Ouch!

That's a nasty shame - I concur with Pat, the sand man is evil when it comes to components that can not be really flushed. I'm assuming that you did a complete tear down and re-assemble - if not, I'd also be concerned about the area around the bottom of the distributor as there's some "nooks and crannies" there that can hide the little beads.

Sorry to hear about your not-so-good experience. Those Crane retro's are real pricey to replace, but that's the only sure way to know you've got all those little glass beads as they're impossible to see.

Good Luck on this one Keith!
