My 3008 has a severe oil leak, I originally thought it was the crankshaft oil seal, because I could see oil dripping quite fast from that vicinity when viewed from above. Now I've had the bottom tray off and cleaned up the mess, which was everywhere ! With the engine running, the leak is coming from the back of the engine somewhere. I'm hoping there's a breather up there somewhere. Any help you can give will be much appreciated.
