So I'm sitting in a McDonalds drive-thru and the oil gauge on the Atari dash hawk goes to no bars in drive and one bar in neutral.since my engine work that is in my sig, i have put about seven hundred miles on the engine and the oil pressure atty a standstill is usually two to three bars. What is going on here?? Could the new oil pump or Underdrive pulley be to blame? The car's oil pressure is fine at road speed, only at a standstill does it get low. Checked the oil which was changed about four hundred miles ago and it seemed fine, good color and level.
