I would steer clear of anything with a motor built before June 2020. I believe this is the date Ford is claiming the cam phaser issue was resolved. I haven’t confirmed it yet, (still doing some digging) but evidently, they redesigned the camshaft bearing cap at the front—from a three bolt cap, to a four bolt cap. Their theory (based on extensive postmortem analyses of several “failed VCT engines”) was that the three bolt cap was not consistently sealing well and causing oil pressure/flow to be diverted which was robbing the downstream component of oil flow/pressure. The downstream component from that bearing cap is the VCT. (Cam phasers)
In order to make things “right” for the rest of us poor suckers, Ford would need to replace our heads. so yeah, that’s why this information is not readily available, and why Ford’s “fix”, for us, is merely a gimmick (PCM reprogramming
) to hide the larger issue until your vehicle is not covered by any warranty.
