You are burning something but, are you sure its oil? Are you adding oil on regular basis? Or, are you adding antifreeze on a regular basis? Replacing valve seats involves work on the head and replacing the head gasket. If its antifreeze you are burning you probably need only the head gasket replaced. Both will start you at about $500, depending on where you are located. But the valve seats typicaly require a maching shop which is more $$$. If it is oil have you tried oil additives for smoke? They SOMETIMES work.
