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.
What does a crankcase breather do?
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.

You have oil leaking out of your air filter on your Briggs and stratton engine?
the valves or rings are allowing compression blow by to enter the crankcase which causes excess pressure that is brought to the carburetor by the breather tube. your engine is getting tired or you have too much oil in the crankcase.
Why does 1984 ford 300 6 cylinder create vacum in valve cover?
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.

Why would I smell oil in a passat 2000 when I the car lows down?
If you have a 1.8T, the breather for the crankcase is below the intake manifold. The poor design of the engine causes oil to be sucked up through the breather and sit in the breather assembly then causing it to rot and fail. When you aredriving slow, the vapors from your crankcase waft in through the cabin air intake. you need to purchase a breather T fitting, it is expensive -about 45 dollars from the dealer, and install it. Look below the intake on the drivers side of the engine for the faulty part.

Why is there oil coming out of the throttle body on a 1989 Chevy s10?
The oil is probably coming in through the crankcase breather tube and into the air breather assembly. You either have a faulty PCV system or a very tired engine with "blowby".
