Default Can i epoxy this?

I think this is the culprit to all of my high idle issues and problems. I can twist it back and forth about an 1/8 of a turn or so. Ive read where you can take a long dowel or pipe and knock it out from the inside but once i get it out im not sure i can make it any better than it is. Why cant i just epoxy it to the back of the intake so it is permanently sealed in?

Thanks for any help.

its supposed to twist because it is removable. i highly doubt its leaking. you could try twisting it, removing it and then seal the oring up with a new one or use a little rtv

Umm, it's not really removable. Sure you can knock it out, but the tangs that secure it will likely be broken off. When running, engine vacuum will suck the "plug" against the manifold while compressing the o-ring. You could easily test for a leak by waving an unlit propane torch around the joint, if RPM's pick up, then it's leaking...

That was my thought as well. Everything ive read says you can remove it but "good luck" because you will probably break it or your manifold. lol. I just cant help but think its leaking because of how loose it feels.

I also say it's highly doubtful that is your vacuum leak. I would put it back together and spray something back there and listen for a idle change. Vacuum leaks can be such a ***** to track down.
There is a vacuum line that runs along side the passenger side by the valve cover. It is wrapped in foam and is a two piece line that sometimes separates when removing the intake but is hard to hear and won't surge when sprayed because it's wrapped in foam. Something to look into, let me know if you need a picture

If you wish to seal it use Rapid Fix epoxy. That stuff works great on the nylon intakes.

That plug should be quite snug due to the o-ring causing it to be a tight fit in the intake... so it sounds like the o-ring has failed...

as was said, there are 3 tangs keeping it from un-twisting, this is what makes it difficult to remove without damaging it and/or the intake;

if you epoxy it to the intake, you are not losing anything because it is not supposed to be removed, and you have everything to gain if it was leaking.

highly unlikely. but if you are certain then just seal it with epoxy. no harm in doing so anyway.
