Can pcv valve cause throddle like symptom on 1994 nissan altima

Pcv system is kind of nose of the engine.
If you clag your nose and try to run for couple miles you gonna have breating problems need more air . so positif crankcase ventilation is controls by spring calibrated valve which we call pcv is collects blow by gases(this gases still rich for oil and unburned fuel molekuls) when engine needs it pcv opens and retun this gases into intake manifold to help emisions and reburn this rich vapors . however this return vapors also bring extra oil rich sticky debris to throttle which can cause late responds and lost of power.
you should replace pcv valve fallow all small vacuum lines and inspect hoses for any crack or leak replace if necesary with same size emission prof hoses and clean your throttle body with throttle body cleaners with manufacty service information.

Donde queda el pcv valvula en el motor

The PCV valve on Altimas looks different than what has been common for years on most engines. The PCV valve is located at the drive belt side of the engine under the intake manifold and attached to the breather/separator. Access from above is very difficult; access the valve from underneath the vehicle. There is a short hose that connects to the breather/separator.

Remove the breather/separator and the hose. Then you can unscrew the PCV valve from the breather/separator for easy inspection and cleaning of each piece. Also inspect both passages where the separator and hose connect. Here is a picture of the valve after it is removed. The breather/separator is a small aluminum housing that will fit in your hand.

Obviously the PCV system is more difficult to service on Altima engines than the more familiar design on so many other engines. A restriction in the PCV system will increase crankcase pressure. This pressure inside your engine will push oil out where ever it can find a place to leak, including into the distributor.

Hope helps.

Where is the PVC valve located on a 2003 Nissan altima se 3.5

You may have to remove the cover from the top of the engine to access the PCV valve. One side of the PCV Valve screws into the Valve Cover, and the other side has a rubber hose connected to the air intake. It is located on the right side of the valve cover.
