As I want to make a quick release turbo on my cossie 4x4 I have to remove 1 of the 4 studs on the exhaust manifold.

How are these studs put in the manifold? Do I have to cut it off with a grinder and than put some new thread in it to use a bolt? Or can I loosen them after soaking them in WD40?

 

Fixed!

 

give us a clue then! It may be useful for others who have to do this.

 

you're right.

It's just a stud like the ones on the turbo so you can remove them. Maybe with a bit of WD40 and then they'll come out. Very easy job.
