Default Bolt stuck on turbo

I'm having trouble with one of the bolt on the exhaust side of the turbo. It's one of bolts holding on the metal plates. I've tried soaking it in pb blaster over night and also throwing the turbo in the freezer then taking a torch to the exhaust side of the turbo. Nothing seems to get this bolt unstuck. What makes it worse is that only the open end if the wrench and it will slip off the bolt.

I'm close to thinking of cutting the head of the bolt of and drilling the rest of the bolt out.

What do ya'll think?

I just had this same problem. I had 2 studs stuck. I got one out by using the heat gun + fence pliers. I used a heat gun on it and tapped on it with a hammer then eventually took the pliers to it. It took about 30 minutes but finally came out. the second one i just snapped off and retapped. I gave up when the above method did not work. They were 8mm anyway so i just made them all 10mm.

no space for a socket. only enough space for the open end side of a wrench.

So I ended up just cutting the bolt off. Now to the task of removing the exhaust housing.

Bummer. Next time, use a jackhandle or broomstick to clock the housing slightly in relation to CHRA so you can get a box-end wrench on it.

Now, when you put it back together, anti-seize.

BUMPING this thread, because i had the exact same issue last night and now I'm looking to resolve it. Same exact bolt, i got the other 3 by using the box end of the wrench, but you cannot fit a box end on this bolt due to where it's at.

Do you mean to slightly clock the turbo even though the last bolt isn't loosened? Do you mind elaborating sav?

Anyone else have any other ideas, the open end of the wrench just flexes and cant provide the torque i need to loosen this thing, box end wont fit. Heat didn't work because the root problem is that the open end of a wrench sucks.

I just cut the head off the bolt. The rest of the bolt came out easily after that. You can easily get a new bolt at lowe's or home depot.

I had to do some impressive jacking with a bolt and nut on my turbo to get the CHRA out, I'd be surprised if you could rotate it without loosening that. I vote for bolt cutting.

Dang, this is what I had feared. Okay, I'm going to soak it more in PB blaster, try heat - maybe try the freezer method. If all else fails i'll resort to cutting.

Thanks, and if anyone else has suggestions please do chime in.

Soak soak soak in PB blaster. Try spraying some inside the exhaust housing to hit the other end as the bolts poke through.

I did it with an open end. Kind of hammered it onto the bolt head for a snug fit, braced the turbo on the ground in a way that it wouldn't move with downward force on the wrench, and wailed on the wrench/bolt combo many times with a rubber mallet plus my weight pushing down. I was about to give up when it broke loose lol.

No heat here, just a few days of spraying and smashing.
