ISR mod leak question
I've got an ISR tube and I realized today that the seals on the inlets aren't airtight.
When I cover the edges of the seals, the idle cleans up and gets stronger. I'm psyched that I found this issue but I'm not sure of the best way to seal up these two valves. I'm enclosing 2 pics to give you an idea. Thanks a lot

When I made mine, I drilled the hole just big enough so I could thread the fittings into the plastic itself so it would fit nice and tight, then I put an o-ring on the fitting plus some high temp def-con on it. No leaks here 
You might want to try putting an o-ring on if you haven't already then spread some def-con/plastic epoxy on it. Hope this helps.

Thanks guys. Is either one one of these the stuff you're both talking about? (just one, or both?) Looking forward to getting an airtight seal! Thanks again

I'd try just wrapping the fitting with some Teflon tape, just wrap it 3 or 4 times, it will take you 3 seconds and you will know right away if it works, you don't have to wait for anything to dry.

Thanks guys. I'm going to pick up some RTV today and some new hose clamps. Looking forward to getting that ISR tube airtight. I also found a loose spark plug yesterday, (cylinder 5, hardest to access w/headers! Damn Reed/EGR valves!) all tightened now with new wires and I can already feel the difference. With this leak sealed I'm looking forward to some nice driving! Thanks again for the tips
