Engine knocking when giving throttle in park

Thanks for the video, yep that noise is not good, I would put your hand on the HPFP to see if this is where the noise is coming from and if so remove the pump to check the camshaft lobe which are known to wear down which will cause the noise can cause low engine power. Can I ask if there are any codes? Why didn't ford replace the last cam phaser, that seems strange. I assume they replaced the timing chain and tensioners correct? Please let me know

it was warranty work so they just did 3 phasers and seals no chains guides or tensioners the noise isn't the HPFP I listened with a mechanics stethoscope the noise sounds like its on the bank 2 front of the valve cover could the metal be from the phasers what could cause that its all magnetic metal shavings thanks for your help
there were no codes for anything other than EVAP system fault

Yep, you sound correct, the problem will be in the timing chain or remaining camshaft phaser, did the dealer do the work? If so, back you go and tell them what happened, they do this kind of stuff all the time, jump over a dollar to save a dime.

the dealer did the work but I just bought the vehicle from a guy that said it needed a engine he had the work done and soon after the noise showed up so he took it back and they told him it needed a engine but after looking it over I think its timing related but ive never seen timing shed metal but it does sound like timing this is my first EcoBoost so I don't know what they are like thank you for the help

Yep, no problem, the first thing I would do is remove the timing chain cover for an inspection. Then upload a short video or images showing the timing chain assembly so I can see it and help you fix it together. First double check that the noise is being generated from the timing cover.

Is it a knock or tapping? I ask because I thought the same. Took the cover off and found the tensioner malfunctioning which lead to chain slack and that broke the guide and the chain was shaving down the inside of the cover.

Yep, great addition to the thread, this happens all the time.

it sounds like a knock what do you think from the video? I can pull the cover and check, tell me what you think from the video (here's the video again)

Hmm, It can be carbon build up on top of the piston, this is a common problem, how many miles are on it? It also sounds like one of the pistons is might be broken, rod bearing issue or a sized wrist pin. Can you tell if the noise is common from the bottom of the engine or top?

I'd say it sounds like the bearings in one of your pulleys are bad making it hard to hear anything else. However, it sounds like it may just be misfiring. They were having issues with plugs breaking off. After the truck is warm I'd check the plugs and feel for excessive heat on one or more of them.

I cannot tell if its bottom or top end noise but there is some aluminum glitter in the filter, truck has 133,000 miles and not a misfire and sorry about the belt chirps and has magnetic metal in vvt solenoids so no clue I will boroscope it and check pistons

Yep, good call, you can remove the serpentine belt and then start the engine to eliminate the front pulleys. Let me know what you find please.
