hello to all.i have a 1999 a4 2.8 quattro/30v. i had a oil leak from the front of the motor. disassembled and it was the frt crank main seal. i replaced it and reassembled. ran the car for about 15 minutes and the leak is still there. the odd thing is that the seal was blown out of the flange on the first disassembly. i suspect the same has occurred again. any ideas why the seal would get blown out like that? someone had mentioned the suction jet pump but i replaced it about 1 year ago. i need some suggestions so i can correct the issue. any help will be much appreciated! thanks
