So here I am with 10.7 hours on my brand new 9A with a hartzell CS prop, and I'm seeing a fine mist of grease showing up on my windscreen. At about hour 6, I had a rather large deposit show up which caused me to pull the spinner. I discovered that about a tablespoon of grease was deposited on the inside of the spinner directly opposite one of the grease zirks on the hub, which coincidentally no longer had the little plastic cover snapped closed. I snapped the cover back on cleaned up the spinner. Today on a lap around Austin, I again had another fine mist of grease show up on the windscreen. This time the inspection revealed a smaller amount of grease ( about a teaspoon ) on opposite sides of the spinner, again directly above two grease zirks which no longer had the caps snapped closed.

The grease zirk caps are token at best. They are made of very light weight plastic ( friction fit ), and could not possibly be permanent. What's going on here?
I understand that CS props that have been overhauled ( which this has ) can sometimes leak a small amount of grease, but this is too coincidental to be over greasing.... or is it?
Are these little plastic caps the only thing that keeps small amounts of grease from escaping? If so, why aren't they made of stronger stuff or at least have a better locking mechanizm.
Many thanks for any wisdom you can provide.
