try the spring and plunger and 2 o-rings on the retainer in the oil pump. Very common and you don't have to pull the pump or anything. Next would be piston oilers on the right side of the block.

I have seen it many times. Many times just after there has been some engine work done to it.Just remove the 5/16 bolt at the bottom and pull punger and clean it.
