You won’t see any drips on the ground. When you find your car burning oil and not leaking, it’s not as simple as changing a gasket. The causes are much more severe.
When your motor starts to burn oil you better act fast. Odds are that your engine has some internal damage that will cost you a pretty penny to fix. In this article we’ll cover all the details about a motor thats burning so you can avoid overspending on engine repairs.
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 combustion chamber and burn.
Valves control the air-fuel mixture intake and the exhaust gas release. Valve guides prevent engine oil from leaking into the combustion chamber from the top where oil lubricates the valve guides. If valve guides are worn, oil gets into the cylinder and burns.
Cylinder head gaskets seal oil galleries in the engine block and head, allowing circulation without leaking oil or coolant inside or outside the engine. If the head gasket leaks, it can dump oil directly into the cylinders.
Engine pressure is released through a Positive Crankcase Ventilation valve, or PCV valve, back into the intake manifold. If this valve sticks, it creates engine pressure that can blow seals or push oil up into the cylinders.
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 some cars, especially those that use synthetic engine oil, the tailpipe smoke might not be so evident. 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.
Your car can run for a while if it’s burning oil, as long as you keep adding engine oil when it gets low. There are, however, issues that will come up.
The engine will run rough, because oil doesn’t burn properly in the cylinders.
Spark plugs will become fouled by oil, turning on the Check Engine light.
Excessive oil in the exhaust can cause your catalytic converter to overheat or fail.
Low engine oil can cause a blown motor or seized engine.
