It could be any number of things... It could be REALLY bad rings, bad head gasket, bad valve seats, weak valve springs, hole in the piston... or another dosen causes. How low is the cylinder pressure, and was there any symptoms leading up to it?

ez way to see if the problem is piston ring related is pore a cap of oil down the hole and do another comprecion check if your numbers spike up then its your piston or rings if the # dusnt change then its in the head ie valve or so on.

and for another test would be a cylinder leakage test performed on each cylinder to find out the percentage of leakage per cylinder
