I have a b16a in my civic and we installed a skunk2 intake manifold and when putting the injectors back on there was no apparent need for the spacers that were on the fuel rail before. So we didnt reinstall them. but now i have a rattling noise coming from the injector/belt area and im not exactly sure if that is what happens regularly without the insulators off or what. so im just trying to find out if that is where the noise is most likely coming from. everything else was done right to my knowledge, so thats the only thing i think it could be i just wanted to see if that is what you guys thought as well.
thanks
