Nick,
I don't think 75% of broken
bolts need to be broken. Take
your time, take some CRC 556
or WD-40 and take a little
heat and work slowly with it.
spray the bolt area (head of
bolt, gasket between the head
& outlet pipe) whenever you
can for a day or two. wire
brush the area first so the
rust doe not soak up the CRC.
When you are ready to take
them out, heat the block a
little until the CRC starts to
cook, take the heat away and
spray it again. The hot block
will draw the CRC in a little.
Do this a few times and then
try the bolt. Turn it both
ways (lossen-tighten) until it
breaks loose (not BREAKS). Do
not try to turn it out fast.
Just a little pressure each
way. Keep the heat and spray
up too if it does not loosen
right away. When it starts,
spray it again keeping the CRC
flowing.
I have had a lot of luck with
this method. It takes patience
but that is better than
drilling and using an screw
extractor.
You may even try tapping the
area where the bolt is in the
head the break the rust so the
CRC can soak in.
When you reassemble DO NOT
FORGET to use "Never Seize" on
the threads.
By the way, are you coming to
WOTSRA in Macungie in August?
