The seat dressing tool I have will completely close up the injector hole. No amount of air pressure or flow will do any good here. The grease on the cutter will help but I can't say it will pick up all the shaving. The tool desing is sound but it looks to me like its to be used when the heads are off the motor. Otherwise shaving will follow gravity. Maybe filling the nozzle hole into the precup chamber will keep any cast iron shavings from fallin in. Then add air pressure after the seat is cleaned up may work.

You could just use the adapter and shove a hose over it, you won't need too much pressure to blow things out. Would that be even more redneck?

Sounds like a job for a vacuum stick
