Re: [DML] Re: Broken bolt

[id <ionicdesign@xxxx>]

To all that helped me with my broken bolts i have removed them with no problem. I soaked
them with dura-lube spray for 3 days, then drilled a hole in them and used a easy out
and they came out with no effort at all like they were loose to begin with.

Here is a good tip... use a magnet to pick up all of the drill shavings before you use
your hands to pick up the debris in the valleys under the intake, this will keep you
from getting metal slivers (dont ask how i know this).

I would have never removed the water pipe under the intake manifold but both sides of
the pipe were leaking other wise i would have left it alone. So leave the pipe under the
manifold alone if its not leaking and if it is leaking hope you dont break the bolts or
if you do hope they come out as easy as mine did.

Funny thing is that all of the water pump bolts came out easy with no problems.

Thank you to everyone that helped me.
