I always knew something was up with my piston, especially when i saw black oil inside of the exhaust port (when I removed the headers). But now I noticed that if I unplug the spark plug wire to that cylinder there is NO change in engine sound or speed (uh-oh). My ECU never gave me any codes as to a cylinder malfunction and I always thought I had a bad valve seal, but I guess I was wrong. How can I target the problem, or see if I can get the cylinder firing again? Should I do a compression test or what?
Thanks,

P.S. Its a 89 CRX DX with a B16A swap OBD0
