When the engine gets up to temp. the oil pressure decreases ? When I go to idle the oil pressure needle drops off completely, it comes back up when I pick up the rpms. This is the factory gauge with new sending unit. When I first start and run it the pressure reads about mid scale on factory gauge and only drops a little at idle.
I temporally connected a line pressure gauge and it reads 15-18 at idle when hot but at 4k it only goes up to 28-30#. Engine sounds ok, no unusual sounds from valve train at idle
What do you think? Are these ok ? What should it read Need new oil pump?
With line pressure gauge it never drops to zero.
