good idea...take it to a dealership. They will really help you out...haha

The welding thing may work but thats pretty difficult stuff. i don't know if you'd really have room to get a good weld on it w/o actually welding over the manifold itself. The way to do this is with the correct tools...easy out/ extractor. and like that other dude said soak in with something...wd40...blowtorch that sucker too.

Honestly I still think this is way more work than its worth. 30-40 bucks for a new one...maybe less if you bargain hunt.

This is simple stuff with the unit on a bench. Try fixing a broken-flush rotor housing exhaust stud with the engine installed.



Soak it in PB Blaster and start with a sharp left-handed bit. If it isn't out by the time you've got a hole for your extractor (i.e. easyout) try the extractor. If all this fails then drill it out completely and re-tap.
