just a thought, are you still running this showing no oil pressure? have you verified that this is a faulty reading at all as you'll kill the motor if there really is no oil pressure...
My immediate thought with the two problems though would be the oil pressure sender, which is the silver part just below the freeze plug in the above pic. if this is loose/damaged oil could be leaking from here & not registering the pressure correctly. Get that fixed ASAP as the oil pressure & water temp gauges are the 2 most important on any motor IMO...
