Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

1999 Boxster 2.5L, Tiptronic, 120K miles, LN IMS, no codes present, no oil leaks, no loss of performance.
Sorry for the poor video quality and the noise I'm referring to is the consistent chirping noise that is coming from the passenger side. The last time I heard this noise it was a loose spark plug that had not been torqued by the mechanic. My current mechanic claims it is an exhaust valve that is not closing properly so I had an oil and filter change and Swepco put in to see if it is a hydraulic issue and it can be resolved. Oil used is Mobile 1 5-40 wt. as recommended by LN. The noise can be intermittent and some days is twice as loud as the video and some days I can't hear it until the car is warmed up. Not trying to second guess my current indy because he has been working on Porsches for a long time and is well known and popular with performance car owners in Monterey, just want to get a second opinion from someone who has had a similar noise.
Thanks!

Try this link, I just put it on "share" so hopefully it will work. Thanks for the heads up.

I would remove the accessory belt and spin the various components by hand. I suspect one of those components is making the noise possibly due to a bad bearing. Check the belt while you're at it too.
Sounds like a pulley bearing to me, too.
Spinning components without the belt on may not work because there will be no load on the bearing. A stethoscope may help you zero in on it while the car is running.
