I think this has been covered before with previous posts with a lot of different speculations about what the "tick" could be in the 3.5 motors. I have an annoying tick in my engine on cold start ups that gets louder when you rev the motor. From reading other posts I believe the rocker arms need to be replaced but there is no recall on these so far, at least not that I have seen. Everytime I take my car to the dealer for an oil change I remind them of it and they always tell me either they don't hear it, or its just normal. This irritates the crap out of me because I can hear it clearly!!! I don't know what else to really do other than maybe get a second opinion from another dodge dealer? This tick is loud at times but is not noticeable during warm or hot weather. Any input would be much appreciated....
