> I need some expert advise with regard to the exhaust manifold studs of my

> For 10 days ago I broke the exhaust manifold flange of the left manifold...

> With the restult that the flange has broken..

> On the otherhand, I either don't like the idea of taking the head off.

> So maybe I should aim for the second stud to come out.

> Both studs are almost flushed with the head surface (slightly below

> Is there a safe way to get them out?

>
> If this doesn't work out, how do I remove those broken studs then?
> And where can I buy new studs for my engine?
>
> Ofcourse I can try to drill out the number two studs since I think I can
> access this one from the left front wheel area (with the left front wheel
> removed ofcourse).
>
> But what if I screw up and the studs doesn't come out, since these studs

> leakage.
> If I break a drill for e.g. while it is just through the center of the
> stud (if I am lucky..) and the broken part gets stuck, cooling fluid will
> escape then!!
>
> So should I go for the 4 studs fasting method first?

> Any words of whisdom??
