1997 A8 Quattro leaking oil
#19
Re: Can you give more details. I have the same oil leak also. Hoping to fix it soon.
My UK 98 32V S8 had a large oil leak onto the alternator bracket, apparently from the region of the cambelt idler pulley carrier plate. It turned out the external bearing of the oil pump shaft had broken up. This is the *lowest* pulley on the cambelt, but the oil was tracked up by the belt/ spun up by the pulley, and dripped back down. Replacing this (and the shaft seal behind it) cured the problem. The 40V motor avoids this by having an internally driven oil pump. There seems to be no gasket, or source of oil, higher up, except for the camshaft seal (which was replaced as a preacaution).
