Re: Roto Caps don't turn
Someone has been into your engine before, at least once. No surprises found there.
Originally, Crosley used two long valve springs and no spacers or Roto Caps. Then they added Roto Caps under the exhaust springs, so they had a short spring on the exhaust and a long spring on the intake.
Later, they added a spacer on the intake and ran they same short spring, on both the exhaust and the intake.
Crosley never ran the Roto Caps on the intake valves.
So if you have some that appear to be stuck permanently, just run those on the intakes, but be SURE that the exhausts have good, functional Roto Caps on them.
