Almost looks like it has been sucking on some unfiltered swamp water.


Hard to say with the low Q cell phone pics. Looks similar to oil and antifreeze burning however.

Was gonna say the same thing. Almost every set of ex. valves I've seen had hard white carbon(?) buildup. I found it WAY too tiring to try to grind it off, so I just got new ex. valves.

Steel bristled brush worked great for me...

i soaked mine in atf overnight, scraped it with a blade, brushed it with a wire brush, and still they had build up on them

one of those wire brushes for use in a drill (all the bristles sticking out one end, not around the edge) makes short work of it...

Clean them up and check for excessive wear on the face and stem.
