Hi, My Dad's wagon was taken into the dealer for its regular oil change at 68k miles. Afterward we noticed a smell and some oil drops on the driveway. Gave it about 5 days but after it didn't stop, brought it back to the dealer. They say it's the oil separator cover leaking. My question is since there's only 68k miles on it and it's driven by a little old man (and his wife), should we just wait until something more major needs to be done maybe, say another 30k miles and have the works done on it? Can the leak be tolerable until then? Or is it anticipated to get worse and more of a problem? Thanks, Bill
