Water running out of muffler

I am looking at a 1999 Wrangle-6 cl. std trans, A/c
Unfortunately when it is running it has a steady drip of water comming out of the rear of the muffler-and it has been doing so for a while.
Oil has been changed-no water in the oil.
My first thought is-head gasket. However-unfortunately I can think of cracked block or head.
Do these engines tend to crack the head or the block?
Am I being an optomist in thinking head gasket?
This engine has 150K-am I kidding myself with the idea of replacing head gasket,
valve job?
Appreciate the comments.

Water coming out of exhaust is normal. Unless the radiator is emptying you have nothing to worry about. Now if the water in the reservoir and radiator are disappearing that's a different story. But we do body work for dealerships and the new cars we work on with 20 to 40 miles on them have water coming out the tail pipe.and my jeep motor has a recently rebuilt motor that drips water out the tail pipe.

Ditto on the water. Now if it had antifreeze in that water, you would have a serious problem.

Water is an emission of the combustion process and perfectly normal to be coming out of the exhaust. unless as others said if it is antifreeze you have a problem. It may not hurt to drill a small drain hole in the back on the bottom of the muffler to help drain it and prevent it from rotting out on the inside

Most mufflers have a "weep" hole at the back so condensation can escape. It also comes out of the tailpipe, which is an indication of a tight exhaust system. That's good. I've never seen coolant coming out of a tailpipe, it would be white smoke. If you're not loosing coolant and there's no coolant in the oil you're fine. If you happen to be loosing some coolant check for actual leaks and/or have the system pressure tested. You're getting ahead of yourself. There will be enough things to fix. I wouldn't be concerned with something that's not there.

Just like every other car truck or Jeep out there they will puff a little at startup until they are warm So its normal and you will get black sooty water out the tail pipe at first start every morning so don't be alarmed.

Its great that you were paying attention to what was happening and asked the question because it wouldn't be the first Jeep for sale with a major problem.

So continue to check it out and make sure.

It has to be determined where the leak is. Get the system pressure tested. It could be bad or as simple as a hose leak when it's under pressure.

One other way to check if it may be the head or head gasket. With the rad cap off get the jeep to temp and watch for bubbling, also if your mechanic has a sniffer emission machine they can hold the probe over the open rad cap. If you have a leak the machine will pickup hydrocarbons coming out of ther radiator .

If your radiator cap is off and the jeep is up to temp you should see movement in the coolant. If not, your thermostat is not opening.

Look, water comes out of the muffler in all gasoline engines. Take the jeep to a mechanic if you're nervous about it. Pay the $$$ to get it checked.
