Oil Leak Above Filter (not what you think)...
2006 WRX 5 spd.....
As the title says.
Here is what I have changed so far:
Oil cooler gasket (twice)
New oil cooler
Valve cover gasket (it was leaking also)
Just finished the valve cover gasket earlier today. Not really surprised that there is still a leak. The oil is puddling in the same old place above the oil filter.
So I decided to sit under my car while it was running. The oil is definitely coming from one of the two bolts directly above the oil cooler. Which is well above the oil cooler gasket.
Anyone have any experience with this? Any what is needed to fix it?

Maybe it could be a front main seal? Or the oil pump is slightly leaking from the bottom?

take a white paper towel, wipe clean the area, then take a fresh towel and repeat the experiemnt where you run the engine.
When the oil seeps again, wipe it with the white towel and look at the color of the oil.
This is probably hydraulic oil from the powersteering banjo bolt.

I have the same leak. I looked at a parts break down and found out there is another o-ring (same size) behind those bolts. I'm actually going to attempt to replace this tomorrow during my oil change. bad news is i'm pretty sure you need to remove some other stuff to get get to all the bolts..... hopefully I don't break anything in the process lol.

Let LED's light your way!
Note: see Vlad's advice above. To reiterate, the power-steering pump is effectively located over the oil-cooler. If it is leaking, the fluid will run-down the face of the engine to or near the oil-cooler. Thus his advice to check the color of the fluid is valid: if it is red, it is power-steering (Dexron or equivalent) fluid.

This is because the oil-cooler is angled away from the exhaust-header collector. The exhaust-header is different from other models and is designed to be slightly restrictive.
