Some people extend the trans and T/C breathers to the top of the firewall where the front axle breather is and the rear axle breather to where the fuel filler is.

Personally, if I had a snorkel (which I do, but it's not installed yet) I would run all of them to the top of the snorkel.

 

I didn't know they were there! Lol and do you just attach a rubber hose and run it up to those places or is there a special thing you need to do?

 

Many people just use a hose barb and some gear clamps to add to the existing breather hose. I don't like to take chances and it's not much more effort to replace the entire hose. You just have to locate where the hose comes out of each component and then route it safely to wherever you wish.

Front axle breather comes off of the top passenger side of the back of the diff, runs along the UCA and then up the firewall. You should be able to see the end with the check valve at the top of the firewall between the brake booster and the valve cover.

Trans and T/C hoses come off the top of each and then I believe they end near the bottom of the firewall on the PASSENGER side of the engine. But I'm not 100% on that. I haven't hunted them down on mine yet.

The rear axle breather comed out of the rear brake distribution block on top of the rear axle to the driver's side of the diff. That hose runs just into the frame. if you want to snorkel that one it's going to require the longest piece of hose (obviously) and probably a fair bit of time to safely route and secure it.

I would try to locate all of the hoses first and then cut off a sample of each before heading to the autoparts store or hose and fittings wholesaler to match the size and type of hose. That type of hose is usually relatively cheap so get extra. Remember, you will have to account for axle articulation with the diff breathers so you'll need some slack. Make sure you get new clamps to go with them, get check valves for the snorkel end, and stock up on zap straps.

Then set aside an afternoon (or a whole day if you're like me and like to inspect as you work) and have at it.

 

When I get some money coming in I will for sure do that!

 

Look at the link i posted earlier in this.

 

I have a cowl intake on mine as I didn't want the ARB style hanging on the side of my XJ to be torn off by limbs and trees on a narrow trail. That with the fact if water goes above the hood I'm SOL anyway as I don't have a sub. The vents are all moved to the top of the firewall in the front and rear differential comes out in the fuel fill door area also.


Be aware that you will still get water in the differentials if your in water very much as it will seep in from axle seals and such. For that reason I have drain plugs on my covers so I drain the fluids often and only pull the covers once a year or so to check everything else gears/lockers.


Good link if you didn't read.

 

Read that link. Very informative. Thank you

 

Any thoughts on running Distributor, Transmission, Transfercase, and Axle vent tubes all to some sort of air manifold (like below pictures) and that running the 5 into one medium tube up higher (like up a snorkle) topped with a simple pvc filter?

What about cross contamination of fluid gases? I know its just to handle the cooling and heating expansion of the fluid and the need for more or less air space and release condensation like in the distibutor (I believe), but do you think the 90 weight would put off gases that would contaminate the trans fluid, etc? (my main concern)
