98purevil

I have a 98 Cobra me and my dad rebuilded we forged it all out and was ready to dyno and tuned...when i took it to Murillo Motorsport in San Antonio tx it was on the dyno and as they where going though all the gears Murillo heard a knocking noise on the passenger side head of the engine so they stopped the dyno.....well the next day i took the car back home and we start taking it apart and notice that there was no old going to the head at all......i had a new FORD RACING high volume high pressure oil pump put on and the gauge to the oil pump just dropped....can someone help me out or if someone live's in san antonio can stop by to help me with my car.......
