rear diff VENT?
Reply #6 –
The vent on my 8.8 is on the passenger side top towards the wheel. I replaced my differential cover a while back used a B&M cover I found on ebay. Only problem I had was getting stupid. The cover has a drain and fill plug but I forgot about the fill plug on the drivers side front of the differential. Filled the rear end using the fill plug on the cover as a gauge. Took the car for a drive and was smelling gear oil. Parked it and I had gear oil all over the gas tank cover. Then I remembered the fill plug on the differential which is quite a bit lower than the one on the new cover. Drained about a half quart been good since. Felt like an idiot.
