Well, I looked in the Technical section for the Valve Adjustment thread, but could not find it.

I wanted to add these two tips to the thread:

Tip #1:  Having the right kind of feeler gauges really simplifies this job.

I bought one of each size of the Motion Pro Tappet Feeler Gauges.  You need one of each size offered (a total of three items) to do the job properly:





Here is a pic of one of these nifty feeler gauges in action:




The job is a lot easier when using these special feeler gauges.  I feel as if I was setting the clearance too loose when I was using straight blade feeler gauges.

Tip #2:  To prevent a false "no-go" condition when trying to insert a feeler gauge while checking valve clearance, you need to ensure that the rocker arm's tappet adjustment screw is not resting on top of the valve stem.  I do this by gently "levering" the outboard end of the rocker arm upward using a screwdriver:




After moving the rocker arm, you can carefully remove the screwdriver.  The rocker arm should stay in the lifted position.  If you have the clearance, you can now easily get the feeler gauge into the gap.

IHTH someone!

New feeler gauges often have a bit of a stamping burr on the edge that catches. Just polish the edge up on a wheel or with very fine abrasive paper.
