I have a 2010 ford f150 platinum with a 5.4l v8 and have noticed a ticking sound coming from the engine. I only hear this when engine is at operating temperatures and at idle. I'm going to take it to the dealership I bought it since a got it with a 2 year warranty this Monday. So far from what I've been reading its looking like its the cam phasers but i don't want the dealership to tell me its nothing and i don't have nothing to worry about. Anyone has this issue
