LOL! I've been told many times to stop using snoop. But it works so well... And his leak seeker did not find those 2 leaks :wink:

Snoop doesn't work at all on hot surfaces like inlet and detector connections.

If you must use a liquid try a 1:1 mix of water and isopropanol. It's viscous enough to work but should not contaminate anyting.

MUCH better than Snoop but it still doesn't work on hot connections.

Ha! I though I would get some sort of notifications if there where posts on my threads!!!

You are right Snoop doesn't work on hot stuff... but my bosses will not let me buy a 1500$ leak seeker... So I make due with what I have. I may try the isopropanol mixture.

One temperature programmed run with a leak in the system can destroy a polar column - a question for your boss; how many columns do I have to destroy before the leak seeker would have been a better investment than a bottle of Snoop ?
