Engine Block - Cleaning






CLEANING

Thoroughly clean the oil pan and engine block gasket surfaces.

Use compressed air to clean:

- Gallery at the oil filter adaptor hole
- Front and rear oil gallery holes
- Multiple Displacement System (MDS) oil gallery holes in the valley
- Oil feed holes for the crankshaft main bearings

Drilled and tapped holes should be free of debris upon assembly.

Once the block has been completely cleaned, apply Loctite(R) PST pipe sealant with Teflon 592 to the threads of the front and rear oil gallery plugs and coolant drain plugs. Tighten the oil gallery 1/4 inch x 18 NPT plugs to 20 Nm (15 ft. lbs.). Tighten the coolant drain 1/4 inch x 18 NPT plugs to 34 Nm (25 ft. lbs.). Tighten the 3/8 inch x 18 NPT plugs to 27 Nm (20 ft. lbs.).
