The correct information follows:
The tightening torque for plug (5) in the former 9S9994 Oil Drain Assembly is 110 15 N m (80 10 lb ft).
--------------- END SUPPLEMENT ---------------Reference: Service Magazine; May 6, 1991; Page 11; "New Oil Drain Plug And O-ring Seal Used In Oil Pan Groups" on 3400 Family of Engines.Description of Change: A new oil drain assembly and O-ring seal are used in oil pan groups. The new drain and O-ring seal will better resist the effect of thermal cycles and vibration than the former oil drain assembly and gasket. See Illustration 1. This will help prevent oil leaks.Adaptable To: The new 4P0519 Oil Drain Assembly and 6V3830 O-ring Seal are a direct replacement for the former 9S9994 Oil Drain Assembly and 2M9189 Gasket. The tightening torque for plug (6) in the former 9S9994 Oil Drain Assembly is 110 15 N m (80 10 lb ft). Tighten plug (2) in the new 4P0519 Oil Drain Assembly to a torque of 70 15 N m (50 10 lb ft). Be sure not to over tighten the plug in the new oil drain assembly.
