Broken weld on the intake
The car started idling really high. Headers also got really blue. Eventually found this. This is the back on the intake. It saw ~20 lbs a few times when I first built it, until I got the gates set up properly, then ~10-12 lbs since for the last 1000 miles.
it was only last couple times out it started idling high.
You can see how blue the headers got. Running lean obviously. 😳

Just my $.02
2 things come to mind.
1. Metal is very thin.
2. Sumting Wong welded only 1 side.
I would consider at least removing the thin end plate, removing the old weld bead, and adding something heavier.
Welding over prior weld is not going to enhance the reliability.
A math exercise: area x pressure.
Also, "only 10psi", is just the starting point!

I tend to agree. I can weld it on the car, so I’m going to give it a shot and keep an eye on it.
If I have to remove it I’m going to just replace it.

Haha
I’m sure you’re all right.
im going to weld R up and give it one more chance.
if it gives me any more issues I’ll be back to discuss another option. It has to be aluminum though. The appearance is important to me.

While you're in there, position a 1 to 1.5" .090" flat strip across the back panel. A bead on each side should to keep panel from flexing so much. That panel is likely 30+sqin. At 20psi that's 600lbs of force jacking with it.

It will likely be fine once you reweld it properly. Those are VERY often "cold welded" This gives them a pretty appearance and is cheaper and easier to train people to do. Its not near as strong as an actual weld where the heat penetrates deep into the metal. (more like brazing) Though it may happen again somewhere else once you weld up that area. Most of the intakes went to thicker material. Maybe thats an old batch? See if you can mic the metal thickness. Might be better off ordering the newer thicker material manifolds... Believe the newer ones are 3mm thick. The one I had was roughly that anyway.
Good luck! Let us know!

Had it Tig’d and holding up so far. Haven’t driven a lot, but beat on it pretty good when I did.
it is a older version ~5years old. That back plate is definitely not 3mm, more like 1.5mm.
