I'm slightly iffy about taking the valve cover off with my nonexistent mechanical know-how (and bad car karma) hehe.
I just sprayed some of that stuff onto the carbon on my exhaust tip to experiment and see if the foam will just dry up into nothingness (fingers crossed)
SuperMazdaKart, i'm still keen on getting that engine cleaner into the RIGHT port and seeing that white smoke come out the back of my exhaust
