Yeah, that beats buying the OTC puller for $100. You're somewhat better off with something that fits tight into the grooves - but in my experience, when they're stuck - they're stuck. I've had the factory-made puller for 30 years, and I don't think it's ever saved me yet from a badly stuck injector. I think if someone made a puller that actually gave a steady pull on the injector, instead of a slide-hammer, it might work better. As far as using penetrating oil, it's never worked for me. When the little teflon carbon-stop seal burns off at the bottom of the injector, it really gets stuck. I just pulled a cylinder head for friend a few days ago to press out one stuck injector. Even with a 20 ton press, it came out hard. It is simply a bad design. I've ruined countless good injectors by trying to remove them. In my friends case, he was rebuilding is engine and found one injector that was stuck. It is almost a new injector, maybe one year old. But, he put it in dry - it should have been coated with Never-Seize. So, we had the head off anyway - and - had the choice of putting it back on with the stuck - but good injector, or ruining it, cleaning the carbon out of bore, and installing a new $100 injector. We did the latter, at least this way, if something goes wrong in the future, the head won't have to come off again (hopefully).
