Exhaust mani studs

[Notstreetlegal]

Well i got a broken stud on the mani and another stripped one how can I get these out whats the process using the ez out drill bit I really dont wanna take off the head again just after putting in my arp head bolts and mitsu 90 mm. That will be a pain in the ass plus I'm tired of depending on others for rides especially from work. Walking and looking at those slow hondas and saying to myself I maybe walking but atleast I dont have to deal wit 2-3 hp gains off 400 dollar mods is getting old I rather be showing them what 400 dollars can take me.

I tried the ez out method. Didnt work for me. The damn bit snapped off in the stud too! Ended up having to pull the head and take it to napa. Plus replaced everything when off. 600 bucks worth of parts. Not too fun.

You know, I have the same exact problem. It just so happens that I was 2 nuts and an oil change away from driving my car for the first time in 6 months. Surely there has to be a better solution than 600 bucks.

Did it break off in the head? If it sticks out of the head a little you can use a stud extractor. Sears sells them, it uses a cam lock type thing and grips the outside of the stud.

If you stripped it out of the head you can put a thread insert in, we did that on our Talon. Just dont really torque it down to tight, and make sure you use some loctite on the insert.

Thats my best suggestion.

Unfortunately it broke off inside. I'm going to try the EZ-Out just because it is worth a shot. I'm just wondering if you guys that tried it used the reverse drill bits or the little rectangle things. This is the second bolt/stud that has broken in my quest for a running car. I think it is a sign or something. Beware, might be a 95 Talon TSi AWD up for sale here pretty soon.

I think we just drilled ours out. Just make sure you go striaght, and dont go past the stud because there is a water jacket behind it. Then tap and use a thread isert so you can use a stock stud.

If you miss and drill into the head, or break the EZ-out you are screwed. It is a lot easier to just remove the head and replace all of the studs with new ones. If one broke now, who says another won't in the near future?

So I guess I'm pretty much screwed on this. My dad decided to try and drill it out while I was at work yesterday. Everything was fine until we were refilling the fluids and found out he hit the water jacket. Anyone know how to fix this or where to even take it to get it fixed?

Once you drill into the water jacket you are pretty much fucked. I did this (drilled into water jacket) once about 5 years ago and used JB Weld to seal it up (gotta get it pretty thick before you fill the hole) and then put a heli-coil in there and it's still on the road today with the current owner and have not had a single leak.

You can try that or you might as well look for another head.

I have a bunch of 1 and 2G heads already rebuilt in stock. If you want to bring the car down and get it done right, er, I mean, get a hack job done by me, then give me a call anytime 719-243-5305. We do a lot of this kind of work.

So now you have to possibly buy another head, which is why it is usually easier and cheaper to remove it and do it right. I can possibly save your old head by upgrading the studs to a larger size. This will fix the f'ed up hole you drilled into, they are stronger, and they are all new/heat-treated. If you have the money and want to save your old head, I would very highly recommend doing a complete rebuild. I'm sure at least the exhaust guides are worn, the valves are a little leaky, and the valve seals are leaking.
