need to get the plug out that I need to put a new union in for new dipstick but its in there really tight.

I've had vice grips on it and its turned a bit. put a cut off screwdriver up inside it and hammered but doesn't want to budge. don't say heat because I've no way of doing it, apart from a lighter.

that's the new one.
thought about just drilling a hole up inside one already in there but then why would they supply a new one. the dipstick tube has to seal inside top.
