ok, so I did a compression test and found out that I have approx. 100 psi every cylinder except #6 which is 25 psi. I sprayed in a little gear oil and got it to 35 psi.

So I think that this means I have catastrophic failure of piston rings or a valve is not completely shutting. I'm researching online to see what information is available to be able to further diagnose the situation and how to fix valve if possible without tearing it down.
