the good ol my dp is being a bitch to remove thread
 

im close to killing myself or taking a sledge hammer to my car .. anyways i unbolted my dp and 3 bits remained .. the top right .. bottom right and bottom left .. top right was being a bitch .. didnt want to come off (tried vise grip and wd40) .. so i had to go at it the hard way .. i sawed the fucker off .. and with that .. i had enough space to take the dp off .. now i have to extract the reamining piece of the top right bit .. it spins and starts to come out .. but then at a certain point it just stops coming out .. but it spins .. its as if the thread has become a parallel line rather than an angle .. so now i have a bit that only comes out to a certain point and if i continue to twist it .. it only spins but wont come out .. any ideas on how to extract the bit?

I must have gotten lucky with my DP install...I'm not a very skilled mechanic, but I just took the install really slow. I basically sprayed PB blaster on the studs every half hour for a couple hours while I was doing other stuff, and they came right out

smells like a turbo removal is on the way.....

You kind of screwed yourself on this one. Exercising a little more patience might've helped you avoid the situation you're in now, which isn't looking good. I'm amazed you were able to get a saw in there to hack it off.

Hate to say this, but you probably will have to remove the turbo assembly to remove the remaining exhaust stud (what I'm thinking you're referring to as a "bit"). It will have to be drilled out in order to be removed, and there's no way you'll be able to properly do that in the limited space available.

It pays to do some research before you tackle any job on the car, as many parts are hard to get access to, and it's easy to forget they're already 10+ years old already.

And take your time pulling the turbos. The turbo studs and nuts present the same challenges, except there are twice as many.

*sigh* ok gonna get back to working on it .. if i dont ever post on this site again .. that means i have killed myself in frustration

Be cool bud. I had similar problems but PB blaster can work wonders. If you can have at least three good hangers to screw the back onto you can get away with it (maybe a small exhaust leak though) but those things really get fused together with all that heat. If you do have to pull the turbos, take your time, be methodical about it, and replace all the screws and or bolts with new ones.

The best advice i can give you is:

1) calm down if you get real frustrated just walk away from it for a while and go back to it once you have cooled off.
2) get a small propane torch from Home Depot or Lowes and heat the area around where the stud is located (not the stud itself) and get it so its cherry red. Then with a pair of vise grips, channel locks twist the stud out.

Take your time and be careful it should come out.

Even better than PB Blaster is a penetrating oil the military and gun owners use called CLP or " Breakfree CLP". I used this when pulling the DP studs on my car 4 years ago as well as any other frozen fasteners and it has never failed me.

hehe .. i finally got it off .. basically twisted the stud with vise grips .. then hammered at it with an axe .. and twisted it another 180 degrees and pounded at again .. and continued till that bitch popped out .. never understimate the power of the axe >:]

yes that is the best advice .. usually that works for me too :) but most of the time im impatient .. i dunno why .. but when i do just say "fuck it" and had enough i walk away .. come on this forum .. play some games .. relax a bit .. then come back to tackle the problem .. and usually it solves it

I'm glad you got it out. I think the real fun is going to be when you try to put a new stud back in.

Absolutely go down to the store and get an M10x1.5mm tap and chase all those threads.

I wasted a lot of time recently messing with a gunked tap hole there.

put a new stud in .. had a problem .. but reversed it to the longer end .. no problem
