Can anyone identify this knock, I just bought my 2011 f-150 5.0, while driving it I got a low oils pressure light witch didn’t bother me i was over my oil change and I thought maybe that’s why I got the low oils pressure light so I parked it then the next day I started it to see if the light was still there and that’s when I started to hear the knock, I changed the oil and started it again to see if it still made the noise and it did, I’m not leaking any oil anywhere I just need this identified so I can fix
