So I have a jeep rubicon about 40k miles on her with zero problems! ( Not a single one of the little weird problems so many of have come across.). Obtained it after my last jeep was totaled on the highway a few years back thanks to an aweome dealer that cut mr a huge deal after hearing the story.

Im In Houston as some of you know has been in themiddle of a crazy drought for some time now. About two weeks ago during one of the first real rai s in months my Rubi dies and I haveto have it towed. THEN I get the phone call telling me what was wrong with it. Water in the engine! Enough to completely kill it. Good news is that the insurance company is replacing it with a brand new engine along with a new soft top since mine was torn. ( traveler insurance has been very good to me ). But I find myself perplexed!

Just thought I would share... ( sorry for any typos using jk-forum.mobi from my cell)

 

Look for a long repair time. There are NO long blocks available. All they can do is order a short block and have your heads redone if they were not damaged. If that's the case, you better stay on top of them or they will try to cut corners on the heads to keep their warranty costs low.

 

There were intersections with high water but nine that were high enough to breach air levels. If they told me that with my last jeep I would have been like "yea. That makes since. ". But I have kept this one out of the water. I didn't have the tip on it sk the dash was soaked from rain but all the electrical was fine. Like I said I am perplexed.

 

As I've said before the stock intake opening is in a bad place. Water gets thrown across under the hood by the serpentine belt straight towards the airbox snorkle.

 

I'm betting you'll have better luck than "Redneck"had due to the fact that "Supplier's Park" is back up making "2010"models. If my memory is correct his engine problems were during the spring/summer Shutdown. Hope you get yours back soon.

 

I just thought I should mention that you can hydrolock an engine with the intake above the water line... Open exhaust valves will let water fill a cylinder if the water level is higher than the exhaust manifold via the exhaust system. The JK's exhaust valves are well below the induction air intake.

This is why some military vehicles have check valves in-line with the exhaust system. Should the engine die while fording, the check valve closes and water will not back up into the motor through the exhaust.

the exhaust is the only way I can think it is possible. And have seen it happen on the trail before (But usually when someone tries to restart with the pipe still underwater )

 

I was trying! But couldn't come up with the funds to cover the difference in cost and additional upgrades to make it able to hold a hemi.

 

Shoulda got some hemi stickers on the engine before they looked at it. Tell em it came with a hemi, I want one back in!

 

Thanks for the Hydro info. Now, I'm going to move the exhaust pipe higher.
