I thought...
Blue/Steele Gray Smoke was Oil
White is Water/Coolant
Black is too much Fuel
If is blueish, I think is burning oil.
Pull the Spark Plugs for signs of caked oil on them, or wetness. If you have a bad PCV valve can suck the oil from the Cylinder Head.
Another cause for that is bad Maintenance Practices, Abuse / Negligence or just excessive mileage.
PS... Too much oil in the exhaust can kill the Catalytic Converter, so expect to replace that too.
But I am more inclined that you have a bad PCV valve.
Do what Jerry said 1st.
