Well, Dude, when you include a email address in your question, it reeks of some Nigerian Princes millionaire looking to add to his list of potential suckers. This is the way to correspond. Not by personal email.

The 4.0 engine is about as bullet proof as thy come. What were the compression test reading when you had it tested?

In my opinion,when you done the pressure test,with this small of leak,you would have to wait,a good while before it would show a leak down,and in my personal expereance,have delt with the same problem on a cherokee,it was a very small micro pin hole in the intake gasket,that only leaked while driving it,and engine heat would dry it up without even a trace of it,i replaced intake gasket and no more mystery leak.

T_S_T. I think you hit the nail on the head. That makes perfect sense. Boyd, do you ever get the smell of anti freeze?

I have never smelled anti freeze. Even up under the hood. We will replace the intake gakest. I am convinced it is turning to steam from someplace. I love this old Jeep, even w/ 235K it still runs very well. THANK EVERYONE for your input. I really appreciate it. I'll let y'all know!

BoHoMark, I will get the compression readings. They seemed ok to me, but I am not as knowledgeable as you guys. Thanks!
