Ticking/Rattle Under Intake Manifold

[mattr135i]

I know this has been discussed over the years & I honestly still have no clue on distinguishing which cause it could be, I might try my tackling the Vapor Purge Valve first & fingers crossed that fixes the problem. Engine cold, I can hear a small ticking/rattle sometimes & for the first time today, when the car was warm. I don't believe RPMs affect it but I could just be deaf (n54 has too many other noises ahaha) I have a video and hopefully it'll be easy to distinguish.[IMG]https://youtube.com/shorts/7S1fUbmUmKM?feature=share[/IMG] https://youtube.com/shorts/7S1fUbmUmKM?feature=share

Another thing to check is all the pulleys. See if any are loose. I had a similar noise which sounded like it was coming from under intake manifold and it turned out to be that 2 of crank bolts had backed out almost all the way and was causing the pulley to wobble a bit

I redid the tensioner and all idler pulleys when I first got the car a few months back & torqued everything to spec but, will definitely take that into consideration and double check!
