Hi, I have a 2009 1.9 jtd. I have what looks like fresh oil spray around the right hand side of the engine bay. Engine oil level is fine and no leaks under the car. Anybody have any advice please of what to check? All obvious fluid levels are good. Not sure how to check the gearbox oil level but gears are fine. Can't see or feel any split hoses. I have cleaned the area to see if it comes back. All advice gratefully received...
