Why is my air filter full of oil?
Clogged Oil Passages. The final possible reason engine oil will find its way into the air intake system and eventually clog the air filter is due to clogged oil passages. It is caused by excessive carbon deposits or engine sludge developing inside the crankcase.
How does a dirty air filter cause a misfiring engine?
Misfiring Engine. Restricted air supply from a dirty air filter results in unburnt fuel exiting the engine in the form of soot residue. This soot accumulates on the spark plug, which in turn cannot deliver the necessary spark to combust the air-fuel mixture.
What happens to an engine when there is no air filter?
This happens during the engine’s intake stroke. Without an air filter in place, the engine may also be sucking dirt and debris in at the same time. This can cause damage to internal engine parts, such as valves, pistons and cylinder walls.
What happens if you install the wrong air filter?
Incorrect filter installation or installing the wrong filter can leave your engine open to dirt and debris. When the engine’s air intake is not completely covered by a filtering element, extensive damage can occur. Here are common examples: • Turbocharger damage: Air filters are particularly important to turbocharged engines.

What happens when an air filter is clogged?
When the air filter becomes clogged with debris, it can cause the engine’s fuel efficiency and power output to decrease. If oil is found inside the air filter, it can also significantly impact the engine’s performance.
Where is the air filter on an engine?
The air filter on most modern combustion engines is located inside an air intake housing, which is installed on the top of the engine.
How often should I change the oil filter in my car?
In this instance, sometimes changing the engine oil, filter, PCV valve, and replacing the dirty air filter is good enough. However, if clogged oil galleys are discovered, it is usually recommended to flush the engine oil and replace the oil filter at least twice within the first 1,000 miles to ensure the engine’s oil galleys are clear of debris.
