Les,

The only thing unique about the front of my engine is the pair of
serpentine belts. No one I've talked to, including myself, thinks there's
any possibility of their causing axial loads on the crank. There were NO
signs of radial damage to the front bearing as I'd expect if there were a
problem. There's no reason the serpentine belts should cause more problem
than the V-belts. Also, with the excess end play, I can literally move the
crank fore and aft by hand, even with the belts in place.

As for oil starvation, that's unlikely: The #3 journal (where the thrust
is taken on the Cad) showed no different wear than any of the others --
just that minor amount caused by the circulating debris.

Today I talked to Marty at Maximum Torque Specialists. He thinks the
torque converter is the cause of my problems; he claims the housing CAN
expand enough to take up my 0.125" clearance. I'm still skeptical, but
with nothing else to blame, I'm going to replace the TC with the best one I
can find -- any suggestions? I'll also have the builder of this one tear
it down to see if they can find anything wrong with it.

After I drop the engine tomorrow, I'll be looking for any signs of
interference that I may have missed before. The general assumption, in the
transmission industry at least, seems to be that an expanded TC would
immediately cause massive damage to the transmission -- I saw NO signs of
any damage when I had the transmission partially disassembled to replace
the input bushing. Maybe the TH-425 is especially rugged in that area
because of the chain drive?

Ideas welcomed.
