Hello all, I need some help. I have a 2004 F350 srw 6.0L with 106000 miles. I recently purchased it and I love it, but I have a few issues with it. It does have head studs, new gaskets, EGR delete, FASS Fuel system, piller gauges, updated fuel pressure spring, complete 5" exhaust and usually runs very well. However I have an issue with one injector sticking from time to time. I have changed the oil in it four times since buying it in December. Just trying to clean it out, and that has helped a bunch, just not completely. I use Moble 5W-40 syn. oil and used ARCHOIL on the first change with some results, and have recently used REV X with this last change. I have noticed a little more help with it even. My question is this. Should I continue trying these products in hopes of resolving my sticktion issue, or just purchase a new injector? If I continue trying is it going to hurt the cylinder at all when the sticktion occures?
