Engine noise - Timing chain??

Hey all, I have a 2017 q60 premium with 67k kms on it.

My Infiniti mechanic was changing my spark plugs when he noiced a sound he thinks is the timing chain. He also said my turbos were on their way out (oil in intercooler). I went to infiniti and theyre going to do the warranty for turbos. I also showed the tech the video attached and he think it might be timing chain too.

Fucked part is, if that is the case, Infiniti quoted me 7 thousand dollars... (3 for labor 4 for parts) WHILE the engine is already dropped for the warranty work. Wont be doing that work regardless and will have to figure out a plan if it does need replacing.

Has anyone had experience with a timing chain or has heard this noise and knows what it is? Getting the work done next Wednesday but stressing in the meantime lol.

Noise starts around halfway through video around 12 second mark, you'll hear an on and off "grinding, vibrating noise?" Only happens on cold starts after car is sitting for a while like overnight.

Mods: not tuned, LDPs, CBE, catch can, heat exchanger, intakes. Have updated the serpatine belt already and run 5w30 oil.
