Oil Consumption
Excessive consumption of oil can be caused by a rupture in the head gasket. Oil consumption can be caused by other things (like worn piston rings) but if your car is going through too much oil, a blown head gasket could be the culprit.
Can a bad PCV valve cause oil burning?
The PCV valve serves the purpose of releasing combustion gases in a controlled manner from the crankcase of the engine; but as PCV valves age, they get clogged up and begin to suck oil along with crankcase gas into the engine, and consequently much of your vehicle's oil burns off.
Why is my car burning oil so fast?
Burning oil is often the result of worn out parts. For example, worn valve seals and/or piston rings could lead to your car burning oil. Both valve seals and piston rings work to keep engine oil out of the combustion chamber.
Can a bad PCV valve cause excessive oil consumption?
A clogged hose or PCV system or inoperative valve can increase oil consumption because pressure builds when the vapors in the crankcase aren't allowed to flow into the combustion chambers. That additional pressure can force oil past seals and gaskets.
Why do high mileage cars burn oil?
Reduced oil consumption: High mileage vehicles tend to leak and burn off more oil than younger cars due to degraded engine seals. High mileage oil rejuvenates degraded seals, which leads to less oil consumption and burnoff.
