I've noticed a pretty horrible smell from the second cat burning oil. So I dianogsis it as being the rear output shaft seal since it was soaked in oil. So I had it changed and it's still leaking a bit I think. Is there anything else around the seal that can leak? The smell and smoke is less, just hoping it doesn't get worse and it's just left over oil burning off.
P.S, the car drove fine before and after the change with no noises. It's a 2002 Legacy L wagon 5MT.
