Seem to have a slight oil leak coming from somewhere. Only started to occur recently, seems to be less when the car is pointing nose down on an Incline rather then up. Can't see anything around the vanos, ccv, or engine seals. Guessing I didn't tighten the sump plug tight enough when I changed the oil last time. Decided to wash the underneath and see if it persists. It hasn't really affected engine oil level.
I had something similar lest year. Sump plug kept working it's way loose and a bit of oil was leaking onto the undertray. Park it on something not flat (like my Dad's drive) and it made a mess as the pool made a bid for freedom.
Ended up getting it helicoiled, now it's fine.

I wasn't expecting that or the multiple cuts in the front passenger tyre sidewall from whatever was sticking out of the hedge as I squeezed by
