I'm not sure what this is

Take a rag and simple green that area, dry it, start the car and take a look. Quick look says feed line, but gravity doesn't agree.

Use a good thread sealant and tighten that feed line again. I hate teflon tape to death. ![vash](https://www.miataturbo.net/images/smilies/vash.gif)

I used some type of Permatex stuff on my dual feed fuel rail. The tape kept leaking, so after a couple times I used the sealant, and 10 minutes later no leaks.
EDIT: On second thought, the feed line looks dry. From the looks of the photo its whatever is above the feed line (knock sensor really?) that is leaking.

If you have a hose clamp over a braided stainless line, there's your leak. And you won't be able to fix it either. Not using a hose clamp. It will always leak without the proper compression fittings that hold the hose against the fittings.

Teflon isn't a sealant. If you are assembling two tapered fittings, it's common to use teflon tape. This lubricates the threads and allows the fittings to get much tighter than they would without the teflon. As the tapered parts are tightened, the threads slightly deform as the two tapers meet, and they crush seal.
So I assume teflon is used only for tapered threads? You learn something new everyday here....sometimes more.

Well, the echo what Pat has already said... I also think its the knock sensor. From what little I know about knock sensors, some or most (or all, I dont know) are filled with fluid. Looking at the pictures it looks like the end of the knock sensor is beat to ****, or has a crack in it, and is leaking its contents. So as already said, I think your wasting you time looking for an oil leak. If it were an oil leak, why would it have **** its load all at once, in that one place and then quit. If it were leaking around the fitting, it would be leaking all down the block by now. Makes no sense.

That's the same knock sensor that DSM's use. That is some sort of sealant that they cover the end with. Originally it feels like a soft epoxy, but later it degrades into sticky goo. They all do that eventually but it doesn't seem to bother them and they still work fine. If it's the sealant then it will feel like some kind of slimy adhesive or tar if you try to wipe it off.
