Anyone familiar with a 2000 Jeep Grand Cherokee 4.0 that mysteriously leaks coolant?
New radiator, new thermostat, checked for cracked head or head gasket leaks - no issues there. Pressure on system reveals no leak. Very little pressure at radiator cap. Temps constant. No leaks under Jeep when parked. Going through quart of coolant/per week. Respond to firstname.lastname@example.org. thx!

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.
Sorry. Newbie just looking for answers. Forget the e-mail request folks. I will get my information here. BohoMark any clues about my problem? Thanks.
First thing boyd,do you smell anti freeze,at any time when you get out of jeep after it is warm?
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!
4.0 heads are known to crack
