Where is the PCV valve on a 1993 Nissan Sentra?
PCV VALVE - Under hood, center, upper engine area, mounted in intake manifold
Answer It doesn't have a PCV valve. Actually it does. The PCV valve for a 1993 Nissan Altima is located behind the engine below the intake. Buy a Haynes manual, the PCV is VERY tough to get too but it can be done. You can only get two bolts from the top but have to go from underneath the car to detach the hose.
Hello, On a 2005 Nissan Sentra, the PCV valve is part of the crankshaft ventilation system. It's where the smaller tubing off the inlet air duct (top right) enters the valve cover. For an illustration of its precise location, it is Part Code 11810 in the diagram listed under the "Related Links and Sources" portion of this answer. Hope this helps!
To make it easier it might be better to remove the Breather Seperator first then unscrew the pcv valve from the breather seperator in hand. The pcv valve is located underneath and you can acces it by removing the oil filter and the oil filter base (4 nuts).I am having trouble finding a mechanic who can change this pcv part. They all want to charge 275.00 labor for a 8 dollar part!
