i have noticed recently that a small amount of an oil like substance is on the underside of my hood over the left side of the engine,i haven't seen any leaks anywhere and it doesn't seem right to only have oil on the hood and nowhere else.anybody else have this problem? my oil level hasn't gone down either,and neither have any other fluids

 

is it roughly at the belts? Could be your A/C compressor leaking oil.

 

no,it's toward the back of the engine,i think it's the oil filler tube,looks like it's been leaking,and my friend's tauras has a very leaky filler tube on it
