Sorry about the poor photo quality, it was hard to squeeze under the car when it wasn't jacked...
I've got a small oil leak! I think it is only leaking when the engine is under load as there is no evidence of oil on my driveway (I'm currently running with no undertray).
The oily area seems to be a cover of some sort, the bottom bolt is missing and I can move it slightly with my finger.
Anyway... what is it covering? And how do I remove it to look for a leak, it looks a bit tight in there! Strange how it isn't dropping oil on my drive, though I'm not complaining lol
