2018 F150 w/5.0L at ~150k miles.
Had a P0019 crop up a couple times now with associated rough idle/stumble/stall.
The truck has the signature click 'n clack from the engine but nothing too alarming. Decided the best course of action was to replace the VCT solenoids and inspect the valve train.
Here’s what I found-
Both VCT solenoids look fine and function. The screens on the exhaust solenoid are pristine clean. Replaced both anyway.
Cam lobes- not a big fan of the look but the surfaces are still smooth. Unloaded rockers have the expected amount of play. Even on the worst looking lobes. So doubt there are rocker bearing issues, which they are known for apparently.
Despite how they look, the lobe surface is smooth and no surface gouging detectable by feel. Lighting has a big effect on the visual image…
Will put it back together and see if I get any issues returning. But curious your thoughts on the cam lobes, especially if you are familiar with these 5 liter Fords.
