Hi all,
I have pulled and disassembled my engine in the '71B. This process being
a first for me, I have several questions.
How do I tell if my engine has been bored before? From my measurements,
the bore is about 3.16, which I believe is factory spec. However,
pistons 1 and 3 are different from 2 and 4. They look newer and less
worn also. Seems like I read where the pistons should be stamped with
the oversize number. Is that right? All I see is AE 17525 on the newer
ones. Does this mean anything to anyone?
The big end of the #1 rod shows quite a bit of wear (grooved about 1/32
inch deep) on the side of it. Is this significant? I was thinking of
replacing the rods anyway. Any opinions? While on the rod subject: These
are the kind that use no nuts. My Vikki Brit catalog shows them as being
used only on earlier engines until '67. My engine number places it as
manufactured in '70. Which rods should I use?
Now for the big question My local NAPA has a machine shop. I called
them today and they said they would be happy to do the machine work
although they are not too familiar with the B engine. They said that
they would be unable to do the cam bearings if they were the
"semi-finished type". They said they did not have the means to bore the
bearings in place. Can someone tell me if that will be necessary on the
B?
The shop guy also advised against magnafluxing the engine block unless I
already suspected it was cracked. What do you think?
I greatly appreciate the opportunity to present these worries to such a
knowledgeable panel. I thank you for your patience with my ignorance.
Regards,
Mark in MS
