Remove the oil level indicator. Install aEN 23951valve manometeror equivalent.Start the engine.Check for slight vacuum. The vacuum level should be less than3.377-kPa (1-in-Hg).If vacuum is higher, inspect and verify that the clean airhose from cam cover to air intake is not blocked or kinked.If vacuum is in the normal range, block or pinch off theclean air hose. The clean air hose is the hose between the camcover and air intake system. Vacuum should increase on themanometer. If held too long, vacuum will be drawn through thecrankshaft seals creating a sucking sound.If vacuum does not increase, the orifice in the intakemanifold could be plugged.If there is zero vacuum or pressure, verify compression ofthe engine.If compression is normal, check for a blocked orifice at theintake manifold. Clean the orifice.
