Only the 3.3L engines have valve lifters. The valve train includes roller tappet assemblies, aligning yokes and yoke retainer.

Roller tappet alignment is maintained by machined flats on the tappet body being fitted in pairs into six aligning yokes. The yokes are secured by an alignment yoke retainer.

  1. Remove the cylinder heads and intake manifolds from the engine to gain access to the tappets.
  2.  
  3. Loosen and remove the three retaining bolts, then remove the yoke retainer from the camshaft valley. Remove the six aligning yokes as well.
  4.  

If the tappet or bore in the engine block is scored, scuffed, or shows signs of sticking, have the bore reamed to the next oversize and replace the lifters with oversize tappets.

  1. Use the special tool C-4129 or a similar tool (even a magnet can help remove the lifters) to remove tappets from their bores. If all tappets are to be removed, identify the tappets to insure installation in their original location.
  2.  


WARNING
The plunger and tappet bodies are not interchangeable. The plunger and valve must always be fitted to the original body. It is advisable to work on one tappet at a time to avoid any mixing up of parts. Mixed parts are not compatible. Do not disassemble a tappet on a dirty work area.

To install:
  1. Lubricate the tappets with clean engine oil.
  2.  
  3. Install the tappets in their original positions.
  4.  
  5. Install the aligning yokes to the tappets.
  6.  
  7. Install the yoke retainer and tighten the retaining bolts to 9 ft. lbs. (12 Nm).
  8.  
  9. Install the cylinder head and the intake manifolds to the engine block.
  10.  
  11. Start and operate the engine. Warm up to the normal operating temperature.
  12.  


WARNING
To prevent damage to the valve mechanism, the engine must not be run above a fast idle until all of the hydraulic tappets have filled with oil and become quiet.
