In section 2) Common Sense and Assembly Sequence in the "Builders Guide" found at www.modelaengine.com, there is a paragraph addressing how to check for oil system leaks.

The paragraph found in the "Builders Guide" is pasted below.

It is important to verify that there are no open passages or leaks from the pressurized oil system. When the short block is assembled, remove the lower bolt (A-21111) from the Cylinder timing gear cover side (A-6017) and apply 40 PSI air pressure while checking for leaks at the rear main oil galley plug, the castle nuts for main bearings, the interface between the cylinder block and flywheel housing, the rear main seal, and the interface between the rear main bearing cap and cylinder block.
