Furthermore, how do you fix an engine that’s burning oil?
People also ask, why is my car burning oil but not leaking? 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.
Additionally, 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.
Also, why do Hyundai GDI engines burn oil? The short answer is that when they’re clean, GDI engines don’t burn any more oil than any other engines do. … But when those deposits slough or flake off, they can become lodged in the piston ring area, which does directly increase oil-burning.

What are the signs of worn piston rings?
- White or gray exhaust smoke.
- Excessive oil consumption.
- Low power for acceleration.
- Overall loss of power or poor performance.
How do I know if my piston rings are worn?
When drivers notice excessive oil consumption, white or gray exhaust smoke, poor acceleration, and/or overall loss of power or poor engine performance, they may be seeing signs of worn piston rings.
Can a blown head gasket cause oil consumption?

What are the signs of a bad PCV valve?
- Engine misfires at idle.
- Lean air-fuel mixture.
- Presence of engine oil in PCV valve or hose.
- Increased oil consumption.
- Hard engine start.
- Rough engine idle.
- Possibly black smoke.
- Oil fouled spark plugs.
