Re: [Amc-list] HEI's chewing gears, how to avoid?

If the oil pump shaft hole is worn enough to give .003" run out it will destroy a gear in 15 min.
   There are MANY reasons this could have happened.

That's probably not a bad idea!

I bet you could get the dist gear oil-free, paint the flats
with red paint, let it dry over night, then run the car for an
hour or a day, yank it and see. Hard to believe it will ruin
the cam gear that quickly.
