It happens to me once, that the oil pump shaft splits in 2 and cuz a litlle pice of rust from an overlook rusted windage tray stuck in the oil pump, and sized the pump spliting the shaft in 2, and no oil preasure, good thing i just caught it in a second and shut it off til change the windage tray and the oil pump after cleaning the engine inside and out!

By the way MECHANICAL OIL GAUGE IS A MUST IN ANY PERFORMANCE ENGINE IN A VISIBLE PLACE
