A lip seal assembly provides an axially adjustable seal between a rotating shaft, such as a crankshaft, and a stationary housing, such as an engine block. The assembly includes a generally ring shaped retainer circumscribing the shaft and having a hollow, cylindrical cavity therein which receives a slidably positioned lip seal mounting member. A plurality of ring shaped spacer gaskets enable the lip seal to be axially adjusted within the cavity such that the point of engagement of the lip seal with a running surface of the shaft may be changed.
