Audi 4.2 FSI V-8 Engine: Can someone find the Audi / VW part number for the O-Rings that go on the ends of the coolant tubes, located INSIDE of the timing chain covers at the rear of the engine? If I recall...the diameter of the O-Ring was something around 30mm and the thickness was around 5mm or so....these are just approximate sizes of course. Thank You for your help Audi folks...! Sincerely; Jeff
