so my car is giving me hell currently and i have been trying to find a resolution for weeks and am unable to find the light. the car slowly lost oil pressure and silly me wasn't paying attention to the gauge closely enough and it spun a bearing/ started rod knocking. So i tore it apart changed the bearings cleaned the crank up all nice like. put it all back together in the same day. went to start it up and here is where it gets confusing. while i had it apart i thought that the reason i lost oil pressure what due to a bad pump. so i pull a pump of another motor that i have sitting around and put it on the car. the car still wont make any oil pressure. doesn't make sense that 2 pumps would have the same issue. so i pull the intermediate gear off and spin the pump with a drill and i can get the car to make nearly 10PSI of oil pressure
so i thought maybe the oil pump just needed priming go to start it up again. no oil pressure. the fact that it makes some pressure with the drill leads me to believe its not the oil pressure relief valve in the pan, the pump, or a bad oil pressure gauge. I'm sure that I'm not the only one in the last 30 years to have some funky oil pressure issues. so I'm hoping that someone can help to point me in the right direction.
