Oil leak. Need ideas on the source

[VG33QX4]

I have an oil leak where the alternator bracket meets the motor. This is on a vg33 motor has 155,000 on it I did timing belt 20k ago and cam seals are good. This leak has been occurring for well over 75,000 miles is very minor but just aggravating as it leaks down the entire motor. This is on the passenger side and appears to be near the front exhaust manifold port. Where the oil pump housing meets the block. I know the leak is below the valve covers and above the upper alternator bracket. And it's not the valve covers. Any ideas let me know.

Just before your next oil change (when the oil is nice and dark and easy to see), clean up the engine room with a couple of cans of
Gunk and hose it all out. Let it dry completely.
Fire it up and run it at a fast idle (2K rpm) and see if any oil comes out. If it doesn't, drive it a little and check again.

Tried that before. I was unable to locate the source. The leak is minor an takes time to show itself. But over time it makes a real mess. Thanks. Any idea what's in that area that could be leaking?

Anybody ever notice how close the power steering braket is to the oil filter. I noticed yesterday for the first time. It's like 1/4 inch gap. Thought that was close

Found it. It's leaking at the oil pump

was going to say check your oil cooler... my 3.5 had that issue but has since been fixed.

After further investigation. The oil pump was leaking very very minor. The real culprit was the front corner of the valve cover that was leaking down the block.
