I know there have been a lot of threads about oil pressure and the sending unit but i have one for ya. My oil pressure is very low (0) but only when i am sitting still or pushing on the gas. When i am coasting the pressure goes up (25). Push on the gas it goes back to 0. Changed the sending unit, just had an oil change. So I'm at a loss here. What do you guys think? Oil pump? No real leaks although i did see bubbles coming out of the oil filter adapter... Any help is appreciated.
