Front differential breather.... is it LEAKING or normal????

Noticed today that a very small amount of gear oil has been leaking out of the breathers located under the hood. Both caps spin and appear to work. Changed front diff and T case fluid 10K ago.

I use 4x4 on a weekly basis, and drove almost 150 miles in 4x4 the other day when the roads were awful. And it has been super cold lately (-20 with 0 degree highs)

Is this normal for a small amount of oil to be around this area?? (no drips, just oil spots on the surrounding metal and the breather tube?

 

a little bit of blow out is normal

 

Thats what I figured. And after using the SEARCH option, pretty much found my answer. Thanks for the input, love the info on this site!

 

Front differential and ADD breathers:

 

any need to extend these are they pretty good length for the most part? I know rear needs to be done and will soon be completing that.

 

Your airbox will be taking on water if these are.

 

thank you
