compressor blows oil plug

I suspect a blocked oil fill tube cap vent.

I also suspect that you've got badly worn piston seals, and a great deal of compressed air is blowing by them into the sump.

That air cannot get out, so it blows out the oil plug.

See the troubleshooting pages that apply for more help.
