Where is this oil coming from!?!?!?!
 

I am sick and tired of chasing this substantial oil leak. It is to the point I have to add oil like every two weeks because it has reached the bottom of the dipstick "safe zone". and I'm tired of dripping oil in peoples driveways. The underside of the car is COVERED.

If I didn't know the knock sensor was a blind hole, I would say it is leaking from there. This isn't my picture below, but the motor looked very similar. I couldn't get a good enough angle to get a picture of it. The second picture IS of my car. My only thought is the oil pressure sender assembly, but I don't understand how the oil would be getting up to the knock sensor.

Any ideas?

looks like the fitting for your oil feed / oil sender...

Valve cover gasket is the only thing I can think of. Can you look down between the intake manifold and valve cover to see if it's wet there?

I can double check this when I get home. Last time I'd quickly checked the valve cover gasket I didn't see anything there though.

As far as the oil pressure sender/turbo feed assembly, that was my first thought and still seems like a logical source. I just don't understand how I'm getting oil vertically above it.

Wind patterns in the engine bay are complex and can blow oil into strange locations.

Head gasket.

Shut your mouth. I refuse to accept the possibility. I've had enough HG scares with this new motor lol.
