Ok out of nowhere my engine started ticking. I think it is comming from the injectors. I have DSM 450cc injectors, we all know how shitty DSM's are. The ticking will come and go when it pleases. I have tried the screw driver to the ear trick to my valve cover and my fuel rail. It is silent on the valve cover. The fuel rail seems to be where the noise is generated. Besides being annoying as hell, will this cause any problems? Are the injectors faulty, need cleaned, or just plain loud? I never noticed it before the injectors were in my car. BTW it is in a B16 w/B16B pistons and cams, with quite a bit of mods.
