Audi 2.8L V6 Rear Crankshaft Seal Leaks After Replacement
Oil may leak from the rear crankshaft seal after seal replacement due to the seal lip rolling while installing the new seal.
This conditon affects 1996 A4 with 2.8L V6 (Engine Code AFC).
When replacing the seal (seal is supplied pre-installed in flange):
Seal/Flange Part Number: 078 103 171H
Flange gasket Part Number: 078 103 181 (must be ordered separately).
Caution: Part numbers are for reference only.
• Carefully remove installation tool that comes with seal and apply a small amount of engine oil to the inner lip of the seal.
Note: Lubricating the seal lip will ease seal installation and reduce the tendency of the seal to roll as it is being installed.
• Carefully reinstall the seal installation tool.
• Install oil seal and flange with new gasket.
• Torque reusable flange bolts to 7 ft.lbs. (10Nm).
