I have a 96 328 and there is a constant ticking noise that seems like it could be lifters but the ticking noise gets faster as the engine speed increases, you cant hear it when the hood is down but when working under the hood, its prominant and annoying. I wanna believe its the lifters but my car doesnt seem like it has as much power as it used to. The noise is coming from around the manifold by the head which causes me to believe it could be a faulty injector but the dealer wants like $100 a pop for each one and u know u cant just replace one. Has anyone had this problem and is it as serious as im making it or am i paranoid. I would appreciate the help.
