Hi, I have a 318ci se 2ltr 51 plate. I had smoke coming through the vents into the car. The rocker cover gasket has been replaced, oil filler cap replaced. Since I have driven the car 180 miles each way on Motorway trip good way to get rid / burn off excess. However I am still smelling the burning and get the smoke under the bonnet. The gearbox is fine to as its dry no leaks. Can anyone help?
