How to Stop Oil Coming Out of Valve Cover Breather
One common issue that many car owners face is oil coming out of the valve cover breather. This can be a frustrating problem as it can lead to a messy engine bay and potential damage to other engine components. However, there are several steps you can take to prevent oil from leaking out of the valve cover breather.
Firstly, check the PCV valve. A faulty or clogged PCV valve can cause pressure to build up in the engine, leading to oil leaks. Replace the PCV valve if necessary.
Next, inspect the valve cover gasket. Over time, the gasket can become worn or damaged, causing oil to seep out. Replace the valve cover gasket if it is no longer sealing properly.
Ensure that the breather cap is clean and unclogged. A blocked breather cap can cause pressure to build up, resulting in oil leaks. Clean the cap thoroughly or replace it if needed.
If the breather filter is dirty or clogged, it can also cause oil leaks. Clean or replace the breather filter regularly to prevent this issue.
Check the oil level in your engine. Overfilling the engine with oil can cause excess pressure, leading to leaks. Ensure the oil level is within the recommended range.
Inspect the engine for any signs of damage or wear. A damaged or worn-out engine can cause oil leaks. If you notice any issues, have them repaired promptly.
Finally, if you have tried all the above steps and oil is still coming out of the valve cover breather, it is recommended to consult a professional mechanic. They can diagnose the problem and provide a proper solution.
