Default Oil Leak near the filler neck /intake

Guys, I seem to have a pretty good oil leak coming from what looks like under the intake. I don't know how fast it fills cause I just found it while doing the Timing Belt. Anyone have Ideas where it may be coming from? Thanks for your advise in advance.








You can see the pool to the right of the number plate, However, I mopped some of it up with a towel.

Most likely from the oil fill neck gasket failing.

I had the same issue on my 81 and replaced the gasket along with adding a GB baffle and all has been well since.

On an S4 it is. They commonly warp which leads to people replacing it with a metal one from an 85-86.
