Ok I took the oil pump off and cant find anything wrong with it...the relief valve piston slides up and down freely after removing the spring, and the gear meshes tightly. And the o ring wasn't pinched. However, I had a spare pickup tube laying around, and it does slide in with pretty much no resistance, considering the new o ring is a tight fit, but looked like it was doing its job. The pump, and the oil filter had oil in it, but the area right around the cam was pretty dry.
Also, I took the adapter out of that oil port and it had a little bit of an oil film on it, but not enough to reach the sending unit.
Im puzzled at this point. Any help would be greatly appreciated.
