Hi John
The engine number suggests March 1931. The original rear main seal would be felt and thrower.
On the three engines I’ve built that date from this time I’ve replaced the bearing cover with one machined to take a lip seal. Readily available from the Cherished suppliers. I’ve not needed to fit a speedy seal on the flywheel boss to ensure a good surface for the lip seal but I know others have. Touch wood I’ve had no leaks so far.
Unfortunately it is an engine out and flywheel removal job.
Cheers
Howard
