A/C pulley leak?

[Jackmove]

Noticed a leak on what I think is the AC pulley. Or maybe there’s a leak directly above it? Looking for help diagnosing.

Recently had the serpentine belt replaced. AC still works great. 2017 JKU sport stock. 3.6 v6

I think the ac condenser holds 4 oz. of oil. The leak is not the pulley. If your ac works and the compressor isn't making noise, then I'd say it's dripping from above.

Oil is dark and metallic. Doesn’t taste acidic. Not sure why only the back of the unit is wet.

Oil filter bell housing is dry. Back of the engine is bone dry. Might just clean with brake cleaner and see if it leaks again. Maybe the oil filter leaked on the previous service? I’ve only put 3k miles on the car so I haven’t changed it since I’ve owned it.

So I read about oil cooler issues. Is this leak consistent with that failure? It’s located under the intake manifold, so I have to pull it. Wanted to get another opinion before I put in a half dozen hours pulling it. Someone suggested an oil sending unit. Anyone know where that’s located? Thanks.
