Blue smoke is the oil seeping by the rings. Thus getting on top of the piston burning up and going out the exhaust. Sounds like the car has many miles on it.This is a sign the motor is worn and getting old.Keep a eye on the oil level and save your money for new ride. Hope this helps . good luck

It is a sign of oil burning. If the power is good it might only be the valve seals. Check the compression by removing the spark plugs and installing a compression tester. These are available at most auto part stores. I had a car that would burry the car behind me in blue smoke after sitting at a stop light. The car was a 1988 Doge Dynasty (Mitsubishi engine). After I pulled the heads and brought them to a machine shop, the car stopped burning oil.

Simple-ring wear.Here's a quick test-go up a hill.If it smokes going up,it's your rings.If it smokes going down(do not give it any gas,just coast)it is your valves.End of story.
