Holy crap, I just saw those pics. That definitely looks familiar...makes me feel a little better too! So I guess the only thing that has me kinda worried still is how the engine almost stalled... and then blew all the crap out at once..lol

I sure wish there was a steady pattern to this stupid thing... so I finally got around to flushing out the distilled water, and got some 50/50 prestone back in there. When it started up after that, it took a little longer for the leak to show up. I'd say around 1-2 minutes of idling. Then after...

Nice.. that would be cool so I can compare. I think what I also need to do is dump the mostly distilled water from the cooling system and add straight 50/50 anti-freeze. When it's anti-freeze I can let it pool up in my hand and smell it... that's how I knew it was the cooling system leaking into...

A puddle from just normal engine warm-up condensation?

I should have had the head tested... The shop said they didn't see anything, so I'm guessing either they missed something or it's the block. I was really careful with the gasket and it was a pretty decent fel-pro if I remember right. I made sure that both surfaces were spotless (block & head...

Man down... get the grenades. It's about a leaky SOB. Giving it throttle seems to increase the flow-rate of the leak, so I'm thinking I'm pretty much SOL. I'm gonna let it cool and try it a couple more times. Anyone think I could run this thing for maybe a month or so (as long as the coolant...

So here's what I found. This time around the leak out the tail pipe was slower because the Jeep's on a more level surface. I was getting a drip every 7-10 seconds. After 20 minutes of idling, the drips stopped at both the weep hole and the tail pipe, however the exhaust was so hot to the touch...

Thanks for the help guys. I'm going to go let it run for awhile longer and hope to the Jeep God's it stops. What has me pretty discouraged though is the fact that the leak is faster now than before I started... Originally it was a drip every few seconds, and now it's at about 1 per second. I...

I forgot to mention... ambient temp and humidity wise: today was around 85 degrees outside during the last test period with around 7% relative humidity. Gotta love the desert

No antifreeze mixed with oil. I was thinking it was condensation left over from before as well... but I've run it over and over and got it hot, then shut it off... and everytime same thing.

No, it seems to stay the same every time. I mean, I'm sure it's going down at least a little because of the steady drip out the tail pipe... but it's definitely not noticeable by looking at the coolant reservoir. If I hadn't caught the drip out of the exhaust, I probably wouldn't have ever...

Yeah, it's definitely anti-freeze. When the motor starts and runs, after about 30 seconds to a minute, it starts dripping from the weep hole in the muffler then the tailpipe soon after. At first I was hoping to God that it was just condensation from sitting, but even after running the engine for...

So I just finished the head and everything... and coolant still drips from my exhaust. When I had the head off, I could actually see where it had been leaking from the water jacket holes to the cylinders on the back 2. I had the head milled by good shop, cleaned the holy crap out of the gasket...

So now that it runs for more than 5 seconds, the trouble codes finally come through and tell me about all the sensor errors indicating the previous vacuum leak at the intake manifold. How helpful! Good thing I bought the stupid OBD II scanner since it cost more to RENT than it did to buy...

I never use air tools for this kind of thing, mainly because my tool collection isn't quite what it should be anymore...lol It looks like the first time around, the rear dowel slipped out before I had any bolts snug. This time, since I couldn't fit my head down in there to see, my girlfriend...

Mopar t's...lol. The wonderful Jeep dealer finally graced me with an intake manifold... and it even went back together with no snapping sounds this time. I sure wish Edelbrock or someone made a decent after-market intake for these motors, because I bet it would be cheaper than what I just paid...

How right you were about the vacuum leak... The snapping sound I heard wasn't quite what I thought (the manifold snapping into place over the dowels). The noise was actually the manifold cracking and breaking a nice large piece off right at the flange. Nice catch on the vacuum leak. I thought...

Thanks for the info. I'll check all the vacuum hoses and the manifold again. I could have sworn that when I started tightening that intake manifold, I heard both the front and back snap into place over those dowels... kinda freaked me out at first because I thought it was a bolt breaking. Back...

This is the first Jeep I've worked on and I'm still pretty new to these things, so any help anyone can offer would be much appreciated. I just bought a 1999 Jeep Cherokee Sport with the 4.0 Inline Six for my girlfriend, only to find out the head gasket was leaking at the water jacket a few days...
