Bolt bustin' fun.

Two months ago I swapped my cracked 1g exhaust manifold for a 2g. In the process, I managed to break off 3 turbo bolts. Luckily, a friend of a friend who happens to have his own CNC machine saved my ass and removed the stuck bolts (after trashing a big endmill and like 4 carbide bits.) As luck may have it, the gasket between the exhaust manifold and trubo started leaking. Since I had just replaced the bolts in the turbo, I figured it would be no big deal to swap that gasket out. I was wrong. I tried once again to remove the bolts, and even after a couple days of spraying with liquid wrench etc... still managed to break one off. I life the other three alone after breaking the first.

The problem now is what to do to get this fixed.

I'm curious if any of you know what it might cost to machine those bolts out (again) or if that's even possible. Last time it was done, the holes were drilled out and plugs were put in and re-tapped to the correct size. (i'm guessing that this is what screwed me.

Relating to that, might it just be more cost effective to buy a used 14b and O2 sensor housing?

If I had the cash, I would just buy a new turbo.


Thanks,

Nope that was not the problem. You have to loosen each bolt like one turn at a time start by breaking one free then go across from it and break the other one loose. Just do this everytime and you won't have any problems. it's not stripped they just get binded up when you don't do them all together. I broke two of them off before and had a machine shop take one out it cost $65. I have not broken one since.
