Went to the Ace Cafe meet last night and gave the car a good drive home after sitting on the North Circ in road works (at 10pm on a Fri night?!?) for almost an hour.

Got home after some high speed driving noticing a strange smell and there are some drips of oil coming from under the diff (the smell coming from the oil dripping on the exhaust). There's no noise from the diff.

I have checked the bible and it says it could be a blocked condesor pipe, I've had a good look under the car at the diff but can't find any breather pipes, and the oil seems to be biased to the offside of the diff. The car was serviced a month or two ago with new diff oil and this was the most aggressive drive it's had since, so could it have been overfilled?

Does anyone have any thoughts as to what this might be or have any good pics of the BTR diff?

Cheers,

Chris

If its coming from one side it could be one of the output shaft seals, i've not seen / heard others complaining of this particularly so i dont think its a common failure. There is a breather pipe on the diff to allow for heat expansion of the air and oil which could potentially spill over if over-filled but given the usual level plug type filler that would be a bit difficult with the diff on the car.

consider this another occurence

Unusual minor oil leak from diff, biased toward offside. Can't find breather. Anyone know if/where it is on a BTR diff?
