My 93 Buick Regal limited is smoking under the hood on the driver side

While I'm driving smoke comes out the hood while driving after 20 or so minutes. No check engine light, no low oil light, please help

My car has 218 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hello there. Smoke rarely comes from the engine bay, and if it does, the issue is typically critical already. If there is a problem within the engine that produces smoke, that smoke will exit the engine through the exhaust. In many cases, a leaking valve cover gasket might produce smoke caused by oil dripping on a hot manifold. If the leak is large enough, you will likely see the oil dripping on your driveway or garage floor. It is also possible that a coolant line has a small leak, which could also produce some smoke. The best way to know for certain is to have a professional mobile mechanic come to your location and complete an engine is smoking inspection.

How to Identify and Fix Common car Problems ?

An engine smoking or white smoke under the hood could be caused by any number of problems including: Inoperative cooling systems. Car burning oil. Damaged valves, pistons, or wiring.
The most common answer to, “Why is my car smoking but not overheating?” is that there`s a type of fluid that`s landed on the engine. This can be motor oil, fuel, transmission fluid, coolant, or even condensation. It can cause your engine to smoke because it`s burning off that fluid from the engine.
The most common cause of smoke under the hood is small amounts of motor oil or other fluids accidentally spilled or leaking from a bad gasket or seal onto a hot engine or the exhaust system. Those other fluids may include engine coolant, power steering, brake and transmission fluid, even window washer solvent.
The steam that you noticed is due to the water splashing onto the hot exhaust system. The exhaust system components and piping are so hot that any water hitting them will instantly vaporize and create a noticeable cloud of water vapor. If the vehicle operates normally now, in all probability nothing is amiss.
What to Do If You See Smoke. If you notice smoke coming out of the vehicle, do not keep driving. Pull over to the side of the road as soon as you can and shut the engine off. If there`s also low oil pressure, see if you can add some fuel to the car and restart the engine.
If your car smells like burning rubber, turn off the engine and check under the hood to see if anything looks out of place. Chances are that the smell results from a belt or other part slipping and rubbing against the hot engine. If you can`t identify the problem, take your car to a mechanic.
The radiator prevents overheating by cooling the fluid that flows around the engine block to dissipates the engine`s heat. When you see smoke coming from the radiator, it is an indicator that the radiator has not been able to do this job and the car is overheating as a result.
Without enough oil, engine components will start to rub against each other and produce excess heat. Any oil that is left will start to burn up, producing the motor that you smell. The aroma is strong enough for you to notice even inside the passenger cabin. Smoke appears under the hood.
Only Use Water In The Radiator In An Emergency

If it`s really low or actually empty, you need to add fluid to your vehicle. While it`s ideal to add a 50/50 mix of coolant and water (or a pre-mixed coolant), if you absolutely have to keep driving, you can add water to the radiator to get you to your destination.

Technically speaking yes you can use plain water in your cooling system but it isn`t recommended as a long term solution and certainly not in extreme weather conditions.
One possible reason for white smoke coming from your car`s exhaust is that the engine is burning oil. This can happen if the oil level in the engine is low or if the oil seal is leaking. If you notice that your car is burning oil, you should take it to a mechanic to have it checked out.
This means that the fuel injectors are either adding too much fuel or that the intake valves aren`t letting enough air in. This could be caused by a leaking fuel injector, a faulty fuel pressure regulator, or a bad air filter.
Black smoke leaving your engine is often a sign that too much fuel is being burned. It could also be caused by a clogged air filter. If you catch either fault early, they are usually easy to fix.
Wynn`s Stop Smoke is an oil soluble supplement designed to reduce exhaust smoke due to oil burning. Applications: For petrol, LPG and diesel engines. For cars with excessive blue/grey exhaust smoke due to oil burning. Especially effective in older engines with worn components.
Summary. If your car emits a rotten egg smell, there might be a problem with the catalytic converter, fuel pressure regulator, fuel filter, or even the old transmission fluid. Whatever the cause, if you get the rotten egg smell in your car, take your vehicle to the mechanic as soon as possible and resolve this problem.
If your car smells like acrid smoke or burning oil, it could indicate a problem with the engine`s piston rings, leading to reduced fuel efficiency and even loss of engine power. Mechanics can diagnose and fix this issue by replacing the piston rings or valve seals.
Overheating will ruin an engine in short order. If you decide to pop the hood, do so with extreme caution. It`s better to shut the car off and wait for it to cool down; you don`t know which direction the jet of steam is coming from, and the leak could get worse at any time before the engine cools off.
Low coolant can sometimes cause a head gasket on your engine block to blow. If this happens, you may notice smoke emitting from the engine or tailpipe, a loss of power, engine knocking sounds, or decreased efficiency.
A burning smell in your car could be caused by several things, including a burned-out electrical fuse, an overheating A/C compressor, or worn out brake pads that need to be replaced.
White engine smoke is commonly caused by burning radiator fluid (also known as coolant or refrigerant). You might also notice a sickly sweet smell (often compared to that of butterscotch or maple syrup).
No. It is, in fact, dangerous to drive with a smoking alternator. A bad alternator can cause serious damage to your car`s electricals as it can transmit alternating current. Furthermore, it could also catch fire and spread across the whole engine compartment.
However, if you notice that you have blueish smoke coming from your exhaust, it`s a sign that there`s something wrong. Generally, blue smoke is caused by oil seeping into the engine and being burned along with the fuel.
No. It is, in fact, dangerous to drive with a smoking alternator. A bad alternator can cause serious damage to your car`s electricals as it can transmit alternating current. Furthermore, it could also catch fire and spread across the whole engine compartment.
If your car has an exhaust leak, it is not something you want to take lightly. The performance of your vehicle will be hindered. More importantly, it can potentially be deadly for you and your passengers if carbon monoxide and other harmful fumes are leaking inside the vehicle.

Driver side door lock button not working, and passenger side sliding door makes a buzzing noise
ANSWER : Hi there. These door issues are common on this vehicle. Most of the time the main issue is the master door lock switch on the driver door. It sounds like you already replaced that. As for the sliding door problem, most of the time, this is a failure within the door module or it can be a connection issue.

I typically take the door apart and check the connections on the module and inside of the door just to make sure that there is nothing apparent in there. If the connections and the wiring are fine, then I use a scan tool to check the module to see what the inputs and outputs are doing. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your door problem and recommend a repair.

Driver Side Inner & Outer Tie Rods and driver side strut being bent.
ANSWER : From what you’ve described, the damage was most likely caused from hitting a pot hole. If the damage was from a pot hole on the right side, in some cases it’s possible for the force to transfer over and damage the left side as well. If you’d like a second opinion on this, consider YourMechanic, as a certified technician can come to your home to diagnose your car’s suspension system and confirm these suspicions.

Car shut off while driving, smoking (or steam) from right side under hood, strong burn smell, check engine light on until next day
ANSWER : Hi there:

It’s very difficult to diagnose exactly what type of damage may have been done to your 2003 Honda Civic during the overheating issue without physically inspecting this onsite. It is possible that the head gasket may be damaged, which might be why you add coolant but don’t see a leak. If this has occurred, you most likely have suffered serious engine damage. To know for sure, you should have a professional mobile mechanic complete a car is smoking from engine or exhaust inspection; so they can trace what might be wrong with your car and recommend the right repairs.

Power mirror on passenger side will not retain it’s setting driver side works perfect.
ANSWER : A technician with an advanced scan tool can verify the issue. The mirror system is complex and involves many modules. The Body Control Module is a possible cause, but it’s doubtful; replacement requires reprogramming, which requires special equipment. I would check the driver’s and passenger’s door modules; toggle or move the switch on the driver’s side to see if it causes the problem, and ensure that the mirror glass itself is not loose on the passenger’s side mirror assembly.

Without diagnosing the problem with advanced equipment, the issue is hard to diagnose. A qualified YourMechanic technician can show up to the location of your vehicle with a scan tool to inspect and diagnose your power mirror issue.

Front driver side tire moves side to side when jacked up
ANSWER : If you can move the tire in and out when on a jack then you may have a few different possible problems. The inner or outer tie rod ends may be worn. Your steering gear may also have worn bushings. I would recommend moving tire back and forth while holding onto the tie rod ends to see if looseness is felt and replace any loose components. An alignment will need to be done after repairs.

2012 fusion ddamage front pass side trunk shifted to the drivers side. Is this possible
ANSWER : Request that a professional alignment shop use a tram to carefully and completely measure the unibody and compare all such measurements against the data set out in detail in your vehicle’s Factory Service Manual. Using that strategy it will be easy to conclusively and authoritatively determine if the unibody is damaged. If the unibody was damaged in the collision it will have to be repaired, if cost effective, or obviously the insurance company will have to make you whole on your claim for damage. If you have any further concerns, do not hesitate to contact YourMechanic as we are always here to help you.

Lowbeams on drivers side will not shut off
ANSWER : Hey there. To be completely honest my friend, you might need to go back to the basics and purchase a detailed wiring schematic for this vehicle to determine where the electrical fault exists. Quite often when an electrical fault like this exists, the best solution is to trace every connection to see where the fault is triggered. Most of the time, it’s an exposed wire or ground issue that causes the circuit from the switch to the lights to fail.
