Transfer case breather vent hose mod.
I was thinking that some of the oil leakage from the transfer case was due to the oil sticking the breather closed. Last year I popped off the breather cover and spring and slipped a hose over the remains of the breather and then ran the hose up to the top of the firewall. I was always concerned about the hose remaining fixed in place and last year when talking with Georg (orangefj45) he said he uses a barbed elbow threaded into the top cover in place of the breather. I got an elbow from him and now that it has warmed up I decided to install it.
I was pleasantly surprised to find that the hose had not come off the breather remains over the course of the past year but I proceeded anyways.
The breather threads into the cover and is a 27mm bolt. Remove that. Next with a 1/2" NPT tap rethread the top cover (if doing as I did and threading in place put grease on the tap to catch the cuttings, though I doubt the soft aluminum will do much harm to anything). You'll need to thread quite a ways as the 1/2" NPT is slightly larger than the original threaded hole. I ran the tap in probably 1/2" at least, remember that the NPT is a tapered thread so to allow it to tighten down you can't go too far. You want the elbow pointing up as I did so any oil that does find it's way to the hose can drain back to the transfer case. Blockages in the hose, like oil pooling, will defeat the breather function. If you have a transfer case saver as I do you'll need to install the one piece barbed elbow first and then the transfer case saver or use a two piece part as the transfer case saver rib interferes with the barbed elbow when threading it in.
You can see the tap needed, the barbed single piece elbow and the OEM breather in the picture.
Charles,
This is really timely for me as I just finished a mod which combined my breather hoses from the axles as well as the e lockers. Now they all lead up the firewall to a small airfilter. It would be nothing to plumb in a t fitting and pick up the breather from the t case. What do you think?

Today is headliner and windshield day! I'll be posting pics as things progress.
Good stuff!
It has been a while since we have had any headliner install pics.
