Review: When my ’13 Chevy Malibu started idling rough and felt sluggish under light load, I figured it was time to swap the PCV valve. I opted for the genuine GM Parts 12642631 Positive Crankcase Ventilation valve, and I’m glad I did—it was a straightforward upgrade that brought my engine back to life. Installing it took just a few minutes: I popped the hood, pulled the old valve out of its grommet, and pressed the new one in—nice and snug, just like the factory part. No wiggling or force needed, and it sealed right away. I didn’t even need special tools; a flathead to pop the hose clip was all it took. Close to 200 miles later, I’ve noticed smoother idling, steadier vacuum readings, and peppy response when I ease on the gas. No hesitation, no rough chugs—just a calm, idle hum like a car that’s well-maintained. The valve itself feels rugged—sturdy plastic with those little guard ribs on top that keep dust and grit out. Comes labeled with the GM part number, so there’s no second-guessing whether it’s the right piece. It’s a small part with a big payoff. If you’re experiencing rough idle, check engine light, or just powering through regular maintenance, this OEM-grade PCV valve slides in and does exactly what it should without complications. Easy install, perfect fit, and noticeable smoothness—this one’s a solid win.
