Looks good so far, but I have one question, I need to replace my o-rings, and I had a spare SOHC laying around, and I decided to practice with that one so if I screw up its not a problem, but I still couldn't get the injectors out, but I had someone come and help me get them out, and while I was looking at the injector, I couldn't figure out how to get the o-ring off, nor was I able to figure out how to get an o-ring back on... I know this is probably simple, but hey, I only learn from my mistakes, I'll probably go back out tomorrow and try and figure it out, but any help would be appreciated, seeing as how you just did this... Thanks and keep up the good work
