Do they appear to stick out of the shroud the same distance when the engine is running as they do when it's not?

I can see your point, when it's spinning it's pretty hard to estimate how far out those blades are.

...yeah, certainly adds to the confusion in trying to pinpoint a cause doesn't it...oh joy, sounds like fun times ahead....
