. . . my 200sx AC was working then the dryer blew a seal and sprayed I'm guessing refrigerant or oil not sure if the oil would come out of this or just refrigerant ? . . . .
Refrigerant would vaporize and there would be no trace of it. Oil is carried by the refrigerant and that would leave a slick residue. Is oil present on the receiver - drier and surrounding area? I would expect that to be the case.
. . . I've replace the dryer with a new one, second question 2) do I need to drain the oil from the condenser, . . .
It appears from your description that the system over pressurized and vented refrigerant. The pressure relief valve may be incorporated in the receiver - drier? A close inspection would vallidate this statement.
The system lost some refrigerant oil but it is difficult to determine the quantity. Typically a receiver-drier would hold 1 ounce of refrigerant oil. You do not need to drain any oil from the condenser.
However several important issues on this air conditioning system. Since it is a 1986 model (30+ years old vehicle) it was equipped and designed as an R12 refrigeration system. Has the system been converted to R134a refrigerant? Different refrigerants, different oils used.
Why did the system develop such high pressure to vent refrigerant? Is there some internal failure in the system ( such as dessicant rupture) that blocked the high pressure, discharge side of the system? Did the cooling fan that draws air across the condenser fail and allow temperature and thus pressure to exceed safe upper limits?
. . . if I wanted to put a vacuum on the system does any parts stores rent the equipment to do this? . . .
You would have to check with individual retail auto parts stores in your area if this equipment is provided on a rental basis. It is probably on a store by store basis.
