Hello D.J.; If your system ,"blew a hole in the condenser"(ie. discharged under pressure) you probably lost most all of the oil with the refrigerent. In any case, you would not know how much was left, and how much to add to the system. If it was my 940, I would remove and drain the compressor, flush the condensor,lines, and evaporator and then install a new oriface valve if it has not been done in 3-4 years. Then deep vacumn, and add the Pag 100 ( total 7.43oz for the system) and re-charge ( 134a , 2.09 lbs).
