So I just changed all fluids, plugs, and filters on my newly purchased 2012 with 93k. I just wanted to do as much preventative maintenance as possible. The carfax was very vague about the maintenance history. So after researching other potential issues that are common with the 5.4, im wondering if I should replace the cam phasers and timing chain guide/ tensioners. After reading through various forums and Youtube videos, there seems to be a lot of contradictory info about if and when Ford fixed all of the timing/ phaser issues. Do you guys think replacing them now would be preventative maintenance or would I be fixing something that isnt broken?
