Exhaust Stud Replacement

[HondaBoy]

i'm going to be getting a header here soon and some of the exhaust studs are broken off. so i need to get those fixed before i put a new header on. how do they come out of the cylinder head. i've looked in my repair manual but cant find anything there or here on the site from what i've searched. anyway, a simple explanation of how the studs are taken out would be helpful.

I think you'd have to tap them out. Basically it's like drilling them out with a special tool set that will create new threads along the way. I don't think a Tap and Die set is too expensive...

you mean like helicoil? my uncle used that for his spark plugs since the threads got all jacked up....worked fine...oh yeah he has a turbo mazda.

umm how much of the broken stud is sticking out of the head? If its enough that you can get a pair of vise grips on than do it and back the stud out like you were unscrewing a bolt. If its broken off flush than drill and tap it out

nah, i can get it with vise grips

If you can get 2 nuts on it thats how i get them out. One nut will jam against the other.

Other wise grind it flush and try a left handed drill bit and then an easy out.

Steel on Aluminium can be nasty to deal with.

they unscrew just like bolts.

This is how I have always done it, one exhaust nut on backwards and the other one place on the proper way then you usrew them.

If the vise grips don't get it out. Don't think there is enough threads to get two nuts on it. Some other things I've done. Hacksaw the stud off even, hit the stud in the middle with a punch. Drill with 1/8 drill bit, then use easy out on it. If that don't work, then use left handed drill bit. Sometimes you have to drill the the stud out & use a heli-coil if the stud doesn't move. One other trick is to weld a nut on the stud & back it out. Good luck...

i will probably use the method of two nuts locked together. thats worked for other things i've done and will likely work for me best. when i do get to replacing the studs, should i use some light duty thread lock? i'd think so, but i would rather be damn sure. i have some that i used when i put my oil filter base back on with new hardware.
