I'm a learner driver and constantly practising manouvres , but car seems to give off burning smell after constant practice. My car is automatic transition , / year is roughly around 2003 Vauxhall corsa
Hello there. Unfortunately, we don’t typically work on Vauxhall Corsas here in the U.S., but there are a few items that could cause a burning smell including a leaking engine or transmission oil, a "petrol" leak under the hood (as I believe it’s called abroad). If you’ve been driving in the same area for extended periods of time, it might also be caused by your tires or brakes getting overly hot. Keep up the practice, but if the issues continue, I recommend having a certified mechanic, such as one YourMechanic, come to your location to determine why the car is giving off this smell.

The oil is probably leaking down onto the hot exhaust system and burning off — leaving an odor but no drops. As long as the oil level doesn`t drop below a safe level, this leak isn`t harmful. But if you`re going to keep the car, I`d recommend having the gasket replaced.
If Your Car Smells Like Acrid Smoke Or Burning Oil
If you notice the smell not long after an oil change, the leak might be caused by a loose drain plug or filter that wasn`t properly attached—or an oil cap that wasn`t screwed on tightly enough.
Hello, You likely have a small oil leak on the valve cover, or another place that is leaking on the exhaust. Also, if the smell is sweet, like antifeeze, you may have a small coolant leak as well. Lastly, check smell the wheels to see if the brakes are the source of the smell.
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.
However, a bad PCV valve is a tiny, inexpensive part that can cause an engine to burn oil if it goes bad. Replacing it is fast and easy! If your engine is burning oil, hope that it`s due to a bad PCV valve.
If the burned oil smell is coming from the tailpipe (bluish white smoke), it is a symptom of oil leaking into the combustion chamber, which means it is getting into your exhaust system.
There are other indicators that will suggest you have an overfill problem, including blue exhaust smoke, a burning smell, an oil leak, or a high reading on your oil pressure gauge (if equipped).
More commonly, coolant will leak from cracked hoses or bad radiators, a far less severe problem. Leaking coolant has a sweet, warm smell, and is easily recognizable. It smells more like vapor than smoke, like the difference between steam from a boiling pot of water and smoke from a fire.
When your vehicle overheats, it shuts your plans down for the near future. You know the warning signs. The dashboard lights up like a Christmas Tree. You smell funny odors like burning rubber, scorched oil or boiling water.
Reason #3: Bad Catalytic Converter
It can stop breaking down the sulfur made during combustion. As a result, excess sulfur in the exhaust gas can often be detected in the cabin as sulfur has a distinct rotten egg odor.
Technically, you can drive your car with a burning smell, but you shouldn`t! No matter how small, any cause of a burning smell can potentially turn into something serious. More often than not, the burning smell, when ignored, could even start a fire, which can be pretty dangerous.
Failing Catalytic Converter (Sulfur Smell)
Over time, the catalytic converter can become overheated, contaminated with gasoline in the exhaust or simply wear out. When this happens, you`re likely to notice a rotten egg, sulphurous smell coming from the exhaust.
One way to check whether a PCV valve is functioning is to remove it from the hose or tube and shake it. If you can hear a metallic rattling noise, it`s likely in good working order. If you do not hear anything when you shake the valve, it is likely that it is no longer opening and closing like it should.
Vinegar: If the oil smell in your home was due to a problem with your furnace and not a spill, you can mitigate it by placing dishes of vinegar near your furnace and in front of each vent. Replace each with a fresh container of vinegar every day until the smell is gone.
Clogged PCV Valve
When the PCV valve becomes clogged, it can cause oil to be pushed out of the engine and onto hot engine components, creating a burning oil smell.
Another common cause of burning rubber smells could be due to coolant leaking onto the engine and whenever this happens, the coolant will give off a burning rubber smell when you stop the car. Leaks in the radiator can cause a serious problem because it helps keep the engine temperature at optimum range.
If you notice the odor of burning plastic, smoke, or melting wires, this could indicate that your transmission is overheating or that the transmission fluid is burning. Worst case scenario, this smell could lead to an electrical fire, which is incredibly dangerous for you and other drivers on the road.
Some common signs of a leaking head gasket include: Coolant puddles under your vehicle. Low coolant level in your reservoir. A strong, acrid smell when your engine is hot – some describe this as a “sweet” smell coming in through the car vents.
The filter is clogged: In addition to making your system work less efficiently, a clogged filter can also can cause the system to produce a detectable oil smell. Replacing the filter is often enough to fix the issue.
Blue smoke from the exhaust: Bluish smoke can indicate your car is burning oil during the combustion cycle. Burning oil smell: A thick burning oil smell could mean oil is seeping onto hot engine parts. Frequent low oil light warnings: Regular low oil warnings can indicate excessive oil consumption or a car burning oil.
White smoke in the tailpipe can indicate coolant entering the combustion chamber of the engine.
Burning plastic smell: From plastic valves to rubber seals, vulnerable engine components may begin to melt as your engine overheats, emitting the smell of burning plastic. Sickly sweet car smell: The coolant in radiator fluid is ethylene glycol, which is molecularly similar to the sugar compound.
If you notice a burning rubber smell from cars, it is often a sign that you have overheated the brakes or tires. Overheating usually occurs when your car`s clutch is slipping or not working properly. If you experience this smell and were using your clutch at the time, let the car cool down, and try again.
It gets even more concerning and confusing when car overheating suddenly returns to normal. This phenomenon can happen for many reasons, like a bad thermostat, a faulty radiator, or a coolant leak. As such, it`s best to get your car checked by a professional— like RepairSmith!
