Re: [DML] Exhaust stud removal

[Martin Gutkowski <webmaster@xxxx>]

Firstly, don't keep trying with the vice-grips, you can round off the 
stud too much. I don't know what they're called in the US, but I was 
able to buy a set of stud extracotrs from Halfords (kinda like your 
AutoZone, but does quality tools). They look like deep sockets but have 
a small hole in them, stated as either M6, M8, M10 or M12 and internally 
there are three knuled "fingers" which grip the stud as you turn. The M6 
one can be encouraged onto the M7 studs. There's a picture of us doing a 
new head and the stud extractor is sitting on the carpet.

I will be submitting an update to Dave Swingle on the exhaust manifold 
gasket article because I've now done a car where everything was rusted, 
seized and/or snapped!
