If it just suddenly started doing this, it could just be a crankcase vent system problem, make sure the PCV valve is operational and has good vacuum supply, then make sure the clean air intake portion of the system is completely functional and lines are clean. If the PCV system checks out, then it is possible that oil rings have failed, or the valve seal and guides are totally shot. Have you noticed any oil smoke out the exhaust just after start up or just idling?

I have not noticed any smoke upon starting or during driving. I have followed the car with someone else driving it. Your answer is most helpful and appreciated. Thank you.
