As you know, there are many different places in your motor that are sealed by gaskets. I would suggest narrowing this down by placing a piece of cardboard underneath the vehicle when parking it at night to test for a couple of things. Number one, does it leak when the motor is not running or otherwise under pressure and two, approximately where under the vehicle does the leak come from. Gaskets can fail over time due to excessive heat and will eventually shrink causing them to fail and leak. I would recommend having an expert from YourMechanic come to your location to diagnose and repair your oil leak.

If your car has a burnt oil smell, this could indicate an oil leak or low oil level. Check the level with a dipstick and look for leaks around the area. If your oil level is low, schedule an oil change as soon as possible. If you suspect a leak, head straight to a mechanic.
If you begin to smell burning oil, then this is probably an oil leak that is starting to leak on other components in your engine. This is not a smell that you`ll want to ignore hoping it`ll go away. This oil leak can cause your engine to overheat and cause other serious problems, too!
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.
A burning rubber smell means that a hose or belt has somehow gotten loose or broken and is touching something hot, resulting in it either burning or melting. Either way, it can cause issues – melted hoses can cause leaks, and melted belts can do major damage to your engine.
If your engine smells of burning or smoke, there are two possible reasons for this: it`s overheating or there`s a problem with the oil. Generally if it`s overheating, you`ll know about it because a warning light should appear on the dashboard.
If you`re just driving along and you notice a potent oil smell, it`s a sign that you may need to schedule an oil change. If you don`t change your oil in the immediate future, this oil smell will get stronger in your cabin. This smell will also become more potent outside your vehicle.

Types of Toyota vehicles having oil defects

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.
Phantosmia refers to any smell you detect that isn`t actually there. For some people, these odors are pleasant, like freshly baked sweets. But most people describe unpleasant smells, such as: Burning rubber.
Most of the time, this is the first indication that the timing belt is failing. The timing belt needs to be checked to see if it is going bad.
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.
Over time, engines can develop small oil leaks that would otherwise go undetected. However, if the oil leak forms somewhere high in the engine, and the oil drips down onto a hot component like the exhaust pipe and burn there, you`ll detect an unpleasant smouldering smell in the cabin.
If you`ve got a bad clutch, the signs will be anything but subtle. The smell of a clutch gone wrong is potent. It might smell similar to burning brakes, but has been described as a sickly, heavy stench. Some people have related it to sulphur or gun smoke.
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.
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.
Motor Honey is an oil treatment that you add to your car`s regular motor oil. It`s designed to reduce oil burning (and the smoke that it sometimes causes) without having to make any changes to the engine itself. All you have to do is include one bottle with each oil change.
White vinegar cuts through odors naturally. Try wiping down furniture, washable walls, floors, etc. with white vinegar. Also, try placing several bowls of vinegar around the room with the smoke damage, leaving them there for several days.
Because of wear, vehicles are more likely to consume engine oil as they age. Burning oil is a common problem, but when it is ignored, it can do major damage to your car`s engine.
The problem: In certain Toyota cars and SUVs, the engine may consume excessive oil due to faulty pistons and piston rings.
If your car is burning oil, it`s probably wearing out. Over time, the piston rings have likely become worn or stuck in their grooves, preventing them from sealing tightly against the cylinder wall. The tiny gap that has formed between the ring and cylinder wall allows oil to enter the combustion chamber and burn.
Toyota recommends that you have your oil changed every 10,000 miles, but to continue with the 5,000-mile service intervals for fluid top offs, inspections, and tire rotations. Schedule a service appointment to get started or continue reading to learn more!
Boil a vinegar and water solution
Bring 1 cup of water and 1 tablespoon of vinegar to a boil in a small saucepan. Let it simmer for a few minutes. Some people add bay leaves, fresh rosemary, vanilla extract, lemon halves or peels, or cinnamon sticks to cut down the vinegar-smell (and add a pleasant natural odor).
