Hi all, I check my oil levels quite frequently and it has always been fine if not better since a full oil change done a month and half ago.

Since then I have not topped up the oil at all.

Today I looked under the car and noticed 2 drop of oil on the drive which has happened over the last 48hrs. I have not hit any bumps or anything to my knowledge, not lowered etc.

There is an a4 sized collection of dry oil / damp patch if you can imagine it on the underside of the engine where all the plastic covers are, there is then a drop of oil about to fall in the centre...

I have just cleaned it all up with some tissue see how long it takes for more to build up, but what could be the case of this? Should I be concerned as I have a 200 mile drive coming up on Monday...

As I said, oil levels are perfect though. 

Could just be oil that was spilt during your oil change mate...sitting on the under tray and leaking slowly. Keep eyes on your levels. But should be ok I think.

gearbox?

oil return pipe from turbo or warped rocker cover leaking dwn the back

Either way, get the undertray off and have a look. Be much easier to see then!!

Under tray off, leaking from sump plug. New sump plug fitted by garage that did original service and so far its all ok. Rocker gasket also needs replacing in near future.
