lots of silcon and dielectric grease
used the dielectric grease (I use the silcon caliper grease) on all plug in connections.
used silcon rtv to seal distributer cap, ran a vent tube out of the top of the cap to a high place.
seal up where the air filter hose goes to the throttle body,
extend all breather hoses, differentials and trans/ tcase, also clamp them on the fittings.
