newbie form pa with a crazy coolant leak!!

Hi everyone,
I bought my very first Jeep about 3 weeks ago and I love it so far!
It's a 1988, 4 cyl, 5 spd with 77,000 miles.
It's pretty clean for the year (I think) which is one of the reasons I got it.
The issue: The person I bought it from told me there was a slow coolant leak which he had not been able to locate. I drove the Jeep for about a week while keeping an eye on the reservoir level and I noticed the leak is coming right out surface of the engine block! right out of the metal right below the exhaust manifold , so I assume it's a crack??
Is this fixable with some kind of an epoxy or JB weld?
The leak is slow,/ I may loose about a quart of coolant in 3 weeks +-.
The engine runs good, there's no smoke, or overheating.
I'm a little concerned about this because I have never seen anything like it before.
The other issue is that the Jeep Sputters when engine is cold. Runs good after is warmed, BUT after is warm, the engine idles a little high. I did a tune up (plugs,wires, cap, rotor) and it helped a little.
I appreciate any help you guys can give me!

Hmm. My first thought was a freeze plug maybe, but it sure does look like a crack doesn't it. That is interesting.

I've heard of people fixing cracks on blocks by welding, but I wouldn't trust it, from what I know I don't think there is a way of fixing a cracked block, maybe someone more knowledgeable than me will chime in, if not well it sucks....

Edit : I was looking at the picture and it could be your water pump leaking and splashing a weird pattern on the block, try cleaning it up and look at it leak while the engine is running.

I searched the topic around and some people fix cracks by doing "metal stitching" but it seems pretty involved. That's why I'm hoping there's a simpler way.
I did clean the area and watched closely and that area just starts getting wet. No splashing from water pump...

That sucks, has to be crack in the block. Be careful, just a small amount of antifreeze can kill any animal or pet. Give this stuff a try, it MAY work but I definitely wouldn't trust it to be a permanent fix. If you can't find any at a store around you I have a unopened package I can send. I paid $10 for it at a parts house and can ship to you for $13 if you want. I used some to "patch": a exhaust leak and it worked ok for a little while till I fixed it. http://www.permatex.com/products/Aut...r_Compound.htm

Drain the coolant and remove the water pump. You may be able to see the crack from the inside if it is a crack. You may be able to JB Weld it from the inside. I'd throw a new water pump and gasket back on. Here's what you'll see with the water pump off..

Burnermans idea seems like a pretty good one....try it first, a new waterpump should only be about $40.

If it is cracked, Moroso makes Block Seal that works amazingly well. Just follow the directions. A lot of racers, myself included, have used this on race motors with no issues. Just follow the directions exactly. Do NOT get the block filler. It is for race only. Its like filling your block with ceramic. Good if your just going 1/4 mile, bad if you like to drive it.

If it has tracks, tires or tits, its gonna cause a problem.

Thanks everyone for the advice. I'll try them out and hope for the best.
And Rhino70, the coolant never really drips down to the ground, it basically just burns off on the way down and the last of it happens to hit the down pipe where it just steams off, so hopefully no animals will be harmed in the making of this yj

If you get lucky it may just be the water pump gasket. If the block is rusted on the gasket face you maybe able to use JB weld or the Moroso block fix that was mentioned above. I do know that the guys who do the 4.0 haed swap fill the unused cooling ports in the head with JB Weld without any issues. Good luck and let us know how you make out!

Bardahl Stop Leak. One of the few stop leaks you can keep in your radiator fluid. Why not? You already have a cracked block. Just pour that liquid chunky goop in there, and let the magic begin.

I think that Bardahl stuf is for leaky Radiators only..
I'll replace the water pump and take a look and go from there..
