I agree with Daryl here.
Of the thousands or kids I've taught, I've seen SOME problems associated with removal of valves (valves dropped or bumped, caps cross threaded, trumpet valves in backwards, plastic guides sheared off), but I'll continue to teach kids to take the time to remove pistons for oiling. It seems lazy not to!
My students get a handout with diagrams showing them the 'safe' way to oil valves, and how to reinstall them. I give a lesson on this, and reinforce it often. Sure, I still get notes from parents saying "my child couldn't practice because their trumpet is broken" (valves replaced backwards), but the message usually sinks in.
Cheers,
Ian
