Motor's Coming Out..... :(

I just did the head gasket on it, since there was a variation in cylinder pressure between #2 and #3 cylinder (#1 - 170, #2 - 155, #3 - 110, #4 - 170) originally, no rust in the cylinders at all....... After #1, 2 , and 4 were all 165, #3 still 110........ I just soaked #3 in Marvel mystery oil for the past 3 days, still no change....... So, it's looking like the motor is coming out to get a new set of rings........ Just hoping there's nothing wrong with the piston itself.....

Found out the top compression ring in #3 cylinder has lost its tension........ Gonna give the cylinders a light hone and re-ring all 4 cylinders......

AAANNNDDDD......... #3 cylinder still has lower compression than the other three cylinders!!! Now I'm at a loss as to what the issue could be.......

Looks like I'm just gonna drive it this way till I do an engine swap (still up in the air as whether to do a 4 cylinder turbo swap or a V8),,,,,,

I pulled the head again to check for a stuck valve......... Pulled both intake and exhaust valves out, nothing out of the ordinary, other than that the exhaust valve was a little tight coming out....... cleaned everything up, put it all back together...... Now I have 20 psi in #3 cylinder!!!!! Could I possibly have a bad lash adjuster, like stuck open, holding a valve wide open????

Pulled head and sent to a machine shop to pressure check it...... #3 exhaust valve seat is toast!!! Picked up another head (rebuilt) and replaced it today...... Car runs like new again!!! Finally solved the issue......
