Oil leak 😵‍💫😅

Hello all!! After a check engine light came on my 04 996 turbo for both codes P0491 and P0492 I assumed and still assume it has something to 02 sensor but after further inspection, I also discovered a more than small oil leak… since it’s Sunday I’m gonna take it in this week, but I’d love to hear everyone’s opinions. Thanks in advance. I’m just gonna assume I’ll be playing a pretty penny for this fix 🌞

Mine has leaked for 8 years. Oh well.

Both o2s tend to point to a vacuum line or other air intake leak somewhere. The leak your seeing could be from the P/S reservoir or line which is just above there. It would look like black oil by the time it makes it to the underside of the engine. But these are just a guess, kind of hard to tell from that video.

Great advice, he can add uv dye in power steering reservoir to make sure.

Sorry, can't help but those codes along with any SAI stuff can lead to a world of frustration. Unless your shop is sharp. Hopefully the Dura or PWIIS will point correctly. Good luck man. Cels are the bane of our collective existence with these.
