Why is my WELCH-ILMVAC Water Pump producing excessive oil mist?
- BBill RobinsonAug 5, 2025
Excessive oil mist in your WELCH-ILMVAC Water Pump can occur due to several reasons. Maintaining the oil level between the two lines on the oil window during operation is crucial. System leaks or degassing can also cause this issue, so locate and seal any vacuum leaks. Additionally, contaminants in the oil can contribute to the problem, so perform a forced oil flush if contamination is found. If you have an oil mist eliminator, check the element and replace it if it's saturated with oil. Consider installing an oil eliminator to coalesce the oil mist from the exhaust gases.
