K11 Preface Lambda Boss needed asap

Lambda sensor is broken, so needed to replace but upon unscrewing it, the boss came with it and i cannot get them apart since its rust welded. Anyone know where i can get a lambda boss? Need it before monday as MOT. This image is from a spare manifold which i cant get the boss out. Cannot use this manifold on the car either otherwise i would do.

That's a bummer.... Can't you weld a nut with the same thread size and pitch?

a slit in the side of the boss,then hammer a flat screwdriver into the slot to open it up, that will free the thread off

I broke off the parts you are about to loosen. Also two out of eight studs. I cemented it (airtite) passed MOT and now drive around with lambda connector loose so it is stuck in open loop. But if your lambda eats threads then you might end up breaking studs to get manifold off so that is kind off worse to worser case scenario and mine hasn't ended yet
