I went through some deep mud about 3 foot deep and some other muddy water about 2 foot. Two weeks later engine began making a knocking sound when I started it. I took it to the stealership they said there was water in the bottom end of the engine and dont know if they will cover it. They said something about replacing bearings? Im heading down tommorrow to check it for myself

I didnt stall the engine while the muffler was under water.

Water didnt enter through the intake either Just a few specs of mud on the filter and a little damp .

I hit the mud pit and bogged down a little like the engine lost power but it never turned off, I mashed the throttle and pulled through it.

Could water have been sucked up through my muffler?

 

edit: hitmoney you beat me to it... repeat of what you just said

There is no way water went up through the muffler because the muffler doesnt suck. it has to come through your intake.

 

Yea I do have a CAI, I Thought I was going slow enough that the majority of the mud and water would stay well below the intake. I Belive some might have splashed up and in.

What bearing are they talking about?

Any one have to deal with warranty issues of this sort before?

I told 'em its a freakin jeep that what its for maybe I'll invest in a pre filter for the CAI to help avoid this next time.

 

The underside of the hood after.

You can clearly see the clean space where the CAI is.



The dealership kept saying it prolly came through the muffler which is really hard for me to believe. The air filter was a little moist and had small specs of mud on it, I didnt realize this little bit of dirt and moisture would so easily come through into the engine.

 

theres no fucking way that mud pit would have cause the problem...

its not like you were in the deep side. You did'nt stall the jeep or anything, so I doubt water could have traveled through the muffler and cats to the engine..


btw,,, I did say don't drive through that mud

 

maybe...
I have a nice engine knock.

the dealer says its normal...

I've never gone in a mud or water pit either.

 

Ok when was the cai filter a little moist right after you went thru the mud and water holes or later when you checked it?

I have to ask why are you guys running cai intakes and running thru anything deeper then a puddle on the street from rain? Sorry but you are just asking for trouble. The way that mud is up and over the hood and flares I would say you definately got enough thru that filter.

When you bogged down the fan could have shot water up right past your filter, I've seen it come out between the fender and hood right where the stock intake is.

Good Luck getting it covered!!

See Campcrocker he might be able to hook u up with engine if you need one

 

Water going into the intake would not cause water in the crankcase. Getting water in the intake will just steam clean your vavles and pistons, unless too much water is sucked in and then the motor will sieze, or hydrolock. You got water in your crankcase somehow, and that is what ate your bearings up.

 

If it is enough water that you sucked in then you could get some water to bypass the piston rings, and end up in the oil. It doesnt take much water in the oil to foam it up.
I recomend a water resistant prefilter on your CAI, and to change that oil after you go through deep water. I go as far to change the oils in your diff's as well if they were submerged.

 

Ok, not going to get in a typing match, so I'll just say this and be done. I am a former shop forman at a car dealership. I have worked at several dealerships. I have an associates degree in auto technology. I have been to countless GM schools and seminars. I may know a little something about what I am talking about. That being said, one way to clean carbon deposits out of your heads, pistons, and valve stems is to purge your motor. You purge your motor by running it at 2500 rpms and pouring water into the intake at normal operating temperture. This will steam clean your pistons, valve stems, and heads, removing any carbon deposits. If there was enough water sucked into the intake to get past the rings, the motor would have hydrolocked. Agree or disagree, that's the way it is.
