ok so I got my liquid flux in today and re did the reflow so fingers crossed this will be fixed for good. When I was browsing the web I also came across a neat design for an air nozzle holder which I will need to take some pics of and post, it helped a lot and was much sturdier then the clamp set up I was using before and was fairly cheap to make ~$5.
Again thanks for all the advice, this site is very helpful.
