Hey Lew, maybe I have the name wrong, but the springs are the very old Direct Connection dual springs that were listed for the smaller solid lifter cams & as "optional" on the old original Direct Connection purple shaft 292/509 hydraulic cam. This motor was built in 1985 & I have since changed the camshaft (fyi).


At one point I did replace two of the Isky ball/cup pushrods, which made me wonder if my replacements were accidentally the solid-lifter version (slightly longer vs. hydraulic pushrods)…..checked that & the pushrod matches the other ones.

It's just that this one adjustment screw is so much different than the others (visually). My only thought are:
a. I missed adjusting that rocker
b. That valve has a push rod too long (checked that, not it)
c. The lifter is stuck in the fully pumped up position
d. My rocker shaft is loose, so my valve lash adjustments are WAY off.


This all started tracking down valve gear noise. I double checked my rocker/valve cover clearance...no "witness marks" on valve cover baffles. I don't think I have any bent pushrods, but I will roll them all on a mirror just to be sure.

Any other thoughts?
