I am getting a ticking sound which is not a valve,we hot set all of them again to make sure,not an exhaust leak,but I can hear a mild ticking sound,worse when the hood is open.It's a fresh re build vertually stock with new headers and flowmaster exhaust to the back.I was wondering if a bad injector would tick like that.If it is an injector is it best to just replace them all.

 

Yes, but good injectors will tick too.

 

Will a bad one or even new ones like you say tick to the point were it almost sounds like a loose valve.I just want to make sure,I'm not having any power issues,but a couple people have mentioned they can hear the ticking.Maybe that's just the way it is???
