So i am going to extend my 4 breather lines tomorrow. However in a quick prelim inspection I see this breather right in my face on the valve cover? Any ideas. It goes behind the block to but then i loose track. I have posted it below. In the second pic you can see another breather on the firewall. Also the front axel breather is in the same place. Is this a breather for the block or possibly the transfer/trans? Thanks for your help!

 

It would appear that you have long breathers from the factory!

 

I'm going to assume the one on valve cover is your transfer case breather. You should be able to follow it all the way down...

 

I believe this is the only one that high. The one on the firewall sounds like either the inaccessible tranny or transfer. The front axel is in the same spot. No idea bout rear yet. I plan to run all into the engine bay all into one billet bracket. Keep it nice and clean.

 

Well i was able to follow it till it went behind the block. I do believe the one on the firewall is the tranny vent as it seems to be tied to the dipstick. So i assume this is the transfer case.
