Burning oil is most likely the source of any odor coming from behind the hood that smells like tar or asphalt. There can be an oil leak if it seeps onto the engine’s components and burns off. Additionally, while the engine is operating, oil could enter the fuel system and burn. This might occur if a gasket fails.

Why is smoke coming from beneath the hood of my car?
Your car’s hood is emitting smoke, which is an immediate indication that something is certainly wrong. It may be an indication of a little problem or a serious issue with your car. After sitting over night, it’s typical to observe a tiny white puff of smoke emerge from your tailpipe. Only water vapor exists. As water interacts with the radiator or exhaust on a rainy day, steam may also be visible pouring from the hood. However, you must stop right away and take a look if you are driving and suddenly smoke appears to be coming from the engine or tailpipe.
It’s crucial to initially comprehend what the color or scent of the smoke suggests before you start to fear. You can decide whether to keep driving or seek the advice of a repair shop by determining the cause.
The Cap for Oil Filler
Older engines frequently see white smoke coming from the hood while the engine is not overheated. Almost all engines’ oil filler caps give off a faint smell of smoke, which is a byproduct of the burned fuel inside the engine. More hot spots are produced by older engines, which causes the car to smoke beneath the hood without overheating.
The factors behind this smoke problem include blocked PCV tubes or valves and worn-out piston rings. As a result of the worn-out rings, the pistons suck fuel into the cylinder, where it burns and produces smoke. After then, the smoke bypasses the piston rings. The smoke is expected to be drawn back into the engine by the crankcase ventilation so it can restart burning. However, when either the PCV tube or valve is broken or obstructed, this does not take place. In that situation, the oil filler lid allows the smoke to escape.
What causes BMW’s engine to smoke?
In most instances, persistent white smoke points to a coolant leak. Smoke from the Exhaust is Blue: Your car is burning oil when you see blue or dark gray smoke. It may be caused by deteriorated pistons, broken seals, a blown gasket, or an inoperable PCV valve.

Engine Smoking Leaking Coolant – If you notice white smoke coming from under your hood, it most likely comes from burning coolant that has contacted the hot parts there. This smoke has a pleasant aroma.
Why is my car’s hood smoking but it isn’t overheating?
The most typical response to the question “Why is my car smoking but not overheating?” is that an engine has come into contact with some sort of fluid. This can include coolant, motor oil, petrol, transmission fluid, and condensation. Due to the engine fluid being burned off, it may cause your engine to smoke.
Why is my car burning all of a sudden?
Overheating in automobile engines frequently results in smoke. Defective wire casings, hot residues on the engine block, and hot liquids like oil, transmission fluid, and brake fluid can all contribute to this.
Your cooling system can also be broken, or your engine might not have enough lubricant. Find a reputable garage to have a look, whatever the issue.
How do you handle a smoking hood?
Ideally, you’ll be able to save this information about what to do in the event of a car fire in your memory under the heading “nice to know, but not needed.” Many Northern Virginia drivers experience anxiety and panic when they smell smoke, and for good reason. Things can quickly go from bad to terribly terrible when a car fire starts in your engine. Here is what to do if you do find yourself in the middle of an automobile engine fire.
- Stop the car right away. Where there is smoke, there is fire, and if your hood is producing smoke, you at least have the early stages of an engine fire. Turn on your hazard lights and pull off the road safely so that other drivers will be warned to drive carefully.
- Put the car in park, engage the parking brake, and shut off the engine. The additional heat produced by a running engine can worsen the fire’s effects and, in certain situations, even ignite the fire and spread it farther. Setting the parking brake will stop the car from rolling into oncoming traffic but has no effect on the engine fire.
- Quickly step away from the car. Move away from the vehicle at least 100 feet as soon as you can. If the gas tank ignites during the engine fire, an explosion is always possible as well. The engine fire will cause parts to melt and produce gases.
- Alert the appropriate authorities. As you assess your surroundings, make note of mile markers, cross streets, crossroads, interchanges, and any other identifying markings. Then, call 9-1-1 and let the operator know where you are and what caused your engine fire. A prompt response and any necessary assistance are ensured by providing the most precise information.
- Stay outside the car. Even though your favorite sweater or electronic equipment might be inside the car, you shouldn’t risk getting hurt while there’s an engine fire present. You don’t want to risk getting hurt trying to get goods out of the car since you don’t know what will happen with the engine fire.
One approach to help prevent engine fires and keep you safe on the roads is through proper auto maintenance. For a thorough safety inspection and the assurance that you, your family, and friends will always be as safe as possible when traveling, stop by Wiygul Automotive Clinic right away.
Why does my car smell like burning and is it smoking?
For two reasons, an oil leak is hazardous. First, a fire might start if it collides with the exhaust. Low oil levels may also harm the engine. If the stench appears soon after an oil change, it may be the result of a leak in the oil cap, a loose drain plug, a filter that wasn’t correctly installed, or other components. A poor gasket or seal that allows oil to leak might lead to issues like oil spilling on the timing belt or the crankshaft seal. In any case, it is not something to disregard. Trotta warns that it “may completely take your engine out.”
Can I drive my car if the hood is smoking?
While driving, if you notice smoke coming from under your hood, you should stop as soon as it’s safe to do so. To determine if it is safe to drive to a repair shop or if it is safer to hire a tow truck, turn off the engine and raise the hood to look inside and see what might be wrong.
Why is my car spewing out a lot of thick white smoke?
In general, thin, white exhaust smoke that resembles water vapor may not be a cause for concern. Depending on the weather, condensation may accumulate inside your car’s exhaust system and steam may be produced by the heat moving through the pipes.
You might have a problem if your exhaust system is spewing out a lot of thick, white smoke. This dense smoke is frequently the result of coolant burning because of problems with the engine, such as a fractured engine block, broken cylinder, or blown head gasket.
A coolant leak that could result in overheating and seriously risk causing harm to your engine is typically indicated by thick white exhaust smoke. If this is the case, give our auto repair business a call right away to schedule an inspection.
How should I handle a smoking car engine?
Do not continue driving if smoke is seen coming from the car. As soon as you can, stop on the side of the road and turn the engine off. Check to see if you can add fuel to the vehicle and restart the engine if there is also low oil pressure.
Can a car smoke due to low oil?
Blue smoke is typically brought on by oil leaking into the engine and burning with the fuel. Additionally, the oil in your engine will be low. Additionally, it’s possible that the exhaust system is being contacted by an external oil leak.
White smoke—is it an engine issue?
Finding out precisely when smoke is flowing from your car’s exhaust is the first step. If it only occurs when you accelerate, it might be a different issue than if it only happens when you are moving or if it occurs consistently when the engine is running.
The next step is to try to identify the type of smoke after figuring out when it happens. Is it white, grey, or just a little bit blue? Or is it dark and dense? Once it’s in the air, does it immediately evaporate? Or does the smoke linger and have a foul odor? If it’s black smoke, does that mean that when the car is stopped, soot is left on the road beneath the exhaust tip?
The primary reasons for smoke coming from an exhaust can change based on your car and how it is maintained. Any visible exhaust emissions are probably nothing to worry about if your automobile is kept up well and serviced on a regular basis, but it is still worth examining.
The actual problem is with badly maintained vehicles since smoke from the exhaust can be a telltale sign of carelessness. This might be a helpful tip when purchasing a used automobile because a smoking exhaust can be an obvious symptom of underlying issues if the service history is lacking.
Depending on whether your automobile has a diesel or a gasoline engine, the smoke you see may be created by a variety of things. If you drive a hybrid, you might also notice that something is coming out of your exhaust that you weren’t expecting.
To make it easier for you to immediately determine what issue is causing each type of smoke, we have divided the various types of smoke you may encounter. We’ve also mentioned whether a remedy is required and how expensive a patch would be. You can scroll down the page for a more detailed explanation, but the summary for each form of exhaust smoke are just below.
- White smoke coming from the exhaust could be condensation-induced steam from the exhaust pipe or a more serious problem from an engine coolant leak. White smoke in excess could be a sign of a failing head gasket.
- Blue exhaust smoke indicates the burning of oil. There are several potential causes, with worn piston rings, valve seals, and turbochargers being the most serious ones.
- Grey exhaust smoke could be caused by too much oil, a broken PCV valve, or a transmission fluid leak in automatic vehicles.
- In a petrol vehicle, black smoke from the exhaust implies that too much fuel is being burned and may indicate issues with the air filter or fuel injectors. It’s more likely to be soot accumulation or the diesel particulate filter cleaning itself in diesel vehicles. A longer drive should give the filter time to clean itself and fix the issue, ideally on a highway where greater speeds and revs are possible.
Can smoke harm a car’s engine?
Vehicle fires can result in significant damage and jeopardize a driver’s safety. Smoke, however, typically does not seriously harm a car’s engine. Although the engine may suffer some damage, the vehicle’s power may be badly affected.
