Hello all, don't mean to chime in, but my YJ (89, Ford TFI ignition, MC2100 carb, Nutterd'), is showing the same symptoms as cstimmons and I am very anxious to see the resolution to this problem. I had a rough idle, SEVERE blowby from the valve cover, poor fuel mileage, decreasing coolant levels, oil coated air filter, and a nice frothy milkshake for oil. I already went through the entire PCV system and replaced everything, cleaned oil baffles, etc. After doing a compression test, I found that all cylinders were around 135psi normal and 150psi with addition of some oil...with the exception of the #2 cylinder, 45psi normal and 60psi with oil. I took this as a sign that either I have valve problems or a blown HG. Does this sound like a logical conclusion? I have already pulled the head and the gasket looks good. As a forethought I ordered a reman head from Autozone, still not due to arrive until the 13th. I need my Jeep back!
