PCV on 1993 AltimaThe PCV valve on a 1993 Nissan Altima is located under the intake manifold just above the oil filter. You have easier access if the oil filter is removed. Not so easy...

Answer:

On the 2.4 liter the PCV is located at the passenger end under the intake manifold. It is located in a breather that has te be removed w/ 3 bolts. The PS pump has to be dimounted and pushed back on the loosened drive belt to move the hose back and you can access the bottom bolt. Use small needle nose or long reach 90 degree needle nose to remove clamp on pcv hose. Break the seal on the breather(use silicone to reassemble- black). Now you pull the breather and PCV out all together and reassemble the same way. Make sure to replace the grommet. Highly recommended due to hour or two this job takes.

Where is the PCV valve located on a 1993 Nissan Altima?

AnswerIt 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.
