Compresion Issues, Long Post

[Gravy]

Can't do a warm comp test atm, exauhst mani is off for the new one, gasket is en-Rout and valve cover is off. Tomorow i'm going to set the engine to TDC and look around a bit to see what i find out, and where to go from there. Gona finish preping the exauhst

Thanks for the post, i have a 80 gallon tank of air compressed at 120 psi in the garage, so i should be good for a leak down test. I'll check to see if work has one tomorow, if they do i can rent it for free. If it's a bad ring//piston how can you tell it's leaking then? Losing presure with no sign of where it's going?
