Hi, I'm providing help over the phone for a friend of a friend installing a 1.9 into his Caddy. It should be a pretty nice ride once complete. He even purchased a Giles pump for it. Anyway, he has decided to go with a T3, but apparantly it has a massive oil return flange compared to the new oil return line he has. I assume that the line he has was intended for a K03 with a smaller flange? Is there a specific oil return line he could order from VW that will properly adapt to the T3 and drain into the back of the block? If such a part exists, and if anyone has a part number I would be appreciate your input. Thanks.
