Question about 1999 Chevrolet Venture
It`s very easy, follow the air filter / air inlet pipe (black,rubber about 4`` wide on the driver`s side) it goes to the throtlle body housing where your gas cable and cruise control is located. From this black inlet pipe you will see another black plastic tube that goes directly on top of the front valve-cover gasket (front of engine) Pull this tube which is angled and you will have your pcv valve plugged into this plastic tube. Purchase the pcv valve first so you can see the size and diameter of where this tube actually will fit.
good-luck, if you cannot locate the pcv valve then I suggest to wait for your next oil change where you can ask your repair shop for the location of the pcv, and or they can replace it. Usually there`s no charge for labour it`s very easy on this engine..

SOURCE: PCV valve for 2004 Hona CRV
PCV Valve Operation:
A vacuum-controlled metering device that regulates the flow of crankcase fumes in the positive crankcase ventilation system by allowing more flow at high speed than at low speed, and acts as a system shutoff in case of engine backfire to prevent an explosion in the crankcase.
Depending on your engine size, the PCV is a different style and slightly different location.
Usually they are mounted in a hole on your valve cover.... connected by a vacuum tube.
Some are mounted with threads into the engine block (usually by the oil filter)
On the '04 Crv - it is nearly inaccessible behind the AC compressor and beneath what looks like an old vacuum advance. Most PCV valves today do not need to be replaced, unless there is actual valve failure, which I have not seen happen. I would not be concerned about replacing it.
Thanks for using FixYa - a FixYa rating is appreciated!!
