<VV> Broken Crank!

[David O'Neal]

The engine number is T0625RH and the crank is marked 8409.  According to the
Junkyard Primer this is a long stroke crank. Do all the 164 engines have
this crank?
 
I haven't gotten down to the bearings yet, but there were no loose bolts on
the converter, no abnormal looking wear on the parts, and no unusual
vibrations in the car before this happened.  I am not very experienced with
Corvair engines though and I may be missing something.
 
Good question about that last bearing - if the engine has been rebuilt and
the wrong one placed there then it could be the cause.  Will check that
next.
 
Thanks for the questions and input.
David O'Neal
