I see that it's a really old post;
I have the pretty much same issue on mine, I didn't want to open another thread and I was wondering it this issue was fixed.
I have the same knocking noise as the video but not at idle. only when I apply load on the engine at 1500 rpm.
I use motorcraft oil 5/20
I supposed too it was a knocking rod but when I had this noise, the engine starts to have rough idle and I receive the code error p0345 (camshaft sensor circuit)
the alternator has been changed recently and the noise is not the alternator however
I'm going to open the valve cover to see the status of the lifters and the phaser cam.
do you have any suggestions on that? did you ever do this kind of repair? do you know if there are adjustable lifters or they are hydraulic? (I never opened a Mustang engine before, sorry
thank you in advance guys
