Looking for help regarding injector seal replacement. I have a set of LT4 injectors I bought used low miles, and a seal replacement kit from rock auto for them. I also bought the seal tool from Amazon. I can't for the life of me get the shaper tool to slide over the seals properly. Not a single one. I know I have the correct tool and the correct seal for these injectors. I have watched virtually every how-to video on the net, some of which are just stupid. Like this guy on the 'vette forum "how to replace injector seals with no special tool" takes his punch tool and stretches the seal and then slide it on to the injector. Then the video ends. Yeah, let us know how that worked out for ya when you go to jam that shit into your heads.

My frustration level with this is at a 10/10 and I've done everything I can think of to get this tool to pass over this seal without mangling it. The seal slide back against the injector as the tool starts to taper in size, and then the seal pops up over the lip of the seat and it's game over. Try again. I can't get the seal to stay put. It just wants to get sheered off the injector. My next train of thought is to try applying a heat gun to the seal a little bit, the idea of making it softer and more pliable is all I can think of. I haven't damaged any seals yet, still working with the original 2.

In the videos I've watched these guys just push the tool over the seal like it's no big deal and they do a set of injectors in a few minutes. I set 1 seal and I've got at least 3 hours into this.
