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?

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.
