special tool to remove gasket on o2ensors?
the gasket? not the O2 sensor itself? if it's really stuck on there, why bother with it? but a set of steel chisels might help to create a non-sealing surface, so I wouldn't recommend that...PB penetrating cattle-ist has been known to cut thru too...Brake cleaner is not as messy...and will get you there~
a blast of one ....and then the next would do the job~
a screwdriver is your "special tool"~
