<VV> valve adjustment - DIY in about an hour or less ?

I did them hot once, after paying a Chevy dealer to adjust them on a cold 
New York November day while I was at work.

It seemed so easy to have them do it while I was working and just pick her 
up after work, and save me the hassle, and get it done right by a dealer 
(back when it was it wasn't a museum piece).

When I picked her up I thought it sounded noisy and rough, but the shop 
manager assured me it would warm up.

So I started my 40 mile ride home as he closed the shop.

The car got worse and finally died on the side of the LIE about 6:30 PM

I did a "cold" adjustment of the valves myself, in a snowbank, on my back, 
in the dark (November)

Then after she was running OK, I did it again "hot" adjustment and it really 
was not that hard.

Took about an hour or less (cleaning up oily hands in cold snow took most of 
the time !), and I drove home without a problem.

In the morning, I brought her back to the dealer (Wantagh Chevrolet, Sunrise 
Highway, Long Island), and he said, "It sounds fine to me" !
Yeah, I'm sure it did ;>}) !

Always a good skill to have so DIY really paid off since I knew how to do it

Sure if all parts are working correctly, but hot is the only way to set
those stuck lifters to operate as solid lifters. It also points out which
lifters are not working correctly. And also what tapping is not caused by
misadjustment of lifter nut (worn guides, etc).

It also really shows excessive oil pressure problems!

But, I really like to set new engines cold, just like GM did on the
assembly line. And I do it cold after an o-ring job. I just do it hot now
when there is a problem that needs troubleshooting.

I started working on Corvairs when the hot method was being preached, so I
did it for all engines I worked on. If you think hot oil was a problem,
that hot muffler was way worse! ggg    Plus the fumes in the garage in

Cold is easier on your body and cleanup of the floor.

Valves are adjusted COLD. as per the shop manual. Doing it hot and running
is masochistic.
The only variance I've used, is setting each cylinder to TDC, and adjusting
that cylinder, and moving on to the next.
