Any chance you are using one of the add on external oil feed
pipes to get extra oil to your top end? If so, try removing it and
returning to the factory oiling arrangement. The external oil feeds have
a reputation for causing excess oil consumption in some cars.

pressure around 30 when running over 1 hour; 20-25 at idle;start up
until warm 75 psi; some wet oil blow out present from exhaust-no smoke;
