As per the FSM "Factory Service Manual if you can blow air through from both ends of the oil injector nozzle you need to replace them. I have 8 of them and all of them except one can blow some quantity of air through.

Am I out of luck?

I have never heard of that, or am aware of anyone that things such an inspection is critical.

If you are paranoid you could probably find someone selling used ones for mega cheap on the for sale section.
