Crankcases and PCV Valves
Basically, a crankcase is the casing for the crankshaft of an internal combustion engine. Combustion produces pressure within the crankcase. Positive crankcase ventilation (PCV) valves regulate the vapor pressure within the engine and recycle it back into the engine.

Not sure if 1995 is like 1994, but on my 1994 MPV 6cyl (3.0L), the PCV is in the middle of a hose on the BACK of the engine, UNDER the throttle body assembly. Took me a LONG time to find it!

Where is the PCV valve located on a 2002 Ford F-150 4.2L V6 was told that there is'nt one?
I was told the same thing....There IS a pcv valve and it can only be purchased from the dealer. Go to the normal spot for a pcv valve (passenger side valve cover near the firewall) There will be a hose connected there, follow that hose to where it connects at the other end. That is the pcv valve. it also has two smaller coolant lines attached and is held in with two screws.

Are all car engines have a positive crankcase ventilation valve?
So far as I know. It was the very first (about 1971) and still the most basic anti-pollution device. It is also the easiest to replace (takes 30 seconds in most vehicles), and the easiest to "fix". Remove the PCV valve, give it a good shot of spray carburetor cleaner, and shake it. If you hear a rattle when you shake it, it's fine - put it back, you don't need to replace it yet.
A few vehicles, Jeep 4.0L inline 6 for example, use a fixed size orifice instead of a PCV valve.

The above answer is WRONG!!! The PCV valve is located near the catalitic converter on the backside of the motor. Changing it can be a tough if you don't know what you're doing. refer to a shop manual for more info.
It is wrong. I've been trying to figure this out for a while with all the different suggestions on the web. I was about to remove the heat shield and started feeling around for the valve. Standing at the front of the car, there is an opening toward the right side of the heat shield. You can feel a hose going behind it. follow the hose and the PCV valve is at the end of it. It's a tight fit but it can be done. Just pull off the hose and then pull out the valve.

Where is the PCV valve on a 1987 300zx non turbo?
The PCV valve is located on the passenger side of the vehicle about center of the air collector system cover. It's right on top and easy to see and replace. Just remove the hose connected to it and screw the valve out of the intake manifold. Install is the reverse. You may want to check the valve first before replacing it. To do this, just remove the ventilation hose attached it and start the engine. If you hear a hissing sound coming from the valve while the engine is running, the valve is good. Also, if you place your finger over the mouth of the valve you should feel a strong vaccum pull. That would also signify a working valve.

you need to get knew rings the gas is going to the botem end try that You could have leaky needle valve in the carb. The float could have a hole in it and gas leaking into the float causing the float to drop too low in the bowl and allowing too much gas into the system. Mis adjusted float.
