What does it mean smoke coming out of oil dipstick?

White smoke from the oil dipstick signifies that you have worn out or bad piston rings. Besides the white or grey smoke that comes from the dipstick hole when a car’s piston rings go bad, it also manifests a few other symptoms.

Some of the symptoms include; excessive oil consumption, poor acceleration, poor engine performance, and loss of power.

However, the smoke coming out of the dipstick is a major symptom that you will easily identify. Kindly note that white smoke from dipstick in a diesel engine is pretty similar to the same problem in a gasoline-powered engine.

A dipstick is a metal measurement device like a flat rod with a plastic ring handle. It is used to ascertain the oil level in a vehicle’s engine. The dipstick also helps to know the engine oil condition, as well as the engine’s internal health.

Remember that engine oil plays a vital role in the performance and efficiency of the engine. Therefore, the importance of knowing the oil level per time cannot be overemphasized. Oil shortage can be very risky because of the damage it causes to a vehicle’s engine.

However, a worn-out piston ring is another challenge that needs an immediate response in order to curb imminent problems. The piston rings are responsible for allowing oil to lubricate the walls of the cylinder and other moving parts. However, it ensures that oil doesn’t enter the combustion chamber.

If these components wear out, break or get stuck, it will result in the oil flowing into the combustion chamber and burning during the combustion process. This automatically triggers the release of smoke out of the vehicle’s oil dipstick.

That’s why oil blowing out of the dipstick in a diesel engine is a major concern. Meanwhile, this challenge can also be seen in a lawnmower, especially when you overfill the crankcase with oil. This is usually the problem of smoke coming out of oil dipstick in a lawnmower.

How do you fix smoke coming out of oil dipstick?

If you’re experiencing smoke coming out of your car’s oil dipstick, fixing the problem is pretty easy. However, you must study the situation in order to note whether the smoke is a one-off or consistent occurrence.

If the occurrence is one-off, you don’t necessarily have a problem. Sometimes, condensation can be built within your car’s exhaust system when the car stays outside overnight.

This can cause the engine to release steam when you start it, especially in the morning the next day. If this is the case, you most likely do not have a problem at all. Also, your car’s engine and other components that get heated up by constantly working or hot temperatures can release steam when in contact with water.

Therefore, it is essential to know whether you’re interpreting steam as smoke coming out of specific vital components within your car’s engine compartment. However, once you identify that your car’s oil dipstick is truly giving off smoke, especially repeatedly, rectify the problem as soon as possible.

In order to fix the problem, kindly replace the worn-out or broken piston rings most likely responsible. The parts are quite inexpensive, ranging from around $30 – $200, depending on the vehicle’s make and model.

While some vehicle parts costs are relatively cheap, the labor cost of fixing the part can be five times the part purchase price. This is somewhat the case of bad piston rings in a car.

However, even though the parts cost less than half a thousand dollars, the labor cost is relatively expensive. It is estimated around $1,000 – $4,000. Nevertheless, the location and auto technician also determines how much you spend on labor cost.

Nevertheless, irrespective of the repair cost, fixing a smoking oil dipstick is vital to your car’s performance and efficiency. Bad piston rings can be characterized by several other negative effects.

Some of these effects include abnormal excessive oil consumption, gray or white smoke from car exhaust, loss of acceleration power, etc. These symptoms are warning signs that a bigger problem is imminent.

Therefore, neglecting the symptoms over a long period will cause more harm to your vehicle’s engine and other vital components. Of course, you don’t want to experience a total breakdown of your vehicle’s engine, because replacing a completely damaged engine can be very expensive.

So, if you’re experiencing any of these problems besides the smoking oil dipstick, replace the worn-out piston rings immediately.
