Excessive oil leakage can cause engine damage and should be addressed promptly. Oil coming out of a car’s breather system is often a sign of a problem. When you see this, you should investigate the problem to prevent further engine damage.
While it is normal for some oil to leak through the breather system when it is in operation, too much oil escaping can clog the air filter and harm other engine components.
In this article, we’ll take a closer look at why oil might be coming out of the breather and what you can do to stop it.
By following these steps, you’ll be able to keep your engine running smoothly and avoid costly repairs.

What Causes Oil to Come out of a Valve Cover Breather
- Clogged or Faulty PCV Valve: Prevents proper ventilation of crankcase gases, leading to pressure buildup.
- Excessive Blow-By: Worn piston rings or cylinders allow combustion gases to enter the crankcase, increasing pressure.
- Overfilled Oil: Too much oil can overflow through the breather.
- Faulty Valve Cover Gasket: A damaged gasket can cause leaks.
- Dirty Breather Filter: Restricts airflow, leading to pressure accumulation in the crankcase.
These factors can force oil out of the breather.
Steps To Stop Oil Coming Out Of Valve Cover Breather
If oil is coming out of the valve cover breather, it may indicate excessive pressure or other issues in the engine.
Here are the steps to address it:
- Check the PCV Valve: A clogged or faulty PCV (Positive Crankcase Ventilation) valve can cause pressure buildup. Replace if necessary.
- Inspect the Breather: Clean or replace a dirty breather filter.
- Inspect the Valve Cover Gasket: A damaged gasket can lead to oil leaks.
- Check for Overfilled Oil: Ensure oil levels aren’t too high.
These steps help manage crankcase pressure and stop oil leaks.
Preventing Oil From Coming Out Of Valve Cover Breather
Preventing oil from coming out of a valve cover breather requires regular engine maintenance, choosing high-quality engine oil, avoiding overfilling the oil, and upgrading to a crankcase vacuum system.
Regular oil changes and keeping up with engine maintenance are essential to maintaining the longevity of an engine and preventing oil leaks.
Choosing a high-quality engine oil that matches the engine’s specifications is important. Overfilling the oil can also cause oil leaks, as can a faulty or damaged valve cover gasket. An upgrade to a crankcase vacuum system can help to reduce crankcase pressure and prevent oil from escaping through the valve cover breather.
Keeping up with engine maintenance and addressing any issues promptly can help to prevent oil leaks and keep engines running smoothly.
