Where is it leaking?  The seals are on the shaft, and the leak goes back into the engine, so a bad seal would just fill up the sump, not leak externally.  Externally there are the input and output fittings and the pressure relief valve.  Same with the compressor - a seal leak will put oil back into the engine.  Externally there are only hose fittings.  Of course the base gaskets can always leak.

The o-ring on the pressure valve is where most leaks are it takes a special o-ring  Parts for Pumps in Tn has the seal kits they where 11 bucks a few years ago probably 20 now lol  

If it leaking on top where the hold down pin for valve is located just a o-ring is needed and that repair can be done without removing the pump finding the square o-ring locally is the problem,fwiw that is where most leaks are on a GM

most likly external,thats how i spotted it,pump is just wett,have not started motor in a awhile so i see it just its sepping out,possible onto the compresure as well  most likely base or covers on the pump,it is a clear motor oil ,not black (engine oil) or red (tranny oil) i use 10w40 in the power steering!
