Hi guys, Iv got a stock lbz with 150,000 I just recently did head gaskets on. When getting on it hard I get an injector that sounds like it sticks open and knocks. I have replaced 3 injectors already and now have a 4th doing it. I am beginning to think the injectors are just coming loose instead of actually going bad and knocking? I did not replace the hold down bolts when I did the head gasket job but I torqued them down to spec. I have now ordered all new injector hold down bolts and seals and going to pull all of them and reseat. Any suggestions? Thanks
