I would not start your car again until you have pulled the vacuum pump and inspected it.
mine started having low vacuum, and then it took out the chain at 40mph...
pull the pump and inspect it. also inspect the pump cam ramp that drives the pump for wear, also measure any play in the timing device the ramp is mounted to. if all checks out, then put it back together, and find your vacuum leak. 8 is far too low.
