Engine temps are good always.

I pressure tested the cylinders both for peak and leak down. The avg. pressure was 210 psi, leak down test was good, held for as long as I cared to wait for it. All 6 cylinders were good, all plugs showed even, good burn.

I'm posting this for interest of the forum members. Frankly I'm ready to replace the engine at this point. I'd love to hear your thoughts on what I should've, could've done. Maybe I missed something or came to a bad conclusion.

so how did the plastic bag trick work out ?
