While in this vein, am I correct that the engine valves are self adjusting too?

Been searching around and I've not found anything.

603s have a timing CHAIN. No the timing isn't adjusted by itself, it's Mechanically Injected.

Yes, idle is called ELR from memory. Red deal on back of IP.

Valves are hydraulically actuated... simply follow the cam so they can't adjust themselves.
