Heres scenario, Was driving Mustang last night and all of a sudden my oil pressure dropped to -0-, I quickly shut engine down and added a quart since it was a bit low, Started car up and it was fine rest of the night and this morning. On my way home it happened again, Pressure dropped, Car read Low Oil Pressure and I shut her down, waited about 15 minutes and started her up and pressure was normal again and was able to get car home, Now I have the dash gauge from Ford and my aftermarket gauge in Center Pod so I know it wasnt a gauge issue. I have no oil leaks, The oil is clean and not burnt, Car still has engine power, The oil pump was bought brand new when I had P-51 Motor put in back in Sept 2010. Im pretty much sure its the pump, but just wanted to share what was going on to hear some of your opinions. The pump is from TSS and from what I read back then they are pretty damn reliable. And I have a weird noise coming from engine so Im assuming its bearing in pump maybe?????
