When we did the leakdown test I pulled all the plugs and 3 were oil soaked. Now we did the leakdown on cylinder #3 and it was losing about 20% of the pressure. We bumped the engine over till we felt compresion on that hole......and he said there wasn't enough to put out a candle. Hooked up the leakdown tester and slowly increased the pressure to 100psi. The other guage read about 80psi. We determined it was the rings by listening in the throttle body, exhaust, under the valve cover, and then looked in the antifreeze for bubbles. It was a loud hissing noise...exhaust was quiet...intake he said he heard a little bit but was probably just the echo from the rings leaking. There were no bubbles in the radiator so head gasket was good. When I pulled the plug some oil came out of the hole....... Well i just want your opinons as to weather it could only be the rings. We didnt even bother doing the rest of the cylinders since the plugs looked the same as #3.
