dip stick tube removal ?

I've ran into this issue several times in the past. I've tried a few different removal options, the only one I had very much success with was to carefully insert an EZ-Out aka screw extractor, lightly tap it with a hammer to get it seated and clamp a pair of vise grips on the hex end. spray the dipstick tube base with some penetrant and carefully twist the EZ-Out while pulling upwards with mild pulling force. It should wiggle it's broken *** right out. Just my thoughts on it, best of luck dude.
