[Tigers] "Carbonized" Bolt Head?

[michael king]

i thought you basically got the dirtiest oil you can find, heat it up and
then put the parts in it and leave for a while, then let it cool then
remove.

This is how you do the tools for the tool kit.. IIRC the dirtier the oil
the better, so find a friend who doesnt service their car often! :P
