Crank and camshaft oil throwers

[wild_willy]

I am currently rebuilding an engine with a pressure fed 1 1/2" Phoenix crank and a modern rear oil seal with a speedi sleeved flywheel.
What is the recommended approach to using the old oil slingers/throwers once modern lip oil seals are incorporated in an engine build? Do we just bin them or are they still a must?
Many thanks

You need the thrower and related oil drain hole. It reduces the amount of oil at the seal. I found without the seals leaked more oil.
