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.
Does oiled air filter damage engine?
Oiled filters will damage your engine’s MAF sensor. Dry filters are the only way to go. Dry filters let tons of dirt get through to damage your engine’s pistons and rings. The fact is that both types of filter will help improve fuel mileage and performance.

Why is my intake manifold full of oil?
Clogged Oil Passage When oil cannot pass freely through the passage, it gathers inside the top of the cylinder head. When the passage is totally blocked, the oil will go through the PCV valve and enter the air intake manifold.
Why would I have oil in my intake manifold?
In a turbocharged car, failure of the turbocharger oil seals will allow to pass into the intake stream (and likely the exhaust stream as well) and will then push an oily mist through the intake. you’ll have oil coated plumbing up to the throttle body and into the intake manifold.
Can you use wd40 as air filter oil?

Is it normal to have oil in 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.
What are the symptoms of a leaking intake manifold gasket?
Common signs include the engine constantly overheating, coolant leaking, engine misfires, and a decrease in power, acceleration, and fuel economy.
Why is there oil in my air filter box on my ATV?
Registered. Excess crankcase pressure will cause oil to push into the airbox via the vent tube. This can be caused from too much engine oil and/or prolonged full/high throttle use (I.E. Flying down a gravel road tapped for a few miles) Cold (freezing) temperatures will magnify this as well.
Is it normal to have oil in the intercooler pipe?
Q: Is it normal to have oil in the intercooler? Oil might get accumulated in the intercooler as your car covers more distance, but this is not a frequent occurrence. And most times, it is due to a leak from your car’s turbo oil seals, which causes a restriction.

Problem Description The intake manifold gaskets can develop external engine oil or coolant leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.
