This is crazy. Something is causing this. It just HAS to be the vent.Speak of the devil, just drove about 700kms this weekend and noticed little oil spots all over the back of the car. I looked under Neath and seen a soaking wet rear diff and actually watched it drip. Greeaaat...
If you eliminate the vent as the cause, you're left with a bad diff design, a poor prior repair job, or the use of poorly manufactured replacement seals ... all of which seem unlikely.
Someone needs to volunteer to remove their vent and leave a gaping hole to allow their diff to breathe and see if that fixes it. Anybody?
