Re: Coolant Y- pipe problem

["Jim Reeve" <ultra@xxxx>]

Well, I've had some experience with this. First off, DO NOT try to 
pull it out with a screw extractor. I had a head break off of one of 
my y-pipe bolts this spring. I knew it wasn't seiezed in the engine 
block, (it was siezed on the y-pipe) so I yanked the y-pipe off and 
proceeded to drill into the bolt. I then put a screw extractor in 
there thinking it would simply screw out with this, I was dead 
wrong. The remains of the bolt didn't want to turn this time, and 
broke the screw extractor inside of it. Since this was made of 
HARDENDED steel, it took me TWO MONTHS to eventually drill, grind, 
swear, whatnot all the way through it. Once I finally got it out, I 
just decided to re-tap the hole with the next larger thread size. I 
was in a rush though. You may want to try a heli-coil or a thread 
restorer kit (never used either one though). In any case, you are 
going to need to drill out the bolts in the engine block. Good luck.
