[QUOTE="d.p, post: 1868610, member: 16901"] Alright so Ford tells me all 3 of these have been done: 21B10 21N03 21N08 09/2021: PCM reprogrammed (mileage unknown). 01/2022: CAM phasers replaced (28k) 5/2022: exhaust cam phasers failed and timing chain tensioner broke or fell apart (30k). 01/2024: knock at idle after warmed up (41k) So everything has been done to this truck yet I still have that knock so I assume the issue persists or it wasn’t fixed right in the first place? Hence the failing on the exhaust side? I got an appointment at their Ford dealership on Monday so will see what if anything Ford or the dealership is going to do about it. [/QUOTE]
