Wj Problem

ok i have a 04 wj limited with the 4.7 in it. In the last few weeks its been sounding like water under the dash, i have been busy with work so have not checked into it, my wife called me the other day, said check engine light came on, and said #8 cylinder missfire. Well, i just got home, checked coolant, its a lil low, gonna top it off, but i had topped it off about 2 months ago on our road trip. Oil looks fine, no antifreeze in it. I am gonna take to dealer monday as we have 800 miles left on warrenty. It will prob be void since i did a lift on the jeep with bigger tires though. Anyone got any ideas or common problems? I know these are known for head gaskets, anything else?

Heater core, check if pass side floor carpet Are wet, might just be air in your system as well.

Hmmm... I'm getting something similar though isntead of water, its more like air sound... like a slow air brake on a tractor trailer

Interesting to read about heater core. I noticed in the summer time I'd get a wet spot on the passenger floor mat... but that only happened with the A/C going, a passenger actually complained of water dripping down on their feet. Not running the A/C resulted in no water seeping. Any ideas?

That would be a clogged ac drain

the dealer has the jeep right now, trying to say its a spark plug bad(270$ to fix) and air in the coolant.. total bs i already bled the system last night, its burning coolant somewhere, i have 800 miles left on the engine warranty. I am making them do pressure test to see if the head gasket is leaking. This dealer is a total joke, but while under warranty they will continue to work on it..

That sucks big time! Fwiw in a wj, a leaking heater core won't always produce a wet carpet. It's rubber lined on the bottom so if the coolant is leaking behind the carpet you won't know unless you pull the carpet back.

I don't see how tires and a lift would cause a head gasket to break. Completely different system.
