The PCV valve on a 2008 Honda Accord is mounted on the engine’s valve cover and connected to the intake manifold by a vacuum hose. The exact spot depends on which engine you have: the 2.4L inline-4 and the 3.0L V6 share the same general principle but sit in slightly different places. In most cases you’ll find it with the engine cover removed.
PCV stands for positive crankcase ventilation. It helps recirculate blow-by gases back into the intake. In the 2008 Accord, the valve is typically located on the valve cover, and the hose runs to the intake manifold or throttle body. The following sections describe where to look for the two engine options available in 2008.

- Where to find: On the valve cover, usually on the passenger side toward the rear of the engine, near the firewall. A short vacuum hose runs from the valve to the intake manifold.
- How to access: You may need to remove the engine cover or some intake ducting to clearly see and reach the valve.
- What it looks like: A small black plastic (or metal) valve with a vacuum hose attached; sometimes there is a secondary small line from the valve cover.
- Replacement guidance: Use an OEM PCV valve; inspect nearby hoses for cracks or deterioration and replace if necessary.

3.0L V6
- Where to find: On the valve cover, typically toward the rear of the engine near the firewall on the V6 layout; a hose runs from the valve to the intake/plenum.
- How to access: Depending on trim, you may need to remove part of the air intake or other nearby components to clearly access the valve.
- What it looks like: A small black plastic valve with a vacuum hose; sometimes tucked under wiring or components near the valve cover.
- Replacement guidance: Use an OEM PCV valve and replace associated vacuum hoses if they show signs of wear.
For the 3.0L V6, the PCV valve is generally found on the valve cover toward the rear of the engine, near the firewall, with a hose that leads to the intake manifold.
Summary
The PCV valve in a 2008 Honda Accord is located on the valve cover and is tied into the intake manifold by a vacuum hose. The exact position varies by engine: the 2.4L I-4 places it on the passenger-side rear of the valve cover, while the 3.0L V6 typically places it on the rear portion of the valve cover near the firewall.
