Cracked header @ AIR tube flange
The AIR tube flange coming off the passenger header (1" 7/8 Kooks) has cracked right at the base. AIR system has been deleted already. Can this be fixed with the header in the car or am I going to have to remove it?
TIA
P.S. What is everyone's thoughts on running 87 octane? I noticed we didn't have one of these yet today.

Also, if they are going to use electric welding, be sure to disconnect your battery first as a precaution to protect the pcm.

You'll start kicking code(s) if you just remove stuff.

AIR system has already been removed and the codes deleted.
I remember reading something about how a block off plate causes heat to build up and weaken the weld at the base of the fitting, thus causing the crack.
My main concern is whether it's something that could be done with the headers installed. PITA to remove/install them.

If you can't find the small size freeze plug (aka "cup plug") at your local AP, many automotive machine shops keep them on hand in a variety of sizes.

That's a pretty good idea. Well, I'll bring it by an exhaust shop on Monday and if they want some insane amount to cut/weld, or if there's not enough room, I'll just do what you suggest.

Brought it by a shop, they said the header would have to come off in order to do any welding work, which is lots of $$$ in labor of course. Going to just put in a freeze plug as LongStarFRC suggested.

If you do remove the small tube and go for a plug, be sure to not get the hole too large as a tight fit would be really important come time to put the cup plug in. Maybe even consider tapping threads and screwing in a brass screwplug would be the way to go too. Your working with tubing though, so that could be tricky due to the relative thin-ness of the material.
Let us know how you make out.

First off don't freaking cheap out and buy 87 Octane for the Vette -
Now as far as the Air Tube goes just take it to a muffler shop you trust and he should have no problem welding up the stainless steel on the the header while on the Vette!
Thanks,Matt

I'm going to take it to a different shop this week to see what they say, before I get my hands dirty. The shop I asked today was a general 'vette shop, not an exhaust specialist.
We'll see what they say. If they agree that it can't be done in the car, I'll either try to cut it off and plug it, or try SoDiezl350's sealant, till I have the time to take the header off and get it fixed properly.

Was joking about the 87 octane since there's a thread literally every day about whether 87 octane can be used or not.
