Front crankshaft seal rides on snout of crankshaft to keep oil from coming out of the crankcase on 7M. The only time you need to use FIPG on the crank snout/crank balancer securing bolt flange is when the front crankshaft seal rides on the crankshaft harmonic balancer, like on the Ford Duratec engines. Two different designs.
Wrong!.
It rides on the pulley, which has a ledge just for the purpose.
And this photo shows pretty clearly that the seal is much larger diameter than the snout.
