Yeah, the heat load will effect it without a doubt. Thermal expansion/contraction could expose a leak. It's also why i'll often stress test the system during the second stage. One to get a sense of the kind of temps i'll get and two, to test the loop. I'll also take this chance to bleed the loop as well.

All another reason why not to leak test outside the rig.

The general census is that you should leak test for at least overnight. Personally I only leak test for 15 minutes. Wrap paper towels around fittings, sit, wait, double check for leaks and if not then I just put everything back in and use it. Then the same night I'll disconnect everything and let it run overnight.

I usually leave it for around 24 hours, every time over night (I like to do all my modifications in one sitting, and therefore after I finish I usually go straight to bed biggrin.gif )

And how I detect the leaks? I wrap very thin layer of paper towel around critical fittings (sometimes I help myself with a tape) and if a leak appears, the thin paper towel would be clearly wet, exposing the leak.

Here is a nice photo biggrin.gif
