I need help.
I broke all 3 studs off my manifold so had to drill out the bolt and
rethread with a tap.
When drilling out the broken bolt, I missed the center and also
drilled at the wrong angle.
Any hints at making a perfectly aligned hole right thru the center of
the bolt at the perfect angle?
I soak the bolts well with liquid wrench, maybe overnight. Some light
tapping will help the liquid penetrate around the threads.
As the drilling, I use a small bit to drill the center and gradually
move up in size until I can get an extractor tool in tight. Then
slowly remove the bolt.
Not a good idea to drill the entire bolt out in one try. Start small
with the bits.
