Before you start
- Each affected hydraulic lash adjuster must be collapsed after reinstallation of the cam follower and then released prior to any rotation of the camshaft
Procedure
- Position the camshaft so the base circle of the lobe faces the cam follower of the valve to be checked
- Using the special tool, slowly apply pressure to the cam follower until the lash adjuster is completely collapsed
- Hold the follower in this position and insert the proper size feeler gauge between the base circle of the cam and the follower
- If clearance is excessive, remove the cam follower and inspect for damage
- If the cam follower is intact, measure the valve spring assembled height to be sure the valve is not sticking
- If the camshaft dimensions are to specifications, remove, clean and test the lash adjuster
- Reinstall the lash adjuster and check the clearance; replace damaged or worn parts as necessary
