I have taken a look at my shop manuals and Tyler's book. While they supply
the correct tolerances, I lack the measuring equipment and experience in
using it. I would questions my abilities to decide if my pistons and
cylinders are out of round. As for the crank the best I could do is
see if it has any scoring. I would need the help of a competent machine
shop. Re-assmebly should be easier, along with checking all of the
tolerances if I have a good set of measuring tools. At least everything
is supposed to be correct at that point. Also I have no clue on how
to handle the cam and decide if it is worn or reusable. While I don't
doubt it can be done with little experience if you are careful, it is much
better to help on several jobs, before attempting my own rebuild. If
I choose a rebuilt (leaning towards a rebuild but still waffling), I will
attempt to do some of the stuff myself, but I will defer to a good
shop when in doubt.
