#1 has low compression. What should I do?
Did a compression test and all were around 125 except #1. It read only 95 and when i went back to double check it was not responding and going up each turn of the key. What might be wrong?

The neat thing about a leakage test (as opposed to a compression test) is that it's faster and easier to figure out where the pressure is going. If you hear air coming out of the tailpipe, it indicates a leaky exhaust valve. Air coming out of the throttle body or carburetor would point to a leaky intake valve. Air coming out of the breather vent or PCV valve fitting would tell you the rings and/or cylinders are worn.

Indeed. This is #1 & # 7 from my old motor. Take your pick.
It still went 12.4 as it was checking out with broken pistons, blown head gasket and all
