Lost In The Woods: XJ/4.0L Dead Engine?

I would appreciate anyone's suggestions. My Jeep is currently abandoned in the middle of hunting season and I'm not sure what to do next. I don't want to lose it to target practice!

I was recently out driving and needed to ford a creek with a steep incline on the far side. After several near successes I decided to try a little more momentum. My engine fan bounced into my radiator and carved a large hole. I quickly backed up and parked the Jeep in the safe location so it wouldn't overheat.

I returned and installed a new radiator. Not quite understanding how the pressure bottle worked I put a few quarts of coolant in the top hose before attaching it to my engine block. I started the engine and saw the expected smoke from the coolant burning off (it had sprayed my engine compartment pretty thoroughly). Then I noticed more smoke pouring from the tailpipe. I turned off the engine popped the hood and saw the pressure bottle totally full. I opened it and it sprayed out under pressure so I unmounted it and dumped the whole thing out.

I let the engine cool and slowly added coolant to the bottle. I waited for it to seep down the lower tube before I added more. Then I started the Jeep. It'll run for 15-30 seconds, very rough. The idle varies wildly and more fuel doesn't help. It dies fast and more fuel just floods it (you can smell the gas). Sometimes it makes a very odd noise that almost sounds like a broken clutch - at least it seems to be coming from the back of the engine. Very fast and rattles a lot.

I'm guessing I put in too much coolant and it blew past the seals. Does anyone think draining all oil/coolant and replacing oil filter might help because coolant is in the oil or does it sound like the engine is totally fubar'd?

There isn't a lot of smoke coming out of the exhaust and the temp gauge shows a normal temperature increase - suggesting the cooling system is working now.

Currently access is limited because of the weather and a forest service gate. I don't have access to a 4x4 since everyone I know is Elk hunting in the other half of the state. I can get about a mile away but I have to go the rest of the way on foot, over the creek I broke the radiator on. I need to get the Jeep out but I have to take the long way around (30+ miles).

Little more info on how the engine was running immediately after the water crossing and immediately after you swapped the radiator may help a diagnosis. Honestly, it sounds to me like you either hydrolocked your engine or overheated it and blew a head gasket. Fubar engine, either way. Just overfilling your closed cooling system isn't going to force coolant into the engine. At most, it's just going to make that cheesey plastic expansion tank crack. You probably sank the intake during the water crossing, allowing the engine to ingest water. Since you can't compress a liquid with a conventional auto engine, your piston/ring lands/rod/etc give, rather than the water.

Change the oil, filter, pull the plugs and check their condition, pop off the distributor cap and spray the distributor inside and underside the cap with WD-40. There's also a possibility you damaged one of the EFI sensors with the water, but the coolant in the oil is a bad sign.  

Thanks.

The engine was running alright beforehand but it seemed to be overheating a little. I stopped for an hour or so with the hood open. There was a little inconsistency at idle on the way down but I was engine braking most of the time.

The creek was only a foot deep at most but maybe I hit it too hard and sucked up some water. I hit a hole on the opposite side fairly hard and the smoke from under my hood started immediately. I had assumed it was coolant hitting the engine and burning off. I'll definitely try the hydrolock fix. Is there a good place to stop the EFI from working so when I pull the plugs and turn it over it won't spray fuel?

I'll also try to plan for a head gasket replacement as well.

If all that doesn't work I'll find a way to drag it out. I really appreciate the help, I really wasn't sure if too much engine coolant could do it, thanks.  

I am not understanding some of the questions and answers but it sounds to be running only badly? I have had a lot of proublems with water getting into the TPS and causing bad idle and running conditions (87-98 4.0 motors). I have replaced many of them. some have caused the engine to die and or not start after just getting steam from a water crossing!Early models need adj or installed at same postition it was removed.purched at a jeep dealer it will have new screw's so you can have the correct torq's type screw driver and a bit on a 1/4" ratchet and short extendison.Also might get a distrubtor cap and rotor!it may have arc'ed inside(not repairable!).
