Hi all,

I'm getting my first experience with bolts and studs on my 2.1 block and
have a question.  I have found 2 bolts already that came out VERY hard.
When I looked at them, it appears that some of the block came out with
the bolts.  The threads of the bolts have aluminum stuck in the
threads.  Is this normal, or did someone over-torque them or ???  These
were the steel bolts holding the A/C mount to the block.  Is there
something I should use on re-assembly that will prevent this?  What's
the best way to get these things out without shearing them off?

Also, how do you keep dirt out of all the ports and what not when taking
things off?  I had to take my air intake pipes off to access the bolts.
I used tape to seal the holes while I was working.  Is there a better
way?

Thanks from a first-timer.
