coolant getting into cylinder(s)
Well... I haven't started it for about 4 months. Last time I did was for about 5 minutes to test drive it after a new cat. Another time I let it file for a minute and I saw coolant dripping from where I didn't clamp the exhaust after the new cat, the stuff dripping was green tinted. I could not really tell the color of the exhaust because it was 15 degrees out and all exhaust steams at that temp. but the exhaust was "pulsating" randomly. prob when the coolant was entering.
I just did a compression test on the 3 passenger side cylinders. The rear was about 135, middle about 140 and front around 125. They all seem pretty close. could I rule out head gasket on passenger side?

No you can not. To effect a compression test the head gasket must be pretty far along. A coolant pressure test will show a blown headgasket before it will show up on the compression test. The plugs themselfs should show a coolant leak. If one plug is cleaner then the rest or even have a green tint to it that would be the bad cylinder.
I did to the test in a cold engine, it would be higher if it was warm. I had all the passanger side plugs out and they all seemed the same. One was a little moist but I'm sure it was just running rich, I tasted it. And I did a coolant pressure test and the only thing that leaked (that I could see) was the heater elbow.
Yea also make sure you open the throttle body all the way because does readings are low. Just as a reference my 3.8 showed like 110 with a cracked head so numbers like 125 are not good.
