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

  1. Position the camshaft so the base circle of the lobe faces the cam follower of the valve to be checked
  2. Using the special tool, slowly apply pressure to the cam follower until the lash adjuster is completely collapsed
  3. Hold the follower in this position and insert the proper size feeler gauge between the base circle of the cam and the follower
  4. If clearance is excessive, remove the cam follower and inspect for damage
  5. If the cam follower is intact, measure the valve spring assembled height to be sure the valve is not sticking
  6. If the camshaft dimensions are to specifications, remove, clean and test the lash adjuster
  7. Reinstall the lash adjuster and check the clearance; replace damaged or worn parts as necessary
