Hey Gang!
For those who have seen this: does it look like my coolant pipe is about to pop out? Nothing is leaking but it doesn't look anything like the fitting on the other side...
I might have gotten lucky trying this project before a failure!
Yes, that fitting is ready to pop. Is the engine out?: You can remove it, clean it up with emory cloth to remove the cooked glue and re-epoxy. I would put a M4 button head stainless fastener (drill and tap) so that it doesn't ever come out. Do the other side also. It looks like there is white coolant residue showing.
Thanks Guys. Yes, I have the engine out. I started this project seeing if I could pin the lines with the engine still installed, but found I could reach 5, maybe 6 fittings, but not the 2 under the oil cooler. I was momentarily considering pinning the ones I could reach and hoping the others would be fine! Glad I didn't go that route! So engine is pulled and with the intake off, I found that fitting. In the limited space that's there, I tried to wiggle it and it didn't easily fall out, but I'll undo more stuff and see. I'm so glad I decided to do this!! Mine is an 03 with 90K miles that might see the track one day...
If that fitting has backed out a bit (or more) wouldn't there be some seepage or leaking around it already? Or has seepage/leaking already been seen there.
There wasn't anything leaking at all in the area. I would have thought it would leak a bit, too, but most accounts of these lines failing appear to be all or none events!

I think there is evidence that they can leak and not blow out.
It seems to me that if your fitting has backed out by some amount then that obviously means the adhesive seal has been broken and therefore there should be some evidence of seepage/leakage.
Since your engine is out and you plan on tracking the car, I think it is a great idea to seal and pin all of the fittings. My specific point is only whether or not the fitting in your picture shows signs of actual movement (backing out).
It DEFINITELY backed out. Wow, got super lucky on this one as there was zero sign of leakage. I gave it a firm pull with a hose separating plier and pulled it right out.
Got it cleaned up and epoxied and it'll get pinned. This experience has made me a believer that all of these need to be pinned, whether tracking or not (mine has never seen the track).
dark adhesive was what was holding it in still...
cleaned up prior to recementation ready to be pinned once the epoxy dries
Does the fact that it pulled out easily indicate that it was backed out, or that the adhesive wasn't working? From the before and after pictures (installed versus pulled out) it appears that based on the glue line that it was in it's original installed position before being pulled out.

It was half-way out, not in its original position. It should look like the other fitting in the image I attached above, where the hose is right against the part, not spaced from it.
And now that I see how everything should be, the hose below the alternator was pressed against the engine case due to the dislodged position towards the rear of the car; usually there's about 3/4 an inch of space between the hose and the case, so even though you can't see the fitting without the intake removed, you can see the hose's relation to the case which would indicate it's scooting out if there's no longer space there.

no the glue is great, move along you don’t track your car this doesn’t pertain to you.
Yea, you can clearly see it's half way out as indicated by the mark on the fitting. Good find. That would've let go and dumped all the coolant. Nice job!

Am I about to lose this coolant pipe?
