenum coolant locked.

Actually I do not use any Loctite on my SS Allen Head Bolts (Cam Covers or Plenum). I use Aluminum Stat-O-Seal Washers on all Allen Head SS Steel Bolts installed in the Plenum and Cam Covers (including the IH Coolant Manifolds).

Aluminum Stat-O-Seal washers with molded Buna-N inner seals are much more reliable than the more common steel stat-o-seals. If the rubber portion fails to make contact all around the port, the aluminum will act as a crush washer, providing a reliable metal to metal seal. Use them to seal screws, bolts or plumbing fittings. The Buna-N seal is resistant to petroleum fuels and oils.
