Valve Clearance

WARNING: After lifters are reinstalled whether new or used, DO NOT start engine for 30 minutes, as valves may hit pistons. Lifters must be allowed to bleed down before starting engine. Turn crankshaft 2 full revolutions before starting engine to ensure valves do not hit pistons.

All models use hydraulic valve lifters. No adjustment is necessary. To check a suspect valve lifter remove valve cover and turn crankshaft clockwise until cam lobe of suspect valve lifter is pointing upwards. Using a plastic or wooden dowel push valve lifter down. DO NOT pry on lifter. Attempt to insert a .008" (.20 mm) feeler gauge between camshaft and lifter. If feeler gauge fits between camshaft and lifter, replace lifter. If feeler gauge does not fit between camshaft and lifter, lifter is okay.
