Can you fix an engine that burns oil?
As a seasoned auto service provider at Kevin's Autos, I often encounter vehicles with the common issue of burning oil. This problem can lead to significant engine damage if not addressed promptly. In this article, we will explore the causes of oil burning, the signs to look for, and the potential solutions to fix this issue effectively.
Understanding Oil Burning in Engines
Oil burning occurs when engine oil leaks into the combustion chamber and is burned along with the fuel. This can happen for several reasons, and understanding these causes is crucial for effective repair.
Common Causes of Oil Burning
- Worn Piston Rings: Over time, piston rings can wear out, allowing oil to seep into the combustion chamber.
- Valve Seal Failure: If the valve seals are damaged, oil can leak into the engine's cylinders.
- PCV Valve Issues: A malfunctioning Positive Crankcase Ventilation (PCV) valve can cause excessive pressure in the crankcase, leading to oil being pushed into the intake.
- Oil Leaks: External leaks can also contribute to oil burning, especially if oil drips onto hot engine components.
Signs Your Engine is Burning Oil
Identifying the symptoms of an engine that burns oil is essential for timely intervention. Here are some common signs:
- Excessive Exhaust Smoke: Blue smoke from the exhaust is a clear indicator of burning oil.
- Frequent Oil Changes: If you find yourself adding oil more often than usual, it may be a sign of oil burning.
- Oil Warning Light: An illuminated oil warning light on your dashboard can indicate low oil levels due to burning.
- Engine Performance Issues: A decrease in engine performance or unusual noises can also signal oil burning problems.
Can You Fix It?
The good news is that burning oil can often be fixed, depending on the underlying cause. Here are some potential solutions:
- Piston Ring Replacement: If worn piston rings are the culprit, replacing them can restore proper function.
- Valve Seal Replacement: Replacing faulty valve seals can prevent oil from leaking into the cylinders.
- PCV Valve Replacement: Fixing or replacing a malfunctioning PCV valve can help regulate oil flow and pressure.
- Regular Maintenance: Keeping up with regular oil changes and engine maintenance can prevent oil burning issues from developing.

Frequently Asked Questions
Does burning oil mean bad engine?
1> Engine Damage: Burning oil can be a sign of engine trouble, such as worn piston rings, valve seals, or gaskets. Continuous burning of oil can lead to increased wear and tear on engine components, potentially causing costly damage or even engine failure.
Do you need a new engine if it's burning oil?
If they are old and hard, they will allow oil to get by and into the combustion area. New engines WILL burn oil. This is simply because the rings haven't seated yet. You can expect a new engine to burn about a quart of oil the first couple of week or so of running, but that will taper-off from there.
