Nice day sunday, so I decided to play with the 79. Checked the compression, just to play with my new tester. ARGH! Cylinders 1-3 were around 100-110, but cylinder 4 was stuck at 60 psi. Put in a little oil, got it up to 100. My question is, do you check compression with the engine warmed up, or is a cold
(50F) check accurate?
