What You'll Learn
Oil pan leaks can cause a burning smell
An oil pan is a container that holds excess oil dripping from the engine. Oil pans are designed to catch oil leaks and prevent oil from dripping onto the ground or other parts of the vehicle. However, oil pans can also leak, causing oil to drip onto hot engine components and potentially leading to a burning smell.
Oil pans can develop leaks due to various factors, including wear and tear, loose or faulty seals, and damage to the oil pan itself. Over time, the seals and gaskets around the oil pan can deteriorate, loosen, crack, or shrink, allowing oil to seep out. A damaged oil drain plug gasket is another common cause of oil pan leaks.
When an oil pan leaks, oil can drip onto hot engine components, such as the catalytic converter or the exhaust system. The high temperature of these components can quickly burn the oil, resulting in a burning smell. Oil leaks can also cause low engine oil levels, affecting the lubrication of metal parts and potentially leading to engine damage.
It is important to address oil pan leaks promptly to prevent further issues. Repairing an oil pan leak can range in cost from \$100 to \$2,000, depending on the extent of the damage and the labour required. In addition to the financial cost, oil leaks can pose a safety hazard, as they can increase the risk of engine fires or damage to vital vehicle systems. Therefore, it is recommended to have a mechanic inspect the vehicle and make the necessary repairs to resolve the burning smell and ensure the vehicle's safety.
To summarise, oil pan leaks can cause a burning smell by allowing oil to drip onto hot engine components, which can quickly burn the oil. Addressing oil leaks and regularly inspecting the vehicle for any signs of damage or wear and tear is crucial for maintaining the vehicle's performance and safety.

Regularly check your oil dipstick
Regularly checking your oil dipstick is an important part of car maintenance. It is a simple, quick, and inexpensive way to ensure your engine is running smoothly and can help you avoid costly repairs. Here are some reasons why you should regularly check your oil dipstick:
Avoid Engine Damage
Checking your oil dipstick allows you to monitor your engine's oil level. Insufficient oil can lead to increased friction and wear on the engine's internal parts. By regularly checking the dipstick, you can ensure that your engine has enough oil and avoid potential damage.
Detect Abnormal Oil Consumption
The oil dipstick can help you identify abnormally high oil consumption. If you find yourself frequently adding oil between regular oil changes, there may be an underlying issue. The dipstick serves as a gauge, and if you notice a rapid decrease in oil level, it may be a sign of a leak or other mechanical problem.
Identify Contamination
The oil dipstick can also help you detect contamination in your engine oil. Water and coolant contamination are common issues that can be identified through dipstick analysis. Water in the oil can lead to engine damage, and the presence of coolant may indicate a coolant leak. By regularly checking the dipstick, you can detect these issues early on and take appropriate action.
Maintain Optimum Performance
Maintaining the correct oil level is crucial for optimum engine performance. Insufficient or contaminated oil can affect the lubrication and cooling of critical engine components. By regularly checking the oil dipstick, you can ensure that the oil level is within the optimum range, helping your engine run efficiently and prolonging its lifespan.
Stay Safe
Checking your oil dipstick is not just about maintaining your vehicle; it's also about safety. Insufficient or degraded oil can lead to engine malfunctions, which can be dangerous while driving. By regularly checking the oil level and condition, you can reduce the risk of unexpected breakdowns or engine failures, ensuring a safer driving experience for you and your passengers.

Use a UV light to locate the leak
Engine oil leaks are one of the most common automotive leaks. They usually occur at broken or worn gasket joints around the engine block. To locate an engine oil leak, you can use a UV light without adding any dye as the oil fluoresces just fine under UV light without dye added. It glows a nice iridescent light blue. You can also use a fluorescent dye that, when mixed with oils, becomes visible under specific UV light. This method is used to detect otherwise invisible leaks and provide unparalleled precision in problem localization.
One of the trusted names in automotive leak detection is Tracerline, which has been a leading name in the automotive leak detection market for more than half a century. Tracerline developed leak detection and perfected the engineering science behind fluorescent leak detection technology. More than 250 million vehicles worldwide have had Tracerline’s leak detection dyes installed.
To use a UV light to locate an oil leak, you will need to follow these steps:
- Clean the engine thoroughly.
- Run the engine briefly.
- Dust the engine with talcum powder. The talc will adhere to any exposed oil, and you can trace that back to the source of the leak.
- Use a UV light to inspect the engine in a dark environment. The oil will glow under the UV light, indicating the location of the leak.
It is important to note that when using UV lamps, you should avoid direct exposure of eyes and skin to UV light.

Oil dripping onto the driveway
There are several methods to remove oil stains from a driveway, ranging from household products to specialised cleaners. One common method is to use cat litter, baking soda, or dish soap to absorb the oil and then sweep or rinse it away. Another method is to scrub the stain with a stiff nylon brush and laundry detergent, then rinse with warm water. For tougher stains, a more potent cleaner specifically formulated for concrete or driveway surfaces may be necessary.
To prevent oil from dripping onto the driveway in the first place, some people suggest using a no-splash oil drain pan or an oil extractor. Placing the drain pan on a wood block to reduce the distance for the oil to travel can also help minimise splashes. Additionally, using a plastic tarp or a splatter pad underneath the car can catch any splashes and make cleanup easier.
It is important to remember that oil is flammable, so it is crucial to be diligent with cleaning up spills and properly discarding any materials that have been in contact with the oil.

Use a plastic tarp to catch splashes
Oil pans can drip oil, especially if the oil is hot and flowing fast. One way to prevent oil from dripping onto the floor is to use a plastic tarp to catch splashes. This method is useful when there isn't a lot of room to work with, such as when the car is on plastic ramps.
To use this method, slide a plastic tarp under the car before beginning the oil change. This will catch any splashes or drips during the process, protecting the floor underneath. The tarp also makes it easier to slide under the car to perform the oil change.
Using a plastic tarp is a simple and effective way to contain oil splashes and prevent a mess from spreading onto the floor. It is important to note that while the tarp catches the initial splashes, there may still be some cleanup required after the oil change.
In addition to plastic tarps, there are other products designed to catch and absorb oil drips and leaks, such as absorbent drip pans and pads. These products typically have multiple layers, including an absorbent core that traps oil and an impermeable backing that prevents it from reaching the ground or floor. They are designed to be rolled or folded for easy storage and can be used under machinery, vehicles, or equipment during maintenance or repairs.
