Thoroughly clean the oil pan and engine block gasket surfaces.
Use compressed air to clean the following:
– Gallery at the oil filter adaptor hole.
– Front and rear oil gallery holes.
– Feed holes for the crankshaft main bearings.
Once the block has been completely cleaned, apply Loctite PST pipe sealant with Teflon 592 to the threads of the front and rear oil gallery plugs. Tighten the 1/4 inch NPT plugs to 20 N.m (15 ft. lbs.).
Tighten the 3/8 inch NPT plugs to 27 N.m (20 ft. lbs.) and the coolant drain plugs to 34 N.m (25 ft. lbs.).
