Why would I be getting oil in my air filter?
It is caused by excessive carbon deposits or engine sludge developing inside the crankcase. When the oil does not flow efficiently, excessive engine oil pressure will be created and cause extra oil to push through the PCV valve and into the air intake.
Why is there oil in my air filter on my motorcycle?
The most likely source is the crankcase ventilation system which will have a hose running from the crankcase to the airbox. Bad rings will cause excess crankcase pressure and could blow oil out the breather hose. The more common cause is an excessive amount of oil in the crankcase.
Why is there oil in my air filter box on my four wheeler?
Clogged Oil Passages Extremely clogged passages will cause pressure to build up and will open the opportunity for oil to push through the PCV valve and enter the air intake tube where it will drain into the air filter and filter housing.
What does oil in the intake mean?

Why is there oil in my air filter on my Harley Davidson?
Top breathing engines breath, or vent, through the top breather bolts which are threaded into the heads of a Harley Davidson motor. The air inside a motor is saturated with oil. It exits through the breather bolts and into the airbox where the air is filtered and the oil is captured in the air filter.
What does oil in intake mean?
Should there be oil in the throttle body?
A bit of oil in the throttle body is not going to harm your motor and is certainly not going to cause it to blow up. At an idle, the PCV valve restricts air flow, to reduce this problem. At high manifold vacuum (idle), a spring loaded valve is drawn up and partially restricts flow to the crankcase.
