Dixie narco decks
Hi i have had a lot of dixie narco decks and all have a slow leak on the evap. Tried leak detecting but can not find the leak.
I have seen a leak stopping formula that i am concidering using, Has any one tried these?? and if so are they any good?? or has any one any better ideas on sorting these out apart from throwing.

Hi Brian. I assume you've isolated the evap, pumped it up and found it's loosing pressure?
I'm not a big fan of putting anything other that refrigerant and oil in a system, but if the only alternative is to scrap the case, I suppose it's worth trying your leak stop stuff on a couple of cases and see if it works.
Let us know how it goes.

Re: Dixie narco decks
how big are your coils? can you not take them out and put in a water bath with your coil full of nitro to find the leak. i would not like to use the self sealing stuff

I assume you're talking about a stainless steel deck with a copper evap soldered under it and foamed in Brian?

If losing vacuum are you sure that your guage lines are not breathing through the walls, connectors, or the manifold valves.
