Only cold start. After 5 min or so, it goes away or be more quieter

Chain slack 100%
Coming from left belt side tho, so I guess not timing chain. Possible oil chain slack?

Gotta be the pump tensioner yes

Ok! Thanks. Here’s question- pump chain tensioner is small plastic piece with spring. So they are not hydraulic tensioner. Why do they go quiet when engine is warm? I don’t hear anything when it is warm

it's a metal spring
So technically they are working when hot but not in cold

technically yes but not optimally - it will get worse by time i'd get it replaced asap cause i wouldnt wanna wait 5 minutes every time i start up the car to even drive it
because if you rev it up it will damage your engine

Sorry to interrupt again but today was very warm, cold start around 26c. Still sounds like chain? It is passenger side wheel, so belt side.

Hey! I got the results after pulling oil pan. it was not pump chain since tensioner looks great and chain was not wobbling, pump was working too. now it is mystery again. hahaha
