1 of the bolts on my turbo/downpipe is seized up really bad, and WD40, heating up with a blow torch seems to work.

A mechanic at my local garage has suggested using a chizel or a nut splitter, and get the nut off, and clean out the thread, and refit a new bolt. Is that safe to do so? If not, what other ooptions do I have? I really want to get the decat on ASAP, so any help would be greatly appreciated.

Keigo - I had to hacksaw & chisel off one of my d/p nuts when I was removing my engine. Safe to do as long as you're careful not to damage any of the surrounding items.

Once you get it off, replace the stud as well as the nut

Keigo

Caz - Do I have to cut the stud off? How do you go about replacing the stud?

The stud should come off using a set of stilson's.

I'm at the advantage cause my turbo has been completely removed so working on it isn't an issue. In situ that may be a little awkward.

The studs can also strip their threads in the turbo...Mine did

Dremel with grinding discs did mine.

Raymond - What did you do after the thread came out? Did you run a tap through or something? What size was it?

Gizmo - can you explain further what you did with the dremel? It does loads of stuff, that thing! Can you run me through what you did?

I've finally got the exhaust gasket that's been on order for 2 weeks! Thinking of having a go at it in the next weekend or the one after. Thanks

Fortunately for me it was one of the bolts and not the stud which went.
Just ground the nut off with the Dremel grinding disk.
Now if its a stud seized in then thats a different story.

Using the dremal cut into either side of the nut and then using a hammer and chisel knock nut off stud , then using a dia clean stud thread up .I had the same problem with two of the nuts on studs it takes time but does work .

good luck

Ahem I bodged mine temporarily by using a nut and bolt through the stripped stud hole until I can take the turbo off to drill and retap the thread. That said, it's working fine and I suppose it should because studs are just for convenience anyway. Why don't we use brass nuts so that if the worst comes to the worst the nut will strip and the stud will be OK? Must be some reason why not I suppose - unable to take enough torque maybe?
