Do any of you have problems with diff oil coming out of the breather hose? Ever since I installed mine oil comes out the breather when...

a. Im cruising at high speed on the expressway
b. autocrossing
c. drive on very bumpy roads

I have NOT overfilled the diff. I do have a tomei diff and 4.636fd installed. Only thing I can think of is that the screw on baffle in the cover is serving to channel oil towards the breather hole. Anyone?

Come on... I can't be the only one on this board that has one of these things.

You need to do the catch can mod.

I've never heard of a catch can for a differential.

you replace the vent with a tube going to a can. I would post pics but it's in my HyperRev.
