2018 3.5 Cam Phaser Noise
Enable HLS to view with audio, or disable this notification
Have had the cold start rattle but it always went away. However, recently the clattering from the passenger side of the engine (between cover plate and passenger side of cylinder head) has increased and believe I just need to pull the trigger on a phaser upgrade, and timing kit.
I would use the latest gen phasers (intake and output, all 4). New Timing chain, rollers/guides/tubes, etc.
I used a long screwdriver to isolate location of the sound to the passenger front phaser, it’s difficult to tell besides “top end”, but anyone who has a different opinion on cause please watch, listen and weight in.
