Perhaps valve cover gasket is leaking oil onto plug area
Could be a bad head gasket. You would get engine oil leaking into the cylinder heads and that would show as smoke out the tail pipe.
Most likely you have a blown had gasket.
If it only smokes at startup and the smoke is blue this is normally a sign of worn valve seals or guides. White smoke is a symptom of blown head gasket. Black smoke is a symptom of overly rich fuel/air mixture.
Oil always worked for me!!! ....You might have blown your headgasket! This means that your engine coolant is leaking into the oil in the engine and it causes smoke out your exhaust.
Shut the car off and get out. Something is broken and if its producing smoke, it could catch on fire.
First off, the color of the smoke will tell you quite a bit and also if it is safe to continue driving the car. Black smoke indicates an overly rich fuel mixture. Blue smoke indicates it is burning oil. White smoke indicates there is coolant entering the combustion chamber. White smoke, stop driving the car immediately as severe engine damage will occur. You probably have a blown head gasket. Black smoke, drive as little as possible until you can find out what is wrong. The overly rich fuel mixture can do damage to the catalytic converter, O2 sensor, and possibly cause the engine to run hot. So keep an eye on the temperature gage. Blue smoke, may foul the plugs, so drive it until you get a diagnosis from a professional as to what the problem is.

sounds like a leak in your transmission cooler lines. check the smaller hoses going to the radiator usually the bottom.

At a decent shop, approximately $530.00 for diagnosis, smoke test and replacement including new plugs. This is for a 2002 5.7L V8.
