<VV> compression test

[Mark Durham]

Bruce, if compression comes up by adjusting the valve lash looser, it
means you had them adjusted too tight, and you should do an adjust to
them all. All you need is 1/4 to 1/2 turn past zero lash, adjusted warm
and running. Drive the car for awhile after adjusting then recheck
compression. If there is a problem, I have seen worn valve guides to
allow the valve to not seat correctly, especially if the correct
geometry was not set up and you have a rocker pushing a valve to the
side and the guide is worn.

I have re- assembled my 64 110 engine after a "re-seal" Did a
compression check. All but two cylinders looked Ok  ( within 10 lb. of
145 lb).  #'s 3 & 5 read 0. I backed off the valve adj. on those two
cylinders, re-tested and got 160 & 175 lb.s can anyone tell me just
what this might indicate?  such as bad rings, bad valves or what?
