Transfer breather pipe

Hi all, can anyone tell me where the transfer box breather pipe is located?
on a mission lately to try & rectify as many oil leaks as possible (my block paving is looking decidedly patchy) having spent two weekends replacing the rear diff oil seal/flange joint only to discover the breather was blocked Ive decided go for the simple fix first. p.s does anyone one know of some good drive way cleaner Snoops

I think its tight up on the near side of the box and a bugger to get at from below, unless that was the auto box, in which case its on top of the box and not as bad as the other one. It was a few weeks ago i did it

Thanks Hifly, it is on an auto box & i have just found it. Again thanks
