Answer oil pressure problem

I would think that you need to replace your oil pump or make sure the pan gasket hasn't rotted and fell in the oil pan and is stopping up the pick-up tube.If its not the oil pump then you have a bearing problem,I would start with the oil pump first.Hope this help Ricky B.

Yes i would start with the oil pump. But it sounds to me like the dreaded cam bearings.
