This is a part that's not for everyone but those of us who really push these cars at high speeds might have noticed the tendency of the transfer case to push oil out through the breather. This creates a mess under the car and risks starving the transfer case of oil which can result in nasty surprises.
After living with this problem for a few years I had a metal breather made that I connected to a small vented motorcykle brake reservoir in the engine bay so that any access got pushed up into the reservoir and so that I could easily add fluid if needed.
This is what the first breather version looked like.

This setup worked great apart from the o-ring not fully sealing in some conditions due to the built in groove in the breather hole of the transfer case the being too large for the it to seal.
The breather itself was turned, milled and pressed which meant it was pretty time consuming to produce.
So this winter while working on my car I developed a new billet aluminum version of this breather that's made in one piece and press fits into the transfer case breather hole instead.
Here is what the new version looks like:

I haven't started producing these yet apart from for my own use but if there is enough interest I could make a few more of them. So write a post in this thread if your interested in one.
