I agree, back in the 80's and 90's GM had a big issue with the valve stem seals wearing on cars that were only a couple years old and less that 50000 miles. You would be surprised to know how many GM parts are on you Carolla, thought I have no Idea about the valve stem seals. That said, it only costs a few extra bucks to change to a high mileage oil, or use some sort of restorative agent, but would cost hundreds to replace you valve stem seals. Then If it still smokes, you can do the repairs.
By the way, if you do the seals, it would be a good time to replace your timing belt and water pump, if you are due, or near due for it. Also mace sure you get your valve lash adjusted if applicable.
