The typical price range for a PCV valve on a Nissan Altima is about $5–$25 for aftermarket parts, or $15–$40 if you buy an OEM part from a dealer. If you add a hose or gasket in a kit, expect $20–$60. Prices vary by engine type and model year.
In this guide, we break down what affects the cost, where to shop, and how to verify compatibility for your specific Altima. We also cover roughly how to replace the valve yourself to save on labor.
What a PCV valve does and why price varies
The PCV (Positive Crankcase Ventilation) valve helps regulate crankcase pressure and directs unburned gasses back into the intake. Different Altima generations use slightly different PCV valve designs depending on engine type (for example, four-cylinder 2.5L vs. V6 3.5L), so prices can vary by part number and year. Always verify the exact part number for your engine to ensure a correct fit.
Price ranges by source
Prices differ based on whether you buy aftermarket or OEM, and whether you purchase the valve alone or as part of a kit with hoses and gaskets.
- Aftermarket PCV valve (non-OEM): typically $5–$25 depending on brand and quality.
- OEM Nissan PCV valve (dealer): typically $15–$40, with variations by engine and year.
- PCV valve kit (valve plus hose and/or gasket): $20–$60, offering a more complete replacement package.
When shopping, expect the widest variation with older or newer model years and different engine configurations. Always check that the part number matches your Altima’s engine code (e.g., QR25DE or VQ37V?) and year.
Where to buy and how to verify compatibility
Choosing the right retailer and confirming compatibility are key to getting the right part at a fair price.
- Authorized Nissan dealers or NissanPartsDeal online store for OEM replacements.
- Auto parts chains (AutoZone, Advance Auto Parts, O'Reilly) for aftermarket valves and kits.
- Online marketplaces (Amazon, eBay) with options ranging from aftermarket to OEM; read seller notes and verify part numbers.
- Salvage yards or used parts are generally not recommended for PCV valves due to reliability concerns.
Always confirm your Altima’s engine code and year, and match the part number to avoid incompatibilities. If in doubt, ask the parts counter with your VIN or engine code to ensure a proper fit.
DIY replacement basics
Replacing a PCV valve is usually straightforward and inexpensive. Here’s a quick guide to help you decide whether to DIY or have a shop handle it.
- Locate the PCV valve on the engine valve cover and follow the hose to the intake tract.
- Detach the hose clamp or clip and remove the old valve from its grommet or port.
- Install the new PCV valve, ensuring it seats firmly and reconnect the hose securely.
- Start the engine and check for vacuum leaks or rough idle; reset any related monitors if needed.
If you replace only the valve and notice the hose is aged or cracked, consider replacing the hose or the full kit to prevent future leaks.
Summary
For a Nissan Altima, expect the PCV valve price to range from roughly $5 to $25 for aftermarket parts and $15 to $40 for OEM dealer parts. Kits with hoses or gaskets can run $20 to $60. Prices vary by engine type and model year, so always confirm the exact part number and compatibility before purchasing. DIY replacement is typically quick and economical, with most jobs completed in under an hour for a competent DIYer.
