PCV System Malfunction The Positive Crankcase Ventilation (PCV) system is responsible for managing the blow-by gases—combustion byproducts that leak past the piston rings—and recirculating them back into the intake manifold. Diagnosis and Solutions When faced with the issue of oil burning, a systematic approach to diagnosis saves time and money.
How Piston Rings Damage Leads to Oil Burning
A stuck PCV valve is one of the most common and easily corrected causes of excessive oil consumption. Engine Design and Oil Viscosity Not all engines are created equal, and some are simply more prone to burning oil than others.
Understanding the intricate mechanics behind this problem is the first step toward preventing expensive repairs and ensuring your vehicle remains reliable for years to come. 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.
How Piston Rings Damage Leads to Oil Burning
Worn Valve Stem Seals Valve stem seals act as tiny gaskets positioned between the top of the valve stems and the cylinder head. Seeing blue smoke curling from beneath the hood or finding oil consumption rates that seem impossible is a scenario that terrifies any car owner.
