What happens if the oil separator fails in a Boxster?
In the most extreme cases, the air-oil separator fails to separate the oil from the air, and oil is then sucked into the intake manifold. Oil in the intake system is not healthy for the engine and it can foul spark plugs and destroy catalytic converters at the very least.
Where is the oil separator on a car?
You can also see the on the lower edge the AOS base on the engine and the two threaded holes for the securing bolts. With the AOS out of the way it’s a good time to clean some of the oil that may have leaked onto the top of the engine if the bellows was cracked or just from the rubber sleeves on the intake plenums.
What happens when the air oil separator fails?
When the separator fails, you will begin to see a large increase in the overall vacuum in the engine crankcase. In the most extreme cases, the air-oil separator fails to separate the oil from the air, and oil is then sucked into the intake manifold.
Why does the Porsche Boxster engine squeal when running?
The oil cap may be very difficult to remove when the engine is running due to high vacuum levels. In addition, you may hear a high-pitched squeal from the engine when it’s running: this is caused by air being sucked in past the crankcase seal due to the extreme vacuum inside the case.

What do you need to know about po420 or po430?
PO420 or PO430 CODE CATALYTIC CONVERTER FAILURE DIAGNOSTICS Following is a list of procedures that should be accomplished before the final determination that a new catalytic converter is needed. These are known as diagnostic procedures and go far beyond someone just performing a simple code reading and then declaring a bad converter is present.
What does the code po431 mean on a catalytic converter?
All that code says is either Converter operating below efficency or Converter operating below threshold. Nowhere in the interpretation of that code does it say the converter is bad. Your vehicle may very well need a Catalytic Converter but to determine this, your mechanic or technician should perform proper engine diagnostics.
