Preliminary Procedure Thoroughly clean the camshaft cover and mating surfaces. Inspect each component, O-rings, and fasteners, and replace as necessary.
1	Camshaft Cover WARNING: Refer to Safety Glasses and Compressed Air Warning . Procedure: NOTE: Disassemble the camshaft cover components before using compressed air. Use a rubber tipped compressed air blow nozzle to clear the oil passages in the camshaft cover. Use the compressed air to clear the primary PC port and high pressure input passages. Use the compressed air to clear the oil feed to low pressure drip rail passages. NOTE: Potential debris present in the drip rail passages will accumulate in the drip rails. Debris may or may not obstruct the air and/or oil flow through the drip rail. Ensure there is air flow through both the intake and exhaust side of the drip rail. Replace the camshaft cover if the air flow is restricted or cannot be verified, indicating a whole or partial obstruction.
