So I have a 07 Subaru Impreza wagon 2.5. It’s seems to have oil on top of engine behind power steering pump. It’s definitely oil and not tranny fluid. I checked oil pressure switch and it’s not coming from that.

Does anyone have any suggestions on where it might be coming from? All help greatly appreciated. Thank you.

  • Did you check the Pressure sensor.

Here's what you do:

Purchase a 395 black light like this one on Amazon. Shine it all over the engine and see what it looks like, noting what is reflective and what is not.

Purchase some automotive dye and pour it into your crankcase through the oil fill neck. Drive the car normally for a few days.

Check the engine again with the black light. You should see a little fresh oil with the dye coming from the location of your leak. If not, keep checking every few days of driving.
