The MGB 5-main engine represented a huge technological advance - the "Archimedes Scroll" oil control threads at the rear of the crankshaft were replaced with a conventional rubber lip type seal. We have offered an OE type single lip seal for years under part #120-820, and they work well. However, seal technology has advanced considerably since 1965.

This is a lip seal of improved design, and it comes with an installation sleeve (for use when the crank is in place with the backing plate installed). This is a superior alternative to the OEM type lip seal. It is simply better at doing its job, and it should last longer.
