<VV> Noisy lifter

Them's fighting words!

And after a good hot oil bath I'm ready for a fight!   ggg

Sure, cold is the shop manual and GM way to do it. But who listens to 
those experts?   ggg

Then there is the 3 threads and you are done crowd. Or pick another 
number. These are the threads exposed on the stud after tightening the nut.

The only purpose I find in adjusting hot is locating stuck lifters. When 
one doesn't pump back down to quiet, there is the problem. Well, that 
and the lovely hot oil treatments for my skin...

Back in the 70s and 80s I worked on a lot of high miles no care engines 
for everyday drivers. This is when the "must adjust hot" theory came 
about, to find problems, or just to make them work. many a Corvair left 
with a "solid" lifter adjusted to just near quiet. But at least it 
didn't leak oil.

Oh, and adjusting them hot usually got the push rod to seat properly, 
which is the only bugaboo for people trying to adjust them cold/not running.

And one more thing if you order now - you can really see too high an oil 
pressure when adjusting them hot. Quite surprising how much oil can come 
out of a push rod with a stuck pressure relief valve.

Adjusting cold is so anti-climatic. No pain, just a running engine.
