snorkel might be a stupid question

[jcbannis]

this might be a stupid question but im new to this part but with a snorkel kit if you were to get your jeep in high water wouldnt you get water in your oil?

It's a great question. The snorkel only solves one problem, albeit a big problem. Keeping the water out of the combustion chamber. It's just one step in many required to make a vehicle ready for a high water crossing.

Wayne (cantab27), down in New Zealand, takes his rig in the water all the time, along with several other people in the area that he lives. He's an excellent source of information.

if you plan on going in deep water you will want to extend your breathers up to the highest point under the hood

Don't some people run those hoses to the snorkel?

that to me would not make sense , cause then you need to drill into the snorkel

[96xj]

also with deep water you want to put water proof grease in all your connections and keep up with changing it and relocate your ecm

[jcbannis]

thanks guys it just didnt make much sense to me

[96xj]

if you do deep water trails you want a snorkel , what a snorkel dose is relocate your intake so it will be higher then you 5 feet check this out

That was actually a good question. A snorkel can serve two purposes. In the Aussie outback they allow a more dust free intake by raising it up above the wheels. If water is your game, then you have to connect all your breathers to the snorkel. That includes differentials, tranny, tcase and engine and maybe power steering.

steves onto it , two uses for snorkel ,,, dust in the out back ..water crossings .... think ya find breathers on diffs on xj are factory ,, haven't had to do anything to mine ..as told to me from 4wd shop , who put lift in ......i know they fit breathers in the tj trans down here ..they don't like water .... can run air inside diffs to pressurise to keep water out ... just looking into this now ,, I'm funny about oil leaks in my jeep , as oil gets out water can get in ...people wire fan so they can stop it spinning in deep water ,,, or as we do tie a sack or tapeline in front of grill when crossing deep water ,,,the old condom trick on the dizzy .. there are heaps of little tricks ,,

When we work on the Mighty Mites, (Project HUM WEE) we see how much the military put into water proofing. The gas tank breather, differentials, and the gear boxes are all hooked into the air intake, which hooks up to an optional snorkel and rated for 4.5' of water.

theirs are couple of other things to look out for when playing in rivers ..traffic :rotfl2:

try and keep the wake of the water in front of the 4x4

if in doubt get out and see how deep the water is ,, easy here as water is fresh river

fast running water enter river on a angle to flow with the river , will try and get pics of that this Sunday on a run

and if in real doubt let someone else go first ,cause a hydrolocked engine is a dead engine

also on every river run i grease all grease nipples (can i say nipples tony lol) before and after , you would be surprised on how much water comes out .....

[Mudderoy]

Being hit by a boat would be an interesting claim with the insurance agent.

[4.3LXJ]

One more tip for fellas like Warren who have front spindles and hubs. Pack the space in the hub completely with grease and it won't suck water into the bearings. The same with rear bearings if you have that type.

your right that doesent make sence to me ether because what about all you electrical componets under the hood!?

[modestmar00xj]

it seems kind of complex just to drive through water, plus i dont want to pay the ultimate price with the engine hydrolocked! ill stick to the trails and mud!

[4.3LXJ]

Those have to be waterproofed as well

[modestmar00xj]

ahh i see! thats crazy, but makes sence!

[4.3LXJ]

If you are truly going under water, everything has to be waterproofed. All vents, even the breather for the master cylinders need to be ducted and sealed into the snorkel. However, after having said all that, the XJs have an air intake to the air box in the grill. When you hit the water it is easy to push water up and into the air box and then hydrolock an engine. Most people that get snorkels are just gettiing one to off set this and not to truly go under water.

[cantab27]

see how deep i can get it on sunday for ya .......RIVER RUN ....

Ahh ok now this is the details i needed to know, now it makes sence! thanks.

[LizardRunner]

this may be dumb but what about water sealing off the exaust and causing the engine to die? If I was going to go scuba diving in my jeep I think I would get all breathers to a snorkel and then extend the exaust pipe up to the same level as the snorkel.

[4.3LXJ]

That is a good point, particularly with an engine with an O2 sensor. The trick is that you have to keep the engine running or it will allow water to enter the exhaust system and just a little steam will foul an O2 sensor. Military rigs, such as my Mighty Mite (see Project HUM WEE) not only have a snorkel for the intake, but the exhaust also.

they sound funny under water ,,like the jeeps passing gas
