Sorry just found this.
Warm motor for at least 20 min and remove valve cover.
Set motor to TDC compression stroke on #1. Look at the #1 valves, the lobes should be pointing downward and the valves fully closed. The rocker arms should not be on the lobe but on the lowest part of the cam.
There are 8 valves to set and half of them can be set in this position.
From the front, set valve 1, 2, 4, 6
Rotate the motor exactly ONE turn. Check the cylinder #4 valves are both closed and the cam lobes are pointing downward.
Set valves 3, 5, 7, and 8. DONE.
How easy was that?
