Procedure
- Position the camshaft so the base circle of the lobe faces the roller finger follower of the valve to be checked.
- Using Valve Spring Compressor T95T-6565-A, slowly apply pressure to the roller finger follower until the lash adjuster is completely collapsed.
- Hold the follower and insert the proper size feeler gauge between the base circle of the cam and the follower.
- Remove the roller finger follower and inspect for damage if clearance is excessive.
- If follower is intact, measure valve spring assembled height; then check camshaft dimensions against Camshaft Lobe Lift specification.
- If camshaft meets specifications, remove, clean and test the lash adjuster.
- Install the lash adjuster and check the clearance; replace damaged or worn parts as necessary.
