Oil cap leak

So I've isolated my small oil leak to only coming from the cap, which I guess is a good thing, but I can't seem to solve it.

I've tried reversing the gasket on the cap...cleaning it and putting back on. That didn't work, so I tried to take the same cap and gasket and grease it with clean oil. Also didn't work.

Now I ordered the updated cap as my original was the older version. Tried the same methods as above...installed dry and new...still leaks. Then greased the gasket and reinstalled...still leaks.

Is this just something you guys are living with or is there something else I can try? In all my searching, these things seemed to work for others.

Any help/suggestions greatly appreciated!
