Is this an issue?
Have you done the PCV mod?
The OE PCV is almost always clogged, and pressure builds up and oil leaks out.
The mod is on a sticky, and ever D2 should have this done. It is a remarkable improvement.

Nope! just saw so I guess i’ll be doing this during the winter
The PCV mod doesn’t take very long to do. Do it before you do the valve covers. If I had a leak like the amount that I see in the photo, I wouldn’t worry about it very much. You can try snugging up the outboard valve cover bolts without taking anything apart. IIRC it’s a 5/16 12 point socket. You need some disassembly to get at the inboard bolts.
