Ok, I was having the issues with a really rough idle and up to about 2k rpm. I did a compression test on the cylinders and here is what I came up with...
Dry
1) 60 psi
2) 100 psi
3) 145 psi
4) 150 psi
5) 145 psi
6) 140 psi
I then squirted oil into the 1 & 2 cylinders and here is what I got...
Wet
1) 75 psi
2) 120 psi
I suspected the head gasket was probably blown between the 1 & 2 cylinders... I got it all ripped apart and there is no noticeable tear or break in the head gasket. The gasket actually looks cleaner between the 1 & 2 cylinders. Is it possible it was just leaking and I cant see it? The head and valves "look" fine. Monday I will be taking the head to a machine shop to have them do a valve job and clean it up. The cylinder walls also look great. They just have the cross cuts in them from honing.
Any Ideas?
Thanks,
Tom
