~Yesterday my uncle, who is longly retired, visited me. He used to work on
FIATs back in the 50's and 60's.
I described him my probelem, he immediately told me that I had a worn
bearing, and when I showed him the old one, he told me that this was
definetely the problem.
Next he asked me how my oilpump was. After I told him that I had also
ordered this one, I showed him the on that came of the car. He told me that
is was no luxury to replace it.
I am more into old Honda's, but I am happy that, with the lists help, I had
drawn the right conclusion and ordered the right parts.
Thanks all!

No wear at all.
