heavy85 Posted March 16, 2009 Share Posted March 16, 2009 I've consistently had problems with oil coming out the diff breather. Just switched to a finned cover an noticed it has a different breather. The old one was black plastic with an arrow on it. It's just a cap snapped over a tube - no filter, mesh, or anything. The new one is metal and the cap is crimped on at the bottom. Real question is if these diffs all slobber oil out the breather and I should go ahead and run it to a catch can or does it just take the other style breather?

johnc Posted March 16, 2009 Share Posted March 16, 2009 Yes, the R200 and R180 both tend to puke oil out the breather. Even the R200 in my 350Z does it. Remove the plastic breather cap, thread the hole for the appropriate NPT thread, put a brass barbed fitting, and run a hose to a catch can. Some people just run a long loop of hose instead of a catch can. Quote Link to comment Share on other sites More sharing options...
260DET Posted March 16, 2009 Share Posted March 16, 2009 Never had those problems myself although on the current Z I looped a breather tube like John suggests. I believe some oils foam more than others, that may be worth checking out. Quote Link to comment Share on other sites More sharing options...
