Engine oil is imaginary to be contained inside the engine. As of time to time oil seals or gaskets may leak due to excessive wear and tear or contact to extreme heat. The oil leak will deal out oil outside of the engine and usually onto other engine mechanism that are very hot. while this occur, a burning oil smell will happen. However, what is not usually known is that burning oil can also be cause by internal engine components that are spoiled. If the leak is not correctly diagnosed or repaired, or the internal engine issue is not resolved, additional oil will leak or be consumed, which may create a potentially dangerous situation. There are a few things you should be aware of that will help you recognize an oil leak, and what you should do to resolve this problem before it creates serious engine damage or a dangerous situation.
Piston Rings Don't Seal:

The pistons in your engine move up and down in their cylinders. Oil control rings, often just called piston rings, allow oil to lubricate the cylinder walls and moving parts without pushing up into the combustion chamber. If the piston rings are stuck, worn, or broken, oil can get into the burning chamber and flame.

Valve Guides Leak:

Valves control the air-fuel mixture intake and the exhaust gas release. Valve guide stop engine oil from leaking into the combustion chamber from the top where oil lubricates the valve guides. If valve guides are worn, oil gets keen on the cylinder and burn.

What Are symbols that an Engine is Burning Oil?

The most common symptom that your engine is burning oil is a puff of bluish smoke from the tailpipe. The blue tinge is characteristic of burning oil. On a few cars, particularly those that use synthetic engine oil, the tailpipe smoke might not be so obvious. A burning oil smell is still quite obvious, though. It's off-putting and heavy, and could turn your stomach. Even without blue smoke or a burning oil smell, you could have a car burning oil but not leaking. Oil consumption is a normal part of engine operation, with normal oil consumption averaging up to a quart per 2,000 miles. It can leave your crankcase low on oil. If your oil consumption is much higher than normal, you might not know it until it's too late.

What happen to a Car if the Burning Oil Issue is unnoticed?

Your vehicle can run for a while if it's burning oil, as long as you keep addition engine oil when it gets low. There are, though, issues that will come up.

1. The engine will run rough, because oil doesn't burn properly in the cylinders.

2. Spark plugs will become fouled by oil, turning on the Check Engine light.

3. Excessive oil in the exhaust can cause your catalytic converter to overheat or fail.

4. Low engine oil can cause a blown motor or seized engine.
