might not hurt but use it sparingly.


On some of the ford trucks that used to use the real long plug from 05 to
08, the used to break off (looked a lot like the long one he had in the
video there) people would use a lot of spray penetrating oil, and it would
drip past the threads down into the cylinder, and upon first crank, the
engine would hydro lock. that would take a lot of penetrating oil, but some
folks were using it like crazy, due to those damn plugs breaking.

thank goodness Chrysler hasn't gone thru something like that, having to
invent a new tool just for extracting those plugs!
