My 04" Ford F150 has a soft ticking noise. It has a V8 5.4lt. I have taken it to 4 different Ford Dealerships to ask why my truck ticks...it started at 107000miles and they all said its normal. I don't believe that...they say its bc of large injectors. I have Googled different reasons like oil pressure problems, injectors or spark plugs. All i know is, it only does it when the engines warmed up and only at idle. At 124000miles my truck died when i was driving it. I took it in at ford dealership 30miles away. They put a new Cam Phaser in on the driver side " but the ticking comes from the passenger side,HMMM??" changed the VCT sensor and spent 5 days working on the timing chain. Oh, they also said they had to update the software....what software??....It still ticks!?!
