When I charge my ac I'm not sure but After a while of running the freon blows out the high side port. What can be the cause of that. Any help is appreciated.

 

Could be any number of things...

How are you filling the system?

Its best to take it somewhere that uses a filling machine to empty the complete system of all the air (vacuum) and then refills it with zero air in the system... Maybe..your over pressurizing the system? Did you add any of the lubricating oil once the system was empty? ... Could be a bad/worn seal?

 

I recently replaced the ac compressor. I put oil in it then. But when I charged it after a while of driving it would just blow out instantly and instantly stop.
