Damaged Piston Rings Pistons rely on three rings to create a tight seal against the cylinder wall: the top compression ring, the second compression ring, and the oil control ring. Over time, these rubber or silicone components dry out, crack, and lose their elasticity.
Low Oil Level Warning: Understanding Oil Burning Causes
When you start the engine after a period of inactivity, such as overnight, the initial puff of smoke you see is usually oil burning off that has collected on the valve heads due to failed seals. Worn Valve Stem Seals Valve stem seals act as tiny gaskets positioned between the top of the valve stems and the cylinder head.
A scenario where the engine is burning oil and smoking heavily is often the result of neglect or harsh operating conditions. Engine Design and Oil Viscosity Not all engines are created equal, and some are simply more prone to burning oil than others.
Low Oil Level Warning: Damaged Piston Rings and Worn Valve Seals
The Core Culprits: Valves and Seals The vast majority of modern engines burn oil because the barrier between the combustion chamber and the moving parts has been compromised. If the PCV valve or hose becomes clogged with sludge and varnish, pressure builds up inside the crankcase.
