Shouty Kilmer. That guy!

I figured replacing PCV valves on a schedule was just a plot by Big PCV Valve!

Apparently as long as you can hear the check valve moving around freely when you shake it, it's good. (Or so said some page on the intarnet.) Before: no rattle. Post-multiple-carb-cleaner-sprays: free rattle. So I put it back in. I also cleaned all the plumbing & passages.

I should check to see if any more stuff barfed out of it since last weekend.
