Anyone have any experience with this sound? Or know what it could be? Started happening today with my 2004 986S. This was the idle sound after taking a "cooling lap" post spirited 15 minute drive. It was warmed up before driving spiritedly. Sound more evident on driver side. Seems to go away with a little addition of gas. Has roughly 141k miles

Got a durametric? Check your cam deviations. Sounds like cam chain pads are shot.

Also, check your oil level lately?

 

I don't have a durametric. Yes, oil level is fine, Indy shop that did my ppi said deviation within spec. Blackstone oil Analysis said nothing about plastic.

 

Not this year !
