  6.  
  7. Zero the dial indicator against the end of the camshaft, and then push the camshaft back and forth and read the end play. If the end play is beyond the service limit, replace the cylinder head and recheck. If it is still beyond the service limit, replace the camshaft.
  8.  
  9. Loosen the camshaft holder bolts two turns at a time, in a crisscross pattern. Then remove the camshaft holders from the cylinder head.
  10.  
  11. Lift the camshafts out of the cylinder head, wipe them clean, and then inspect the lift ramps. Replace the camshaft if any lobes are pitted, scored, or excessively worn.
