Engine Block: Cleaning

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, 3/8 inch NPT plugs and the coolant drain plugs to the proper specifications. Refer to TORQUE SPECIFICATIONS  .
