Broken piston / unloading a project Cherokee

Hey all,

I have a 99 Cherokee that starting making an ugly knocking noise the other night. Initial opinion from a respected shop is that it's not a lifter and not a rod bearing, leaving a broken piston as the next likely culprit. So two questions:

1. How likely is this to be the actual problem? The shop hasn't dropped the oil pan to look for piston pieces.

2. I'm not really keen on dropping $4K at a shop to put in a rebuilt engine, and don't have time/space to do it myself. What's the chance that somebody would take it off my hands, and what's a ~reasonable~ asking price for a barely-running but otherwise good condition Cherokee.

Basic specs on the rig :

The good : 99 Jeep Cherokee Sport, Black, 4.0 L, 4WD, 185K miles, manual transmission. Never wrecked, recently rebuilt clutch with less than 10K miles , newer heater core and AC compressor, brand new alternator and parking brake, matching tires (similar in style / application to the stock tires) with less than 5K miles. Non-smoker vehicle.

The bad : One piston likely broken, engine block might be rebuildable. Radiator has a small leak. Brakes servicable but will need to be redone sooner rather than later.

I'm in the Portland, OR area, if anybody in my neck of the woods is interested in it, drop me a line here and I'll figure out how to connect.

Sure it's not the flex plate? They tend to crack and make a "knock"

"****, I might **** around and bring the Jeep back No doors on it, flexin' with the seat back"

Thanks for the reply. I'm basically looking for anything other than a dead engine. Does a broken flex plate knock when it's not in gear? This engine does.
