As a forewarning, this is not a job for a novice. This is an interference engine: If you do not align the camshafts correctly, serious mechanical engine damage will result. Therefore, I have supplied you with this is a step by step guide explaining how to properly change the timing chain, guides, tensioners, and phasers on a 5.4L Triton 3 valve.
These 5.4L Triton 3 valve engines are known for their distinctive rattling noises. Some noise is normal but excessive noise warrants an inspection. On these engines the timing components are the likely source of the noise. The camshaft phasers, tensioners, and the guides can fail. Although there is no maintenance schedules set up on these for timing component replacement, I do recommend pro-active replacement.
