So I bought a truck that already had a built motor in it don't have alot of details on the build but it is a 454 when I took out for a spin oil pressure was great 50 PSI + so i load it up bring it home and putt around in it for the day and that night I decided I wanted to see how it launches so I took it up to the stall and launched it keeping an eye on the gauges the whole time and after I shut down I look at oil pressure and it's at ZERO so I shut down the truck and get out and look around well Teflon oil pressure line got on the header and melted shut no big deal put a new one on and been having low oil pressure and recently gauge will read ZERO running in a straight line but when you turn a corner it will shoot up to like 50 anybody have any ideas what would cause pressure to go up when turning (heard of it going down but not up?)
