Ive got a 2014 insignia, i removed the egr and throttle body to clean, when removing the throttle body bottom screw the metal housing came out with it, i never thought much of it until i was putting it back on, i pushed the metal part back in and screwed all bolts back in but the housing wouldnt sit flush due to the metal bit kept just coming back out whilst i was tightning, does anyone know what i could do?, thanks

Is there room to get a nut on the back of the plastic flange (where the bolt sticks out the back)?
If there is, then remove the brass insert from the bolt (hold it with a mole grips, and unscrew the bolt).
Then refit the throttle body with a flat washer & nut on the back of the flange. You may need a slightly longer bolt.
Don't overtighten the bolts!

In your photo, there is a good length of thread sticking through the insert, and, looking at the other photo, it appears the flange has room to get a nut behind it. You might have to modify the housing a bit by cutting some of the plastic away, and also modify any nut by cutting some of it away on one side to get it in there.
The only other way is a replacement manifold.

so i have found the inserts but no idea about which size, does anyone know how to meausure the size i need?, i know the insert will need to be a little bit bigger so it grips tights into the plastic,

EDIT: would the helicoils work?, these brass ones need heated and inserted

Hi not sure which engine it is but if its any help its an ecoflex, i have managed to fix it using a soldering iron (£8 screwfix), heating the brass insert and pushing it in.
