Ac compressor lockes up.bad compressor or blockage

[Jrp79]

94 mazda b3000 ac compressor keeps locking up. Had a leak at high side valve so replaced it. Added 4oz of pag oil any 16oz of freon. About 15 minutes after it was filled ac compressor locked up.shut ac off and pulley spun freely. Could also turn the clutch by hand so I dont think my compressor is bad.orifice tube had particles but didnt look that bad but going to replace it anyway. Also going to try to blow air through the system and see if it feels free.
any suggestions as to what else it could be?

Gonna rent a vacuum from my local parts store.I never had to vacuum a system.is there a special way to do it? And by pulling the high port valve off and pouring the oil there a good place?
Also if I add oil before I vacuum it will the oil stay in the system

Please, I'm saying kindly as possible, don't try to fix it and find someone or place to help you, compressors are not cheap!

this may be some help.

Ok.I blew air through the system and not much flow so i disconnected all the connections and used liquid flush then blew it all dry (system hasnt been used in a while).since I did that I got a new compressor seal kit and new dryer.I took the compressor apart and cleaned everything and resealed it.I still got the compressor off and spun it a few times (alittle resistance at first but didnt want to spin to much with no oil).now where on the pump do I add the oil and how much do I add to that and the dryer?
