The PCV or positive crankcase ventlation valve does as it is named. It will remove harmful gases from the engine. Also, you can find breather caps on the valve covers, this also helps to remove and fumes from the crankcase or engine base.
Yes, all gases from the atmosphere are inhaled but oxygen is indispensable for the life.
The noun forms of the verb to breathe are breather, breath, and the gerund, breathing.The noun 'breather' is an abstract noun as a word for a short break in activity; a word for a concept.The noun 'breather' is a concrete noun as a word for a device that allows gas or liquid to pass to or from an enclosed area; a word for a physical device.The noun 'breath' is an abstract noun as a word for a sign, a hint, or a suggestion of something; a word for a concept.The noun 'breath' is a concrete noun as a word for the inhalation or exhalation of air from the lungs; a slight movement in the air; a word for a physical action.The noun 'breathing' is a concrete noun as a word for the process of taking air into and expelling it from the lungs; a word for a physical action.
The oil is coming from the breather tube that comes from the valve cover. There is supposed to be a filter that will block this, but alas, they sometimes do not work to well. One way to stop this, if it is a big problem would be to put a little batch of steel wool in the breather line at the air box side. This might help. Or, replace the original line and filter. As long as there is not too much oil getting in there, the car will still run fine.
If you mean what I think, it is a tube that will connect to the air filter housing coming from the engine. It helps remove any combustable air build up form inside the engine. Simple terms of course.
Yes. They have lungs and air breather just like humans.
Allow pressurized gases to vent from the crankcase.
yes
The PCV valve is located in the camshaft cover,in the crankcase breather chamber or in the hose which connects the crankcase breather chamber to the intake manifold
on top of the valve cover
Too much crankcase pressure or the breather pipe is split/dosconnected. The crankcase breather goes into the rear of the air filter and the crankcase gasses are drawn in to the cylinder with the gas/air mixture and burned
the crankcase vents through the breather system.
No, the crankcase ventilation systems employed on diesels are not PCV (Positive Crankcase Ventilation) systems. They are CCV (Closed Crankcase Ventilation) systems. Diesels do not produce sufficient vacuum for a PCV system. They use only a crankcase breather which is vented to the filtered side of the intake ducting. The engine can "breathe" both in and out via the breather cap. The round black thing on the TDI valve cover is a breather cap.
Crankcase breather tube.
Its called a PCV Positive crankcase ventilation. Its the little gadget that plugs into the top of the valve cover. Pull it out and it will rattle. That means its good.
That should be the crankcase breather tube.
The engine should have a crankcase breather tube connected between the valve cover and the air cleaner. With the crankcase breather removed and a non-vented cap installed on the valve cover in its place, the PCV would create the vacuum you have.
The engine is getting worn and blow by is getting into the crankcase and forcing oil from the valve cover into the air breather.
