My first time finding your site--terrific! 20+yr mb, bmw, porsche geek. Bouht a 94 c280 for my wife to drive. Has a horrible oil leak, looks like from the back of the cylinder head. My independent MB mechanic tells me that MB is aware of this and may repair at some, if not all, cost. Car has about 60k and perfect service book AT MB DEALER. Suggestions appreciated. TIA. allen
