There has to be some trick mechanics use to get valve
adjustment correct. I spend hours and hours and hours and
never get them spot on. I'm trying make the final adjustments
after break-in driving 200 miles on my reconditioned rocker
arm/shaft assembly.
I use the Bentley method- for example: Rotate fan until
valves 10 and 12 are fully open. Set gap of valves 1 and 3.
Etc, etc until all valves are gapped to .010"
So I repeat the procedure to insure I did it correctly.
Nope! Some valves were out of .010" spec. So I reset them all.
Repeat the procedure to make sure I got it right THIS time.
Nope! different valves now out of .010" spec.
I seem to have an eyeball problem determining exactly when
a valve spring is fully compressed. The two full open valves
never have the same amount of downward movement of the springs.
Why is this?
My car runs pretty good but I would like to master valve adjustment and have my valves on spec.
All suggestions welcome.
