Friends Engine Drank some Water. I want to help him.

I usually am on the CJ forum but since he has a wj I am here with you strangers. haha. Hes not an internet guy so I tell him I know just the people to talk to. Ok so heres the deal. He was on the beach, water came in, hit his vehicle.

It never actually cut off when water came in, just started running like crap, (as soon as the water hit). He got it away from the water. Pulled the air filter and tried to crank it again, wouldnt work then. Was soon wise enough to call a tow truck. Tow guy sprayed some 'water displacement 40th attempt' on around the plugs. Managed to get it to crank, ran it for 20 minutes saying that would dry the engine out. Buddy then got the jeep towed home, says he can crank it as it sits but the engine feels very week and it wont shift into any gears. says if feels like a cylinder isnt hitting (he doesn't know much about engines) and that he can hear was sounds like a chattering ticking noise coming from under the vehicle.

I have instructed him to pull the plugs and try a few cranks to remove any water, as well as replace the air filter, oil, and oil filter. along with checking out the diff oils and trancase and tranny oils.

I have a Cj, I read what I could on this problem, I don't think its a fully blown hydrolock, He gets no smoke anywhere.

What do you guys suggest? I told him it was atleast good his engine ran, but to stop trying to run it for now, until he pulls those plugs. I think that tow guy was an idiot.

You guys think his engine is shot or is there some hope still left in this cruel world? Please help me help him out, he doesnt have money for a new engine nor a mechanic right now however he is very mechanical inclined.

Thanks,

Here are some things I would do:

1 - Pull Spark Plugs, turn engine over to see if water is in the cylinders. Do a compression test to see if any valves or rods are bent. Change Spark Plugs (already have them out)
2 - Oil may have water it in, change it
3 - Transmission may have water in it (causing shifting issues), change it. If you find water when you change it, warm to operating temp and flush it again.

Remember that oils weigh less than water, they float. Checking the dipstick will not necessarily tell you if you have water in your fluids. If you have a TON of water, the oil may actually look like chocolate milk though.

BTW- what engine does he have?

First drop out of a pan should be oil. Water is heavier as mentioned. If it has water in it then should be easy to tell.

Cant believe i forgot the engine the first post. I believe it is a 3.7 liter v6. I have told him to do all this. Also, as far as the differentials, isnt it wise to look into those as well? pretty much anywhere there is fluid?

Any 1 more question, what engines would drop into his vehicle if he did infact have to replace it? currently its a 05' with a 2.7 v6 and AWD transmission according to him, not sure if thats the quadratrac or what.

None of those engines come in a WJ ! Check your info! Must be a WK if it's 05. Wrong forum.

+1 on compression check, easiest way to find out how much real damage was done. Also the 3.7s I've worked on (2002ish Jeep Libertys), have a tendency to explode all on their own without the help of hydrolocking. Good luck either way, I hope it's something simple.

Likewise, thanks for the support. I may have to drive up to VA this weekend one day so he will get a handle on it. He is one of those guys that never stops working and doesn't have time for shenanigans. although i wouldn't consider this a shenanigan.
