Rear turbo bolts won't come off!

[muhoo]

I'm trying to remove my turbo (to replace o-rings and also to R/R fuel pump).

Got every single bolt off just fine with PB Blaster, hammer, and patience, except, the two rear turbo pedestal bolts, and the bolts connecting the up-pipes to the adapter. They are stuck on there good. The bolt heads have already rusted down to 9.5mm, so a 10mm 12-point wrench is just rounding them off. I can slam a 3/8" 6=point onto them though.

But, no matter how much I pound them, or how much PB Blaster I put on, they're not coming off.

Should I just give up and attack it with an angle grinder? Is there any other way to get the #@(%& things off?

When all else fails use fire.

Give you an old trick my father in law showed me once when I could not get d/s bolts out of my race car. Get a tea candle and propane torch, heat up the bolts and melt the candle into the threads of the bolt/ nut. When the wax gets down inside they 'should' come lose.

mever had this problem before but leverage is always your best tool, if not an air hammer is savage but works due to the BPM

If u are talking bout the clamp that Holdo the up pipe to the the turbo i cut that with a dremmel

94-97 PSDs don't have the clamp they are 2 bolts and 2 studs. Lots of pb blaster and heat the get so stuck in there from heat from the exhaust its not even funny. As far as the up pipe clamps to y pipe bolts go you'll probly have to get new ones. Try using a 10mm 1/4" drive socket, swivel, and 4" extension for the pedestal bolts.
