Hi Greg, the gear pump is positive displacement, besides internal leaks the volume is linear with rpm.
Yes the pressure is high going into the restriction and then low on the other side.
If indeed the relief valve is after the oil cooler / filter then it does not surprise me that the gerotor pump cracks ones in a while, unless there is a bypass valve....If the relief valve is before the the oil cooler / filter then it does not surprise me that the d1 builds up.oil pressure very slow when it is cold.
Again with all the oil problem threads here and other sites I am surprised that I have not found an exact description yet.
