hey guys, i am working on getting this breather extension kit installed. (i know many people may say it can be done cheaper by just going and buying the parts yourself, buuuuuut im lazy). My questions are rather general just hoping for someone to say the right thing that will make me understand.

First, in the kit there is a long thick hose (sorry i dont know the actual size). This is the hose that goes from the air box to the rear axle. Also, there is a thin hose thats like 2 feet long. Does anyone know what the thin hose is for?

Second, the instructions that comes with the kit are absolutely horrible. It basically says, cut hose from engine to air box. Attach large hose. run the hose without hitting move parts or hot parts. splice where you need to. yikes! If you are look at the front of the jeep, air box is on left. If you run the hose down from the splice, the breather on the front axle is on the right side. should i pull the breather hose and cross under the engine (strategically) or what?

Without sounding like a total noob, i am attaching the breathers from the front axle, transmission, transfer case, and rear axle. is it pretty obvious which tube is the breather. after crawling around under the jeep i have found the obvious candidate tubes, but i am nervous to start yanking/cutting hoses.

Anyone else that has installed this kit, or just extended your breathers yourself, have any other tips on this install.

Thanks for any and all help/advice.

Cheers

 

I had mine installed while they were doing other work, and the one ting they did was put clamps on everything, so there was less chance of them coming disconnected

 

clamps is a good idea! Anyone else have any recommendations ?

Thanks!!

 

just go buy some tube at napa along with clamps and save yourself alot of cash

 

Running any kind of oil breather hose to the airbox is a bad idea IMO. Overfill you diffs once and you'll see what I mean. You can buy tube cheap and run it high enough.

 

You can buy expandable end caps, that look like a little accordian, that will expand and contract. You don't really need to have the diffs/t-case/tranny breathe per se, just need to let the air expand and contract, as it heats up and cools down. SO, you can leave the hose where it is, and put these caps on the ends, to prevent water etc. from getting in, and still allow the air to expand. It's better, easier, and cheaper!

 

I just did a search for 'expandable end caps' but could not find anything like what you are describing. These sound like a great idea and I'd like to look into them. Do you have any idea who makes and / or sells them???

Thank You!

 

Bellows, that's the word I was looking for! It's a bellows that clips onto the hose, or directly onto the diff. Here's a link to a Canadian place that has 'em for Toyota axles, but I'm sure you can get the bellows anywhere, and just use a double finned connector to splice it onto the hose.

cool, now to hook a set of bagpipes up to it and we've got the wimpy horn problem solved too.

In all seriousness though, that's a really cool idea, thanks for posting it.

 

The directions are lacking a bit. I chose to not install mine to the airbox, and used a catch can instead. I'd rather have oil puking into a catch can, than my airbox, or down the sides of the frame.
