OOPS, I put this in the wrong forum. Can you put it where it belongs?
It's a 2002 Liberty Limited 4x4. I bought it 32 days ago. It has 134397 miles on it. Of those, I have put 667 miles on it. First thing I did when I got it was change the oil and filter. Nothing strange there. Changed the tires, it's all good. The independent car dealer put a new Cat on it, and then had the Chrysler dealer replace the ****** mod and switch under recall warranty, to fix the light issues with part time, full time 4x4 etc...
I started seeing coolant under it a few days after getting it back from the Jeep dealer. It never lost more than a pint or two before I refilled it. I changed the water pump, even though, when I got the original pump off, it was fine. It was the gasket that was leaking on the water pump. I installed a new thermostat and replaced the upper water hose at that time. All good.
I decided to replace the spark plugs, because who knows how old they were. After replacing the spark plugs I took it for a test drive. It was running great. I went about 1 mile and turned around. About half way home I started hearing a loud Tat, Tat, Tat, Tat sound that was consistent with the RPMs. No lights on the dash and the temp was barely up to operating temp. I made it the 1/2 mile or less home and shut it off. I coasted most of the way. I checked the oil. Right at safe level. I checked the coolant. Right at cold fill line.
The only thing I have done so far is remove the belt and see if the noise is still there. It is. That takes the alternator, power steering pump, and A/C compressor, out of the equation. Did I blow a head gasket? Suck a valve? throw a rod? Any help here would be great.
