I removed the sender from the block and hit the starter. After 3 seconds,
oil came out of the opening and went all over. I cleaned the
oil up and reattached the sender but never saw the
oil make it up the tube. I should have been more specific. I have oil but it doesnt appear like there is much. When my dad fired up this engine, I know it had good oil pressure. This was around 4 years ago.
