Can't figure it out, i have a small amount of oil on the bottom of the hood which i clean off each weekend when detailing the car. I just replaced the stock airbox with an SLP version and when i took of the assembly i noticed a good amount of oil on the bottem side of the air bellow connection where the air flows into the throttle body. anyone have ideas? I keep the engine bay clean so there is no other oil that i can see????

 

Are you sure you don't have a leak around the rotating assembly and it's shooting up into the engine bay? Start the car, put it on ramps/jack stands and check around for leaks. There's an oil leak, you just have to find it. What about the oil level? Has it been dropping?

 

Maybe power steerng cap seal?

 

found it power steering return line. dealership replaced, not cheep for that much labor.
