Valve Clearance: Testing and Inspection
Valve Clearance Check
1. Remove the left hand valve cover. For additional information, refer to Valve Cover.
2. Remove the right hand valve cover. For additional information, refer to Valve Cover.
3. CAUTION: Rotating the crankshaft in a counterclockwise direction may cause engine damage. Crankshaft journals are directionally machined.
Rotating the crankshaft counterclockwise can raise burrs on bearing surfaces, reducing engine life.
CAUTION: Camshaft lobes must be 180° away from each valve shim or valve clearance measurement will be incorrect.
Rotate the engine clockwise to position the camshaft lobe away from the shim surface.
4. Using the feeler gauge set, measure the clearance between the camshaft and the shim surface. Record and check the readings. Adjust the clearances
as necessary. For additional information, refer to Adjustment.
