I am in the process of totally waterproofing my trooper for river crossings. I have read a bit about raising the diff & tranny breathers up someplace high on your vehicle. I was thinking it would be nicer to drill and tap into my intake bonnet (carb hat) and user that already filtered air as a breather source for the diffs etc. I was also thinking of doing this with the valve cover breather instead of using separate little filters I can just use my main intake filter. comments suggestions?? Thanks

I have seen clear fuel filters plumbed in the vent line. The filters trap water yet allow air to breath. If you see water in the filters, time to drain the the diff. I have not done this, but the theory seems sound.

Up high in the engine compartment with the little clear lawnmower fuel filter on it is tried and true. IMHO, drilling and plumbing into the intake is just creating a source for potential leaks that could cause headaches down the road.

Well I definitely want it higher then the engine compartment. If i were to not use the intake I would go up to the top of the snorkel with a little filter. But I think keeping the hoses under the hood would more professional and neet. I actually just my new inline air filter from PRM.

and the plastic that surrounds the filter itself is quite thick and I think would be a great piece to plumb into. I believe if a barb is tapped in and then glued and then the hose put on and clamped it would be pretty solid. I'll get some pictures up when I take some.

Keep the ideas coming. Thanks

DONT FORGET THE BREATHERS ON TOP OF THE TRANS AND THE TRANS FER CASE IF YOU ARE GOING IN THAT DEEP JERRY

Here are some pictures of my new intake:

Personally, I would be hesitant to plumb into the intake. First, the intake at that point is a negative pressure area. It may not be as much as intake vacuum, but it is still negative. Breathers need to breathe. This includes normal expansion and contraction of the air space within each of the cases or axles. Secondly, that is the air for your engine. You don't want to comprimise it. If you do take on water somewhere, then you run the risk of pushing water, oil, junk, ect into the intake. The risk does not outweigh the benifit of having them plumbed to the intake.

Two option for you include using an expandable accordian vent. These are closed baloons which go directly onto the vent, or you could plumb them remotely. The other is to plumb the lines into the passenger compartment.

As mentioned above, a small filter allows you to detect moisture (there is no "filtering" of air going into the breather) and if you add a loop of hose beyond it, with the end pointing down, you cannot get water into the breather, unless you submerge, then roll. At that point you have bigger problems.

Good luck. Don't try and overdesign this little project.

Thats what I did on my rear axle. I used a Suzuki part # 27491-38F00 Final Bevel Gear (Rear) Breather, Case for an ATV.



I've had it on there for about a year now and so far no problems.

PS. Most of the red/brown you see isnt rust, its Moab dirt <img src="/forums/images/graemlins/smile.gif" alt="" />

Very cool, you have sold! Now where do I pick them up? Also would they work fine for the tranny and transfer case?

THANKS!

Got mine from the local suzuki m'cycle/atv dealer. Had to order it since they didnt have one in stock. Should be fine for trans and t'case breathers too.

Right after I posted this I went to get something to eat and crawled under there to turn my shocks down and saw that my passenger side axle seal is leaking now <img src="/forums/images/graemlins/ignore.gif" alt="" /> What I get for bragging on it LOL. I doubt the breather is the cause though or it would have done it on several long drives to the mountains for wheeling last summer or the 300 mile drive to moab. Most likely is due to the 88k miles of neglect from previous owners (at 106k miles now).
