Your car is more than just a mode of transportation; it’s an intricate machine that relies on a delicate balance of fluids and components to function smoothly. One of the most vital fluids is oil, responsible for lubricating moving parts, reducing friction, and regulating engine temperature. When your car starts “spitting out” oil, it’s a clear sign that something is amiss. This isn’t just an aesthetic issue; it’s a serious problem that can lead to significant damage and costly repairs if ignored. Understanding why your car is spitting out oil is crucial for maintaining its health and longevity.

Understanding the Problem: What Does “Spitting Out Oil” Mean?
“Spitting out oil” is a general term that can describe several different oil-related issues. It usually refers to the visible presence of oil leaking from your car, either as drops on the ground or as a plume of smoke from the exhaust.
The color of the oil can provide clues about the source of the problem. Fresh oil is typically golden or amber in color, while burnt oil appears darker, almost black.
Possible Causes of Oil Leakage
- Oil Leaks: This is the most common cause of oil spitting out. Leaks can occur from various parts of the engine, such as the oil pan, valve cover, oil filter, or crankshaft seal.
- Blow-by: This occurs when pressurized gases escape past the piston rings and enter the crankcase. The excess pressure can force oil out through the PCV valve or other ventilation systems.
- Faulty PCV Valve: The Positive Crankcase Ventilation (PCV) valve regulates pressure in the crankcase. If it’s malfunctioning, it can cause excessive pressure and lead to oil spitting out.
Identifying the Source of the Leak
Diagnosing the exact cause of oil spitting out requires a careful inspection. Here are some steps you can take:
1. Check Under the Hood
Look for any visible oil stains or drips on the engine block, oil pan, valve cover, or other components. Pay attention to the color and consistency of the oil.
2. Inspect the Oil Filter
Remove the oil filter and check for any signs of leakage or damage. A loose or leaking oil filter can cause oil to spill out.
3. Examine the PCV Valve
Locate the PCV valve and check for any blockages or damage. If the valve is clogged, it can restrict airflow and lead to oil spitting out.
4. Look for Other Signs of Trouble
Pay attention to any unusual noises, vibrations, or smoke coming from the engine. These could indicate a more serious problem. (See Also: Which Engine Oil Is Best for Honda Sp 125 Bs6? Top Picks Revealed)
