Oh yeah I forgot to ask, After I get the system vacuumed down and know it has no leaks, do I leave the system under vacuum and start adding the r134a, or should I release the vacuum and the start adding the r134a? I have looked but cant find any info on this. And if anyone knows how much oil to add to a completly empty system (ie. flushed completly) let me know.

Thanks
