I am looking at rebuilding my 4.0 motor with 3K miles on it because it sucked in water when I quite suddenly found myself in a bad situation. A month before that I had to replace an AC actuator because another puddle swallowed my jeep whole. My questions are:
1. How do I waterproof the engine compartment? Should I just buy a snorkel?
2. How do I keep water/mud out of the AC tube that comes through the firewall? I ruined the actuator last time water got in there. Does it matter if I run the AC when water gets in that tube?
3. Since I have to have the engine taken apart anyways, is there a couple components that I can install that will give me a little HP/torque? Roller rockers, cam, things like that.
Well basically to waterproof everything you would want to add a snorkel like you mentioned and then silicone everything else you can see that could potentially let water leak into it. It's a pretty laborious procedure to go thru.
And if you are rebuilding it anyway then you can put a new cam in it and get some nice HP and Torque out of the whole deal. I think one of the mags just did an article on this if I remember rightly.

Sorry about being so blunt, just don't understand how getting a pair of pants wet, to check the depth of a crossing, is harder, than rebuilding a engine. There are so many other components to worry about as well. All your electical system, ECM, etc. Getting water and crud into your diffs. The damage is endless if you go past the center of your wheel. How hard is it to stick your head out the window and see how high the water is on your tires???????
Be easy on Blu! He's very passionate about water! (got the same when I joined!) Don't worry, he'll help ya with anything else! I had the same prob with my Ranger, and I am a little leary of "puddles". (got stuck in a HUGE rut and fried my tranny)
ETA, I'm not laughing at the original posters problems, I just get a kick out of the general hydrophobia.
techie_medic, why do you feel the need to rebuild your engine? you don't mention any damage, only that it inhaled a bit of water. I've done that a number of times and never had to rebuild.
