Question by  Tessa68 (51)

Why do I still see smoke after changing the plugs on my Neon?


Answer by  crudsturbo (47)

That is probably because the oil rings on the pistons are bad. They are there to keep oil from getting in the head to prevent smoking.


Answer by  nate (199)

it depends on the color of the smoke you got coming out. if it is a white smoke you are probably burning antifreeze which could mean you have a blown head gasket.

Your engine is likely suffering from worn or damaged valve seals or piston rings. Worn or damaged valve seals will typically smoke primarily upon starting the engine, whereas worn or damaged piston rings will tend to smoke steadily as the engine runs.

Well hopefully you just got a little oil in the cylinders when you changed them. You may need to check the gaskets on the valve cover. It might be a good idea to make sure you pcv vent isn't clogged.

Your engine is junk. It could be a number of things from bad rings to bad seals. You're losing oil or antifreeze somewhere in the engine that is burning itself out the exhaust. The color of smoke would be helpful to futher diagnose your proplem with the car. Let us know.


Answer by  Amber40 (24961)

Well typically worn spark plugs would not make an engine smoke. Smoking is usually a sign of a leak. Either coolant or oil is burning in the combustion chamber. If it is white smoke then it's probably coolant but blue smoke is usually oil.


Answer by  Motivator1 (89)

The plugs have no bearing on creating or sourcing the smoke. The smoke is derived from oil passing through the valves, valve seats or piston rings excessively. When it comes in contact with the plugs it is burned if the problem hasn't already fouled the plugs out. You need to source your oil leak to stop the smoking.

You are probably seeing smoke because you are burning oil real bad. You should check the oil and make sure the coolant is not in the oil.


Answer by  Steven (309)

Its most likely the oil residue burning off the new plugs and the plug cylinders. If the oil does not go away bring it in to get looked at.

You need to have it checked out by a professional person. They would know what is wrong with the car.
