Thread: Need Help Solving this engine puzzel

It is not a HOT Rod question but it is an engine question I figure you guys have torn all kinds of engines. Here is the puzzel

This is a 1997 Pontiac 3.1 engine

The engine started running real rough. Note no engine codes, great plugs wires etcetc. I took a compression reading and I found that 1 of the pistons read 30psi and the other 5 read 150psi. Thinking I had burnt valves I took the head off and I found that the valves were perfect. I then poured 6 onces of tranny fluid in the sick piston and 6 ounces of tranny fluid in a good piston in the morning I found that 1/2 of the tranny fluid had leaked into the crank case and in the good piston most of the fluid was still there. So can I asssume that the rings are shot in the sick piston. Yes/NO
