Re: [t3] missing cooling tin


Back in the 60's and 70's, when the ad in the paper said, "rebuilt engine"
it meant that this engine was soon going to fail.  I developed the viewpoint
and passed it along to as many friends as possible that a "rebuilt engine"
meant that it had to come out and be thoroughly inspected.  If the guy had
done it himself and had all the receipts, and there was no bill from Rimco
for case work, I figured it to be a 10k-20k mile engine.  I once took a new
rebuild all apart and shipped the cases and crank, rods, cam off to Rimco,
then put it back together again..  It was a great engine.  If the rebuild
was by a shop, it still didn't mean anything if they didn't align bore the
cases.

The guys at Rimco explained to me that a case has to be line bored, cause
the bearings are no longer lined up after 100k miles, and they're worn, so
it doesn't matter.  New reground crank with tight bearing, mean constant
flex of the case and crank, and low miles til next rebuild.  Once I started
sending every engine off to Rimco for case, crank, rods, and cam, my engines
were as good as factory rebuilt.

In my opinion any rebuild should include Rimco blueprinting the cases.  You
would be amazed at how much things are out of line in a used case.  They
also say a used case is much better than a new one, as it has settled, and
once bored will pretty much stay straight after that.  My rule was that I
would assemble the case with crank and cam and if I couldn't easily spin the
crank with my fingers just on either end of the crank, there was something
wrong.  Everything in that case needs to be true and parallel, including cam
and cyl bases.

2 cents please.
