Ummmmmmmmmmm....... If you did a leak down test, the results WILL show if valves, pistons, rings, or holes in stuff are present.....
If you're relying on "most likely", that's BAD..
The results of a leakdown test done correctly is never "bad"..... "Bad" is meaningless... Where were the leaks heard? Did you remove the exhaust manifold to see if the exhaust valve is leaking? Oil cap to see if leaking past rings or through a hole in the piston? Intake manifold for the intake valve?
Post should have looked like:
I think my motor is fubar. I did a leakdown test today, the results were not good. The exhaust valve leaks like a mo fo so I can not build any pressure with the leakdown testing unit. I think there's a hole in the piston/nasty piston problems as lots of air comes out of the oil cap (air passing by the piston/ring assy..).
The leakdown test will show if any of the systems are failing. Post new results...
