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.

Why is there oil in air box on mercury topaz 2.3 liter?

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.


What is a breather tube?

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.

Does a diesel engine have a positive crankshaft ventilation valve?

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.
