What is a crankcase air separator and an oil separator? What does the crankcase ventilation function do? What are the fault symptoms of crankcase ventilation system? What causes sediment formation beneath the oil filler caps?

What is the Role Of The Crankcase Ventilation System

It doesn’t matter what kind of vehicle you drive – petrol or diesel – it all has at least one form of Positive Crankcase Ventilation: (PCV) Positive Crankcase Valilation . This system’s purpose is to ensure that engine oil vapor and leaking gases are removed from the crankcase.

Unburned gases are the majority of the gases that leak into your crankcase. These leaks can increase depending on vehicle mileage and wear to engine parts. These gases can be harmful and should not be released into the atmosphere. The engine parts could be damaged if it is not done so. High pressure can also cause oil leakage from the gaskets or hoses due to high crankcase pressure. A ” Crankcase Ventilation Systems (PCV). It is necessary.

However, not all vehicles are equipped with a “Crankcase Air/Oil Separator” All of them work together in the same PCV system. This part is called something else in some cars or trucks.

What is Crankcase Air/Oil Separator?

Any engine’s lifeline is oil. Lubrication is essential for all parts of the engine. It is important to maintain a regular lubrication system in order to prevent wear.

Normal operation of the engine will allow the oil and air to mix. However, while the air is being sent to the combustion chamber and the oil is returned to the crankcase for recovery, This is done in conjunction with other breathing devices around the engine. Crankcase Air/Oil Separator Also known as the crankcase breather or valve.

What are the signs of crankcase air / oil separator failure?

Oil vapors may cause oil separators to become clogged and their efficiency can decrease. Engine failures can result from damage to internal parts or the complete breakdown of the oil separator. To ensure your engine’s longevity, a functioning PCV system will be crucial.

There will be signs of malfunction if the crankcase air or oil separator stops working.

Smoke coming from the exhaust, check engine light on and deposits under the oil cap are the most obvious signs of malfunction.

1- Take a puff from the Exhaust Pipe

 

The crankcase oil and air separator is used to separate oil and air inside the engine. This part can wear down and cause separation problems. It is difficult for the fuel/air mixture to burn cleanly and properly when there are additional gases introduced into the combustion chamber (acidic gas in the oil). The vehicle then emits more smoke from its exhaust system. Excessive exhaust fumes can be more apparent when the vehicle is at idle or accelerating.

You should immediately have your vehicle checked by a mechanic if you see white or light-colored smoke coming from the exhaust pipes. You can endanger cylinder bearings, pistons or rings by delaying the process.

2-Engine Check Fault Lamp

The temperature rises when oil and gas are mixed into the combustion chamber. This will cause your vehicle’s ECU to issue a warning and the check engine fault lamp to turn on. You should inspect the OBD2 scanner and make any necessary repairs.

3- Oil Warning Lamp / Excessive Oil Reduction

A faulty crankcase oil/air separator can lead to the engine using more oil than it should. The problem occurs when the engine consumes more oil than it needs. This problem is more common in engines that are higher. This is the main reason vehicles lose oil. This part should be checked if the oil warning light on your instrument panel is not working properly and you need to add oil frequently.

4- Sedimentation Under the Oil Cover

 

A faulty crankcase air/oil separator can lead to oil evaporation or condensation. These vapors can collect under the oil filler caps and form a film. If you experience this problem, take your vehicle in to a mechanic to have the oil separator checked.
