Unhappy Stuck engine...2.4l , 4x4

Hello everyone...
Newbie to forum here...
I got a 2015 patriot , high altitude , with 2.4l and 4x4...
Water got into intake system and evaporated into engine...(valves open...
I pulled plugs and soaked with marvels and anti sieze (good one..)
Then I removed intake and seen water on top of valves that where closed..
I pulled oil pan and it had an inch of water in it...Engine was never started with water in it...
I currently have all cylinders filled with marvels...
and the engine as well..Been soaking for few days...Still wont budge...
Any advise??


Thanks

How long did it sit after the water got in? It takes some time for rust to develop enough to freeze the engine. Even then, Marvel Mystery Oil should free the rings/pistons eventually. I have been witness to mmo loosening up an old 6 cylinder that had been sitting for over 20 years.

Are you sure there isn't a problem with the rods/crankshaft?

Unless this sat a very long time is shouldn't be frozen up by rust and if it was the mmo should free it within at least a week or two if not sooner.

It looks like is sat for a month or soo with water trapped in intake system...
I drained transmission and found no water...I don't like design of intake...
for a 4 wheel drive..the intake feed shouldn't be so low to ground,,but whatcha gonna do...
I thought of pulling motor..but would be hard seeing I cant separate torque conv..
maybe , thinking about dropping subframe with tranny and all..idk...
I will let it sit for a week or longer...This motor only has 25k on it..

I'm with griff -- Marvel Mystery Oil is remarkable. I had a '29 Hupmibile that hadn't run since the late '50s. It was a hand crank and I couldn't budge it. On the advice of a friend I removed the plugs and poured in a lot of MMO and let it sit all winter. In the spring, voila! it would turn! Wahoo!

Then again you probably don't want to wait that long. I find it hard to believe rust could form that quickly and if it did, even if you get it started you may find an increase in oil consumption.

How'd water get in there anyway? If it was hydrolocked you're probably in deep doo-doo. You can google hydrolock and see what you find.

An inch of water in the oil pan? That's more than just evaporation or condensation could ever do. Do you have a blown head gasket or something? Though that would be green coolant and easy to tell from water.

A car moving through deep water can create a bow wave much higher than the actual level of the water, and it increases with speed so it's not improbable to see water going into the intake that's located above the rad.

A loose or poorly sealing oil dipstick can allow water into the oil pan after it stalled out, that's really the only area I can think of.

Your insurance should take care of that for you, usually flood damaged vehicles are just written off. If it was in fairly deep water (deep enough to get into the engine) more than likely the electricals took a good dousing as well.

He may have bought it to repair after flood damage. It can be done (as long as it isn't sea water)...and the electricals can be ok as long as they dry out before any current runs through them.
I did it with a Jeep Liberty a few years ago.

I worked for IBM and we used to take in the desktop computers after in lease expiration and literally spray them with an indoor pressure washer like a car wash by the pallet load. Then they stayed in the paint drying oven for 24 hours and worked just fine afterward. We tested them IBM then sold them as used computer equipment, much like a car dealership sells a lease car.

Ah, I never thought of that!
Weird that it would be stuck that bad, hopefully he can get it unstuck and the bores aren't too bad. I've unstuck a few old tractors and other farm equipment, takes a lot of patience. (just seized from sitting though, not water damaged)

It really shouldn't be hurt too bad after only about a month as long as it wasn't run with the water in it. Was it in a flood (not running) or did someone get it submerged going through deep water?
Keep on with the mmo....how are you trying to turn the engine?
I'd check the transmission too, even though it's supposed to be sealed...it's not exactly waterproof.

If you can even jiggle the engine just a tiny amount....the mmo can seep into the cracks and work even better.
I'd give it some time, but each day or 2 to try to move it.

There is a trick to wire a couple batteries in series to the starter to jolt it....but you risk burning out the starter and stripping the teeth, and possibly damaging the teeth on the flywheel too.
If it frees it, it's worth a starter though.

Mind if I ask what you paid? Did you get it at the auction, like CoPart?
