Try this: Accelerate to at least 50mph and at least 5500rpm and take your foot off the gas quickly. Look in the rear view mirror. What do you see? Nothing. There is a big blue cloud blocking the view. If this is the case, and if you are NOT consuming large amounts of oil, it is your valve guides. If you are consuming oil as well, get the oil seals checked. If they are OK then you have a more serious problem and should go further and check your compression and any other potential trouble spots. You can live with worn valve guides for quite some time since they neither eat lots of oil nor do they let contaminants into the oil. If the engine is othwise in good shape and you are tired of seeing smoke come out of your car, having the valve guides replaced (if they are replaceable) should not be too costly, $200 to $300 I imagine.
