Follow these steps carefully
Scan the 2019-2024 Nissan Altima for codes and inspect oil consumption, crankcase pressure, vacuum leaks, hoses, and the valve-cover area. Confirm the replacement PCV valve, seal, engine, and access path by VIN before disassembly.
Park the 2019-2024 Nissan Altima on level ground, set the parking brake, switch the ignition off, and let the engine cool completely. Disconnect the negative battery cable only when the vehicle-specific service procedure calls for it.
Remove only the engine cover, intake duct, brackets, wheel liner, or shields needed to reach the 2019-2024 Nissan Altima PCV valve. Photograph hose routing and protect nearby connectors from tools and dirt.
Release the hose or quick connector without twisting the hose, then remove the valve with the correct socket or pliers. Capture any spacer or seal and inspect the port, threads, hose, and valve-cover grommet for cracks or sludge.
Compare the new valve with the old one, install a new seal or grommet where specified, and seat the 2019-2024 Nissan Altima PCV valve in the original direction. Start fasteners by hand and use the exact engine-specific torque; do not use thread sealant unless specified.
Reconnect the hose, clips, electrical connectors, intake parts, brackets, and shields. Confirm every lock is seated and that the hose is not kinked, pinched, chafing, or routed near a hot or moving component.
Start the 2019-2024 Nissan Altima, listen for a hissing vacuum leak, inspect the valve and hose for oil or air leaks, and scan for returning codes. Let the engine reach operating temperature and do not drive if idle quality worsens, a warning light returns, or a leak is present.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
