[DML] YES, MAPP gas WORKS GREAT to loosen rusted Delorean bolts?

[Woody <BePositive2000@xxxxxxxxx>]

Mike,

I first used MAPP gas because I did not have a torch handy; now, it's
my method of choice for freeing frozen bolts, particularly exhaust
manifold bolts.

I use a torch with a fine tip; one that's designed to take the higher
temps of MAPP (not a standard propane torch).  The fine tip avoids
surrounding damage due to friendly fire and directs the heat where it
is needed.  Mostly, I've used the MAPP gas & torch to loosten exhaust
manifold bolts.

FYI, 14 years after first using this method and a copper anti-sieze on
the replacement studs, all I needed to remove the nuts and studs was a
wrench.

Another aside: When removing frozen or broken steel bolts on the
crossover pipe and cat. converter,I've had success using an actelene
torch to heat, then hit the air to blow out the bold, leaving the
threads in the pipe. . . This is a little gutsey, but it works.  I've
used the same method to remove a broken bolt from a casting.  Still,
use at your own risk; you could damage the female part.

Woody
