Re: [DML] Re: Broken Exhaust Manifold Stud NIGHTMARE! Please Help ...

[Woody <BePositive2000@xxxxxxxxx>]

I have mentioned this before and must emphasize, IT IS NOT FOR THE
FAINT HEARTED.

Prior to doing this on my D, I had done this several times on cast
engine heads with 100% success, so decided to try it on my D's Al
block.

I heated the stud slightly past red-hot to melting hot with a torch and
hit the air.  Out came the most of the stud.  I then used a tap to
finish cleaning the hole and inserted a stud.  Also used anti-seize and
found, 15 years later that this made a big difference in remove the
stud (the nut was rusted but the stud came out easily).

I had an extra head so I was willing to take the risk of damaging the
head, but might not have been willing to take the risk if I did not
have a spare to trash, so please take this into consideration.

Woody

p.s.  I have since had 100% using Mape gas to head the studs/nuts prior
to removal where anti-seize was not previously applied.
