I dunno There is a degree of internal friction in engines, What about the valves? That would be a metal on metal wear surface would it not? ie the back of the valves as the spring pulls them back agaisnt the head. (pretty minimal wear i suppose) Did i just sneak one past old corolla's the walking encyclopedia, or really have a genuine argument that can't be corrected :_) oh sorry, i was working there is friction from the oil film of course. valves are a metal on metal surface, however they are not sliding, the valve is gently(ish) let down onto the seat, and so i can't imagine they generate any friction losses as such, or result in any wear from friction. i think the closest thing to metla on metal wear is going to be the piston rings at startup, and timing chains basically, metal on metal wear will not last long.. likely to result in galling = bad [Report message to a moderator]
