Run it a little first to pump up the lifters as much as they will go. Then
try readjusting.

Subject: Help!, Something funny with Valve adjustment
Hi All:
I am in the middle of adjusting my valves on an 82 Vanagon and have run
into a problem. Advice and wisdom sought.
Before I begin let me state that I have read (but maybe not understood)
the following on adjusting valves for an air-cooled Vanagon:
Bentley's,
Haynes,
Muir's,
Stan's ShapingUp page
(http://williamwareagency.com/forsale/stanvan/shapingup.htm),
and
Boston' Bob's Hydraulic lifters article
(http://www.bostonengine.com/articles/hydraulicll.htm).
I decided to use the 0.006 method of adjusting the valves as In thought
I understood this procedure.
On a good valve, I adjust the lash to 0.006 and then test the clearance.
I can just place a 0.006 gauge between the valve and adjustment screw,
but cannot fit a 0.007 gauge. In addition after adjustment I can just
slightly move the rocker back and forth.
Now on some of the valves (two so far) I have the following problem. I
adjust the lash for 0.006, but when I test it with the 0.006 feeler, I
cannot fit the feeler between valve and adjustment screw. However, I
have no problem with the 0.007 or 0.008 in blades. If I back off on the
adjustment screw a little bit, the 0.006 blade will fit, but again so
will the larger sizes. On these valve the rocker will not move after
adjustment. When the larger feeler blades fit I am wondering if I am
just compressing the lifter due to air. The van sat for 24 hour since I
took off the valve covers. The PO had torqued the jam nuts down so tight
that three of them stripped and I had to find new ones before continuing
with adjustment.
Would it be better if I tried another adjustment method? Would Stan's 1
turn clockwise be a better solution?
Puzzled in paradise :-(
