just a update to installing a catch can about 10k miles ago.
It seems to help with quieting the valve ticking at startup, and i've probably collected a ounce or two of sludge.
I use to hear the ticking in the cabin at startup on some days, I don't hear it anymore.
The ticking is probably still there if i pop the hood, and stick my head in the engine bay but I'm to lazy to do that.
Not sure if it does anything else, but i'm still happy with my purchase.
