I know the engine ticked b4...it always had a slight tick, but now when i pull into my garage I can hear the tickin. Then when i pop the hood its almost unbearable. Its only been a week, i dont see how the valves would need adjusting already. The noise seems to come from the back of the motor towards the injectors, actually right around the injectors, which leads me to think its them. Do these tick becuase of added fuel pressure of the haltech system? Anyone please....the car runs fine, but this is worrying me.
