Blue smoke out tailpipe when I stop or idiling

IT BURNED THE THREE QUARTS OUT THE TAILPIPE IN BLUE SMOKE. CHECK THE PVC. OPEN THE RADIATOR CAP WHEN THE ENGINE IS COLD AND LOOK FOR THE PROPER COLOR OF THE COOLANT. SPARK PLUGS ARE FOULED BY OIL

New motor or head work

could be pouring gas

Sounds like you may have ruined the piston rings and this is allowing oil to seep in to the combustion chamber hence your smoke. Or if it overheated when you ran out of oil it is possible that you have a bad head gasket now. Check both your coolant and oil for signs, oil will have a white froth, or darkening of your coolant. Hope that helps you.

Smoke oil? For what your thinking that is oil? Smoke coming from the tailpipe is not good news, but does not necessarily mean the engine needs rebuilding. First, you need to determine what color of smoke is coming from the tailpipe
* White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area.
* Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe.
* Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm.


If you confirm us that is oil smoke, check and keep in mind that the car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

Helllo there
Symptom: Gray or blue smoke from the exhaust. You notice gray smoke coming from the exhaust when you start your car. The smoke may or may not disappear after the car is warmed. If it is, it is less noticeable. The smoke may have a bluish tint to it. Possible causes:

1. The engine's piston rings may be worn.
   The Fix: Replace piston rings. (Generally not a DIY job)
2. The engine's valve seals may be worn.
   The Fix: Replace valve seals. (Generally not a DIY job)
3. Damaged or worn valve guides.
   The Fix: Replace valve guides. (Not a DIY job)

Symptom: Engine uses more oil than normal, and there is some smoke from the exhaust. The oil level is low between oil changes. It appears that the oil is being burned by the engine because of the smoke in the exhaust. You may or may not notice the engine doesn't have the same power as it used to.
Possible causes:

1. The PCV system is not working properly.
   The Fix: Replace PCV valve.
2. The engine may have mechanical problems.
   The Fix: Check compression to determine engine condition.
3. The engine's piston rings may be worn.
   The Fix: Replace piston rings. (Generally not a DIY job)
4. The engine's valve seals may be worn.
   The Fix: Replace valve seals. (Generally not a DIY job)

So upon startup the car has a little smoking going out the tailpipe? Then it goes away after the car warms up a little? You probably have stuck piston rings and are burning oil at first until the car warms up and the rings seal better. What kind of oil are you using? What weight is it? I don't know what is in the car, but if it is conventional oil at 10w-30, try changing it to synthetic and using 5w-30. I don't know what that car comes with from factory or calls for, but in my experience I've stopped oil burning in a piston engine with thinner, synthetic oil. This helps to unstick the rings allowing them to seal better AND the thinner oil doesn't collect on the rings so much, keeping it from burning or going out the tailpipe. Also, synthetic doesn't burn and carbonize like convention oil (dinosaur juice) does.

I really hope I understood your problem and helped you with it. If not, please clarify. Good luck!

Blue smoke means oil is being burned
do a compression check

you probably have low compression on one or two clyinders causing blow by which would be where all your blue oil smoke to be coming from

hi nishga
im dave; hope i can help

First you need to determine if it is actually black smoke or if it is blue smoke. There are three colors of smoke that can come from the tailpipe. It is not white smoke obviously because that is easily differentiated from blue or black and generally indicates water or antifreeze leaking past the head gasket and into the compression area of the motor. White smoke is the steam of the water/antifreeze being emitted

Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles. The car has many seals, gaskets, and o-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plugs, it will cause a misfire(engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

Black smoke is caused by excess fuel that has entered the cylinder area and cannot be completely burned. Another term for excess fuel is "running rich". Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a heavy fuel odour in the engine compartment. Some of the causes of excess fuel are a carburetor that is out of adjustment which is not likely unless you have installed an aftermarket carburated system on your non-carburated car, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or emissions sensor. If black smoke is present, check the engine oil to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Check the above mentioned systems and after detecting the trouble replace the faulty parts and then the engine oil and filter.
