I'm in the middle of doing a head/cam swap and I accidentally discharged my A/C--took off condensor hose by radiator--stupid mistake . I know air/moisture is not good in an A/C system--will it hurt anything to keep it discharged for a month, or should I try to charge it somehow? Thanks for your help.....

 

Cap it off the open fittings and make it as air tight as you can. When you get everything back together, have the system evacuated and recharged.
