about a week ago i was at the track and had a nitrous backfire when it occured my oil pressure pinned and it doesnt go back down i havnt replaced the intake manifold yet to be able to start it back up to see if it will stay pinned while its running i just thought i would ask if its normal after a badass backfire like that for the oil pressure to pin. or maybe its just stays where its at so you kno what happened when it shutdown.. or maybe its sumthing else im not sure at this point does anyone know anything about this? thanks
