Chances are if you are blowing blue smoke, you are burning oil.  Another cause of blue tint smoke is you are burning to much fuel and not enough air.  If the engine does not act erratic or acts like it is flooding out, then I would say you are burning oil.  The most common problem found with burning oil is either worn piston rings, bad valve seats/seals.  If the engine has high mileage, I would recommend any type of oil treatment.  Change your oil, filter included, use some form of engine treatment, run it for a few hundred miles, and rechange your oil and filter again.  If your engine has over 100,000 miles, I would highly recommend using an oil that is made for high mileage engines.  As this oil has additives that will help ease the aging engine.  If this doesn't work for you, I would say you need to have the rings and valve seals replaced.  You can do this yourself with a little knowledge of engines and pick yourself up a Haynes Manual at your local auto parts store if you do not already have one.  Hope this helps.  Feel free to comment if you need more assistance.  Please don't forget to rate.  Thanks!

What could blue tailpipe smoke be from?


Your issue could be a few things. Simplest first would be the PVC valve. Other issue would be valve seals, valve guides or piton rings. The blue smoke is from your vehicle burning oil

2001 Ford E-250 has excessive oil consumption with no visible leaks and has a p301 misfire code


Do you notice any blue smoke out the tailpipe?
The P0301 code means you have a misfire in cylinder 1. If I were to put these two symptoms together, I would guess that there is oil leaking into the cylinder, which is causing it to misfire. The oil then burns out the back.
If this is the case, it is probably because your spark plug tubes are leaking. Replacing the valve cover gasket or spark plug tube seals (some cars have a valve cover gasket that has the tube seals included) will solve the problem.

You can check for the leak by pulling the spark plug wire out of that cylinder and seeing if it is oily. If it is, there is your leak.

This is just a first guess. Let me know what you find.
Also, let me know about whether or not your tailpipe has blue-colored smoke coming out.

1992 es300 blue smoke from exhaust


The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. So best bet is to have a local repair shop inspect for internal oil leakage.

1999 saturn sw has blue smoke coming from tailpipe. I would like to know if it has anything to do with head gasket


blue smoke is usually oil burning- is it light or heavy- if light- change oil and go up one grade- rings are worn- if heavy- time for a rebuild- rings need to be replaced. but for the money on rebuild- could find car newer and lower milage

2005 3.5l some times smokes oil then stops


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.

Blue Smoke: 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. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles.

How did the engine oil get inside the cylinder in the first place? 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.

your engine has worn valve guides, piston rings An engine that burns a lot of oil (more than a quart in 500 miles) is an engine that needs to be overhauled. Normal oil consumption should be a quart or less in 1500 miles. Most newer engines consume less than half a quart of oil between oil changes (every 3000 miles). So if your engine is burning oil, it's essentially worn out and needs to be repaired.
Because the cost of overhauling or replacing an engine often exceeds the value of an older car or truck, many people will just keep on driving a "mosquito fogger" in spite of the blue clouds of smoke it leaves behind. Never mind the pollution it causes, oil is cheaper than a new or rebuilt engine they reason. That philosophy may be okay if you live out in the sticks somewhere. But in urban areas that require periodic vehicle emissions testing, an engine that's burning oil usually won't pass the test because of excessive hydrocarbon (HC) emissions. You may get by on a waiver after you've spent some money (in vain) on a tune-up, but the fact remains you're still a polluter.
An engine that burns a lot of oil will also eventually foul the spark plugs. Thick, black oily deposits build up on the plugs until they cease to fire. Then the engine misfires and loses power. Cleaning or changing the plugs may temporarily solve the problem, but sooner or later they'll foul out again.
Forget about "miracle" oil additives or pills that claim to stop oil burning. They don't. Better to save your money and put it towards a valve job and new set of rings.

Sputtering during idle blue smoke


You are burning oil, causing the blue smoke. It is mainly cause by worn piston rings. Also will coat your spark plugs with oily residue. Try an oil additive such as "stop smoke" or another such brand to reduce burning your oil and it may recondition your seal sand stop it all together.

Thick blue smoke. no oil leaks new spark plugs and spark plug wires. checked all cylenders cant figure out why its smoking.


Hi! Chris, There are many causes of oil burning or exhaust smoke. There are three different causes of normal oil burning, 1; worn valve guides (smoking during deceleration), 2; worn cylinders and piston rings (smoking during acceleration), 3; split or worn out valve seal, or damaged intake manifold gasket (smoking all the time). Of course there are several variables in this equation. Sometimes coolant can also get into a cylinder and cause a blueish smoke. If you remove the spark plugs and use a pressure pump on the coolant system (radiator), coolant should leak into the intake manifold or cylinder. Coolant leaking into the intake manifold will leak into several cylinder through the valves. So, what year and how many miles are on the Jaguar?
