Default Is my intake manifold damaged?

Hi all,
While trying to remove the clamp on the idle stabilizer valve where it connects to the intake manifold, the metal cylindrical piece between the hose and intake manifold just popped out of the intake manifold! Is this repairable? How am I supposed to reconnect the metal cylinder to the intake manifold in order to reconnect the hose?
The metal piece was so loose, I have no idea how it was even holding on!
Here's a picture to better describe the issue. Any help would be very appreciated!!
Thanks!

If i remember, they are press fitted, so a JB weld and a hammer might do the trick.

+1 on JBWeld
Use a small block of wood between the hose connection in the ferrule and the hammer or use the wooden end of the hammer handle and push it tap on the hammer head.

In operation, there is minimal force on this connection. Probably pulling off the hose is the greatest design load it will ever see. If it takes a little bit of force to tap it in, then the friction should hold it. JBWeld is a little bit "gloppy", if you think you need an adhesive, you might want to consider Blue Locktite. Or even 5 minute epoxy. What you don't want is excessive sealant pushing out on the inside and breaking off later into the air flow for your cylinders.

Starting back 1/4 inch from the end to be inserted lightly cover the outside with RTV, tap into place as others have instructed and wipe off excess sealant. JMHO

I would use some grit paper on the tip and the bore to remove the old adhesive,
mix up some JB weld put a lite coat on both parts mask off where you don’t want the epoxy then tap it into place use a q tip to remove the excess inside the tube

+1 on jb weld. These were forever popping off on my 951 manifold and RTV wouldn’t hold them. Lightly sanded fitting and hole, a bit of JB weld and done deal.

If you do scrape or sand it, perhaps use a vacuum cleaner to suck the grit out before adhering.

When it happened on my 951 intake, I installed with 5 minute epoxy and then became worried it would fail under boost in the middle of nowhere. So removed it before even testing it. Then I tried a second formula like JBs, but couldn't shake my fear. Then successfully attempted to tap for a metric bolt that didn't require drilling because diameter was suitable already, and shortened the bolt to make a plug, using a saw to allow a flathead screw driver... and then sealed threads with anaerobic sealant (something like 510 permatex), but this on an engine with an idle stabilizer delete. Just showing another angle on solutioning, certainly not saying it's better than what the others have suggested. Let us know your results!

Happened to me too. Cleaned the nipple and the bore well, used Loctite 680 bearing retainer.
