[Chevelle-list] Valve Seal Replacement ?

[Rick Schaefer]

  Thanx all.   I had to search all over town for the correct seals.   City
of 100K with how many chevy/gmc pickups and no one stocks the O-Ring seals.
Well almost no one.    I did 1 cylinder just to get the hang of it & frankly
it was pretty easy.    I took a bit of time to get the hang of the  Lisle
Valve Spring Tool but its really simple to use.   I had to spend time with
Mom today but I'll finish in the AM.

BTW - Speaking of valve adjustment:   Is 1/4 turn after slop is out of
pushrod/rocker enough of a preload.  Hydraulic roller lifters.
