Ok to use compressed air on fuel injectors?

[96SVTpilot]

Greetings. I am planning on cleaning my injectors while I am in the process of a head and intake swap. Is there any problem with using compressed air on the injectors? I don't think there's any internal seals that can be damaged but just want to check and make sure. TY

I wouldn't reccomend it but someone might have done it before

I have done it, and as long as your air supply to the injectors is clean, it is OK. The key thing to rememger is that if you apply 12 volts to the injector, don't do it for more than a split second. The electromagnet coils inside the injector are only designed to be pulsed for short periods of time and never to be continously on for more than a few tenths of a second.

Thanks for the input. Your write ups are really helping me now during the head and intake swap. What would be the purpose of giving them juice during the cleaning process? I assume for testing reasons, but I have no idea how that would work. I was just planning on giving them a good bath, blowing them out, and changing the o-rings and caps. Should I be doing something else? When I pulled the heads none of the pistons looked like they have been running lean, so I ASSume the injectors are doing ok.

Applying power lets the air flow through them and blow out any liquid inside. The tolerances are so close that it is doubtful that any dirt trapped inside would blow out the tip.

Voltage allows the needle to open and thus you to blow through them.
