Ok, im going to be the first to say it. Im a dumb ***! Ok, i went mudding the other day, and went in some water, STOCK. and took in water, killed the motor right away. freezing temps, i thought ice inside and just needed to thaw after hydrolocking. wall, motor moves to a point, then the other way to a point. so i concluded bent rod. Can i just replace it? or do i need to do a rebuild? limited funds so cheep is what i need. please and thank you

If it is a bent rod at a minimum the oil pan and one of the cylinder heads has to come off. If it is just the rod you might be able to get by swapping a used rod/piston and just doing the bearings and rings on that one cylinder.

This is what I did when I managed to bend one on a 95 Trooper though it was not nearly as bent as one would have to be to keep the motor from turning over. Truck was still running fine 40k or so later.

If I had it to do over again and had access to a hoist and stand it would be a tradeoff as to if I would do it with the motor in the truck or if I would pull the motor and work it on a stand. Is a lot of hassle involved in pulling the pan with the motor in the truck and also a decent potential for breaking off a head bolt. With the motor out of the truck the pan is super easy and also with the motor out you can use an impact on the head bolts which greatly reduces the likelihood of breaking them.

I don't know about Florida. But around here you can buy a good running Rodeo for $1500-2000. You could get $300-500 scrap fee for your truck. It might be less expensive and less work to just replace the truck. Otherwise, maybe just swap in a good used engine if you have capability of working on the rig yourself.

At first blush I agree whole heartedly, then I asked myself... What cert did you get? Internals covered or no? Suspension tech, tranny tech, electronics specialist? These areas wouldn't cover engine internals (though the Trans tech would have training on mic'ing internal tight tolerances).

So my response is this:
Pull the pan & see if its really a bent rod(s). See if you bent/broke the crank (it might be). If you housed the crank you're not getting off cheap, if its a single rod swap that one out & hope. But understand you are hoping the crank isn't bent just a few thou, & hoping the cyl wall isn't chowed. A running pull from the classifieds or junk yard might be your only salvation, depending on damage.

Ok, i know what i SHOULD do, but i wanted go see what others have done, and gotten away with. I have no vehicle at the moment, and dont have the time to do all the proper stuff. and for the record, i hold all certs from ford, but the trans, and diesels.

Fair enough. As stated above people have gotten away with a 1 cyl bandage. So best case you're looking at pulling ; motor, intake, head, oil Pan, main bearings, rod bearings, offending rod/piston & all galleys on the way back up. I do hope that gets you back on the road man.

Did the water crossing go over your hood, or just enough to choke the intake?

Well, looks like i found a 97 engine with low miles for 550, but need to wait till i get the money. But, when i was looking in the manual, it tells me to remove the trans. Do i really need to? I mean, ive had it out 7 times already, and can have it on the ground in 45 min, but i dont want to if i dont have to. please and thank you!

That's a decent deal on a running pull, is it same motor? I forget where the divorce of v6 motor happens, is it 95->96 or 96->97 that the 3.2L got redesigned?

well, over a year later, im back. junked the old one 96 and got another 97. working on making the proper mods and taking it back out to the bush. i junked the old for almost 600 and bought the new one for 600. not bad right? 20,000 less miles, unmelestod, and old person owned! needed a coil and oil change, and running great, but i think the transfer case is about shot. is that removable from the trans? i forget! lol

The auto Trans is designed with a removable t-case. The manual is technically removable, but you have to get a bit more involved. The front of the t-case on an mua5 is part of the Trans, so you have to open up the Trans to get the front plate off. Or you can just swap over guts & new rear plate.

So i better off just doing a trans swap? Again? Did one on my old one due to the input shaft busting

It depends on what's going out.

If the output from Trans into t-case is good : swap guts & rear shell.

If the output from Trans into t-case is shot : full swap will be faster, but could crack open the Trans & do just the t-case if you're so inclined.

Ill be honest. I have no idea whats wrong with it. I have to get it on a lift to figure it out. When i put it in 4 high it makes a ratchet noise, and the same in 4 low, but in 4 high the light will go out untill i push the shifter back up again. I think its in the transfer case since its only in a 4 wheel mode, but i was also thinking the cv axle or something. I bought it as is and am fixing things as i go.
