Just what I didnt need on a Bh weekend

[MADNESS]

Just about to go out for the weekend in my lovely freshly serviced cerbera and I find a puddle of oil under it !
The oil appeared to of come from the drivers side front wheel area, I took the air box off and had a good look around, cleaned it all up and run the car. No oil leak apparent though.
What side is the oil filter, thinking maybe the seal is not seated correctly.

Thanks for the reply, I'll take the wheel off and have a look around again tomorrow.
It is indeed a Ajp engine.

I checked the oil level to find it about half full, looking under the car it has a skid plate covering the engine, this has oil dripping off it. I took off the drivers side air box and cleaned the area up, also removed the cover so I can see all the way down the side of the engine.
I run the car for some time checking for an oil leak, nothing found though.
I'm thinking that maybe the sump plug isn't seated correctly, problem being getting under the car .
The car is still running like a beast, no issues with temps or oil pressure.
