If you feel the push rod tightening against the spring, you are already
taking up the slack. This guess or feel is probably why 2 turns is the
recommendation. The actual working range of the lifter is close to 1/4".
If you can't wiggle the push rod it is tight enough. Another turn is
adequate.

Subject: Hydraulic Lifter Week

I think lifters are a timely subject because they haven't
been covered super well, at least in the past five years
of archive searching I've done.  Dennis Haynes (as usual)
posted a good procedure in April of 2005 but it assumes
you can find zero clearance.  (see below)

With solid lifters, it's pretty clear where you are because
nothing moves.  If you are looking for zero clearance,
you just wiggle the rocker back and forth while slowly
tightening the adjusting screw.  When the rocker stops
moving, that's zero clearance. Duh, right?

The problem with the lifters that I've been trying to
adjust (and maybe they're worn) is that the springs in
the lifters are so weak that when you wiggle the rocker
back and forth it is very easy to compress the lifter spring
slightly.  I am unable to reliably say where zero clearance
is because of this.  The lifters don't feel hard, but springy.

Any ideas, anyone?

I was planning on driving it around for a while.  Being
paranoid, I'm afraid they may be adjusted too tight and
I'll burn a valve!
