Surf 1KZ motor oil presure

Does any one know the hot oil pressure range for the above motor in an early 3.0 ltr diesel motor? Also what are the usual problems with this motor? Is it the oil pump or the bottom end bearings that can cause a low pressure? Thanks.

Hi not sure of the preasure range, but I did have an issue just before oil change with mineral oil after alot of offroad use, think it was starting to be brocken down, could be worth thinking about, also think the sensor can get very dirty try a flush will be a cheap way to see.

Good oil pressure will be something like 150-170kps at idle and 350 -400kps at 3000rpm
20-60lbs in round figures
