Drill enough of a hole to get an easyout in the stud, heat the block around the stud with a rosebud, then carefully dribble some liquid nitrogen in the hole you drilled. Then put the easyout in and it should come loose. You can get liquid nitrogen from a welder supply, they will put some in a stainless thermos for you.

 

the story continues, we took the truck to a big rig mechanic...they are just now getting to it. sent it off to a welder with special tools, sounds scary. we now need more studs anybody know a shortcut to who has them? another question who on earth needs a 12v with fire rings for a daily driver? do any of you guys know anyone who has done this just curious guess the previous owner had lots of money.

 

Big turbo pressures are the only reason to o-ring the head. From what I hear pressures over 40psi are getting into o-ring territory. On the HEMI race cars the gasket and copper wire had to be put in just right or she'd leak.
I know a guy who spit the head gasket at 50psi on a standard head/block.

 

Generally you wouldn't have to worry about something like this unless you're running a bigger turbo, but even the HX35 will put out higher turbo pressures with some of the chips/programmers out now. In the older 12V boosting over about 40 psi is a bad thing and it needs to be done. Sounds like you got hold of a truck/engine that somebody was running a little harder.

 

indeed, had we known we would not have bought it. this is something we didn't bargain for.my son who had to have this thing traded a perfectly good powerjoke that is still running with over 200k <and having been rode hard and put up wet by both my monsters>whil this reliable ,haha,12v is parked for going on 7 weeks. now my new dilemma do we just pust back head bolts we cannot afford new gasket with rings,2nd since the guys put the new one on with out finding out not to first these things are 273 bucks, new head studs are 450 bucks . i am going to sue the previous owner for non disclosure...seriously folks this isn't something you can look at and tell these mods have been done. oh and by the way the guy who did the engine screw up is now in ok BEWARE i will soon post a wanted poster for him what are these pwople thinking?

 

Yep, I know a few guys on here that did it to their "daily" drivers. That daily driver sure can go though!

As far as boost goes, I feel good about doing as much as 70 psi with my stock head gasket, and have done it. I try to keep it down to about 60 most of the time though.
Since it has gone to the machine shop now, I won't bother with advice on the stud removal.

help again it appears that there is only one place in the world that makes head gaskets for fire or c-ring set up and though haisleys is great they are awol at the moment and that is not good for us good for them ,pulling or racing or whatever,we are stuck without truck for two months now....i think i will buy something nobody wants to jack up,hop up, or do any mods to,safer that way. really need any suggestions asap helllllpppp

 

I think you can use a regular head gasket with a copper wire placed in the channel. Just make sure that the wire is heavy enough gauge to squish down and seal, and not so heavy that it does not allow proper clamping on the gasket. Measure the slot and I will find out the correct wire gauge for you if you want.

we are pretty sure that you can reuse the orings we have but we ,my husband, put the gasket on and torqued down without the head being redecked so we now must get a gasket, which is water jetted out for the rings. so ?

 

If you could get a mag base drill that could help. good luck Jim

 

That stinks! I, like some that have alread mentioned, have had great success with welding something that will help you grab whats broken off below the surface. Only different thing I've done is weld the hole of a thick washer to the surface of the bolt and then weld the outside edge of the bolt to the washer. While everything is still nice and hot from welding shoot some penetrating oil towards the studd as much as possible to shrink it a bit and then hit it with an impact. Go slowly with short bursts and if noting happens try tightening, loosening, tightening, loosening and once it starts to free up don't stop. You may break off the welded washer and nut a few times but, take your time keep a cool head and don't give up. If possible, not sure with the O ring machining that's taken place, I'd re-install new factory bolts.
