Good morning. I'm currently battling with an oil leak, and I am curious of its possible source. The oil drips off of the edge of the differential (a555). I have tried the axle seals, since they looked wet, but the oil is still dripping. (After sitting a few days, the oil spot is about the sized of a soft ball.) I am curious what other sources for this drip could be. The return line for the turbo does not leak, nor does the rear main.
I haven't confirmed whether the input seal is leaking, speedo sensor, etc. are leaking. I'm just curious what other sources there could be for the leak. Any pointers would be appreciated. Thanks!
