 Early Lotus Turbo Esprits used an external, inline thermostat. If that were used as the one-way valve, it would be closed on cold starts when the electric pump would be used, and open when hot. Just a thought.

Oil thermostats were deleted from later Turbo Esprits. The thinking was that the gain due to having a thermostat was offset by the flow restriction it added.

I suppose something similar might be said for a one-way valve.
