Strange gas leaking noise from engine

[MaYouYe]

Hey scientists, I'm hearing two unusual noises coming from my engine. I suspect one might be due to the cam phaser (according to my dealer), but I'm not sure about the other. It sounds like there might be gas leaking from a valve or something similar. Any ideas or suggestions would be really appreciated! Here’s a link to a video with the sound:

. Thanks in advance for any help!

100% NOT a cam phaser. Might be the direct injection system or EGR. Either way, every raptor I had sounded and sounds like that. Usually just after start up in the first few min but I also hear it but not as loud after driving.

Thank you! I can hear this gas leaking sound when idle, but I am not sure during driving. Do you think I need to take it to a dealer for a repair? (Need to put my car at dealer for six weeks)
