<VV> oil pump

I had this happen one time, cause was distibutor shaft had sheared thru the 
cam-to-distributor drive gear pin hole.  Engine still ran and friction at the 
fracture surface in the gear provided enough drag that the oil pump still 
pumped (weakly) preventing the complete loss of oil pressure and engine demise.  

Easy to diagnose, if this is cause in your case.  Just note distrbutor rotor 
location (for reassembly) and remove distributor.  If shaft has separated you 
will be able to pull it into two pieces.
