Hi Phil,
You are correct that the oil injectors contain a one way check valve, but you have the operation backwards. Air is allowed IN to the intake chamber, and under boost the valve closes preventing air & oil from blowing out. Check page D-17 of the FSM if you don't believe me.

My brand new oil injector allows air into the engine. (I bought it to replace a bad one that was clogged in both directions)
