Where is the pcv valve on volvo s60 2.0T 2002

The PCV ( Positive Crankcase Ventilator ) valve is located in a valve cover. It is identifiable by the largish hose ( usually about 1/2 - 3/4 inch diameter )going from it to the intake system. If you have a throttle body injection system, the PCV hose will go to the throttle body. Typically PCVs are on the passenger side of the motor.

How to replace AUDI (VW) PCV valve

PCV is an acronym for positive crankcase ventilation.
The PCV Valve is a very common replacement item on many engines today. It's called the PCV valve for short but it stands for Positive Crankcase Ventilation. When your engine spins it many times collects pressure in the crankcase area, and it has to escape to relieve pressure on the motors bearings and seals. The PCV valve and PCV system is typically located near the intake manifold, and many times comes right off of the valve cover. It is very simple to replace the PCV valve, and you can do so by simply unscrewing it, and screwing in the new valve. We recommend using a little bit of teflon tape or paste to make sure you do not get any oil leaks.
Example (see picture below): 2,4 ltr. Audi V6 engine (BDV, AMM)

Oil suddenly blew out of motor.

Could be the PCV system, valve or whatever. If crankcase pressure builds up from defective pcv system, that could be the problem.

Where is the pcv filter located on a 2003 Silverado 5.3 liter? how do I replace the original filter?

The PCV valve is located on top of the Valve Cover, it is held in place by a rubber grommet and has a vacuum hose connected to it. The PCV valve can be easier to remove if you just pull the vacuum hose (with the valve attached) straight out and then remove the valve from the vacuum hose. Here is a picture of the PCV valve for easier identification.
A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.
