[V8] [urq] Liquid penetrant test - 50/50 mix of ATF and Acetonebeats Kroil etc.

Your timing of that trick couldn't be better as I'm in the middle of a
job on my 74 vette ( summer car II ) I broke two bolts off at the head
!! ( trans cross Member ) Now I wonder if this will work upside down
from underneath the car ? I guess the capillary* action might work.

One question to the group ... Can you braze a standard exhaust system
with a propane touch ?
Thanks in advance superdave

 * capillary motion is the ability of a substance to draw another
substance into it.

One other one I read about is the 'Candle Trick.'

Got this from one of the droF forums:

"The easiest and slickest way to deal with rusted-in bolts, regardless
of where they are is as follows; 1. find a candle....yes, an ordinary
candle from the kitchen drawer 2. get a torch. acetylene or mapp work
best, but propane will do 3. heat the metal AROUND the offending bolt as
hot as is practical.
4. feed the candle into the threads untill the wax quits melting 5.
repeat 3&4 a couple of times 6. use an easy out or a pair of pliers (if
a stub is left...)

Quit cussing these situations and start acting like a hero because you
know this trick. most of the time, the bolts will come out with finger
effort! this uses the same principle as sweating copper fittings, and
will clean and lubricate the threads to the point that removal is too
easy."

Anyone tried it?
