NOTE
Rocker arm seats must be fully seated in the cylinder head, and pushrods must be seated in the rocker arm sockets before final tightening, or engine damage may occur.

  1. For each valve, rotate the crankshaft until the valve lifter rests on the heel (base circle) of the camshaft lobe. Position the rocker arm(s) over the push rods, then install the rocker arm seats. Tighten the rocker arm seat retaining bolts to 44 inch lbs. (5 Nm).
  2.  
  3. Final tightening of the rocker arm retaining bolt(s) is to 19-25 ft. lbs. (25-35 Nm). For final tightening, the camshaft may be in any position.
  4.  
  5. Clean the rocker arm cover and cylinder head mating surfaces of old gasket material and dirt.

  2.  
  3. Remove the valve cover(s).
  4.  
  5. Position the piston of the cylinder being serviced at the bottom of its stroke and position the camshaft lobe on the base circle.
  6.  
  7. Install a valve spring spacer tool, between the spring coils to prevent valve seal damage.
  8.  


WARNING
If the valve spring spacer tool is not used, the retainer will hit the valve stem seal and damage the seal.

  1. Install a valve spring compressor tool, under the camshaft and on top of the valve spring retainer.
  2.  
  3. Compress the valve spring and remove the roller follower. Remove the valve spring compressor and spacer.

  6.  

To install:

  1. Apply engine oil or assembly lubricant to the valve stem tip and roller follower contact surfaces.
  2.  
  3. Install a valve spring spacer tool, between the spring coils. Compress the valve spring using a valve spring compressor tool, and install the roller follower.
  4.  


NOTE
The piston must be at the bottom of its stroke and the camshaft at the base circle.

  1. Remove the valve spring compressor and spacer.
