ACDelco Gold 19313320 Positive Crankcase Ventilation (PCV) Valve

Perfect fit in a 2001 Chevrolet corvette z06, definitely fixed my crankcase issues since the one I had before was the original from 2001, it was very easy to install but I have a custom setup for mine since I have performance parts in my engine bay

Good quality and fit

Works well and it's a good price.

Great OEM parts fits snug and performs great!!

OEM Replacement for my 2002 Chevy Suburban 1500 5.3L. just be careful taking the PCV hose off, they tend to be brittle. But once I got the hose off and the old PCV out, the new one slipped right in with no issues, fit perfectly. Extremely easy to install.

Good product. Works as it should . Fits right in place .

It's interesting that the Amazon description says that this is an aftermarket part. Clearly, it's OEM, ACDelco. This is the Pro model of PCV part number 12572717, which is discontinued and can't be found anywhere. This is the ball style valve which, if you have high oil consumption, may not be appropriate for your vehicle. I bought this as I recently noticed an oil film on my '02 Avalanche throttle body and valve covers did a search to see why. My 5.3 has, since new, continuously used oil. Always serviced at a GM dealership. Always told that my oil usage was "normal" for this engine. My recent search revealed that on 7/19/02, GM released TSB 01-06-01-029B which addresses high oil consumption for various '99 - '02 GM vehicles with 4.8 - 5.3 - 6.0 engines. I wish that I had been told this. The TSB calls for a fixed PCV valve (non-rattle) to correct this problem. That ACDelco part #CV4000C is also discontinued. If your vehicle needs the fixed valve PCV, call your local GM dealership parts department and have them do a dealer inventory search for either 12572717 or CV4000C. I was able to find two of the discontinued correct PCV valves at one small dealership. Interestingly, this GM dealer had the part listed under the original, discontinued part number, but my local GM dealer did a search on part CV4000C. If you try this, have them do a search both ways. This Pro PCV valve from Amazon would fit and work in my 5.3 but I'm not installing it. If you're not loosing oil, and your vehicle isn't listed in the TSB, this PCV valve should work fine. While your at it, consider replacing both PCV hoses as well. The hose available here at Amazon, while it's OEM ACDelco and fits perfectly, attaches to the passenger side of the manifold and is not the fat PCV hose that attaches to the PCV valve itself. Happy hunting! Changing the PCV valve should be a regular part of vehicle maintenance that, if ignored (like I did), can lead to oil leaks, poor engine performance, lower gas mileage and more. Your vehicle and wallet will thank you.

Perfect original fit and function for the 5.3 in my 2001 Suburban. Great value for a factory GM part.

O produto veio bem embalado, em perfeitas condições. Parece ter boa qualidade. Bom custo benefício

Compre esta pieza original para reemplazar la que tenia que era la generica, quedo y funciono perfecto tan solo al instalarla notas la diferencia de la calidad acdelco. Llego a tiempo, con su bolsa y cajita original. La pcv generica hacia un silvido como de perdida de vacio, pero conla pcv acdelco ya no presento ese extraño silvido. El scaner no marcaba ningun codigo, pero por inspeccion al motor logre diagnosticar que era la pcv, se instalo la pcv acdelco y listo. Gracias

يمكن وزنية الشركة بس أسيدلكو ثقة إن شاء الله

Acdelco are great automotive product and can always depend on it. Eazy to install and fix exact.

Im ersten Moment war der Fehler (Unterdruck auf der Kurbelgehäuseentlüftung) behoben was mich sehr gefreut hat. Das ging allerdings nur ca. 7 Monate gut. Jetzt ist das Ventil wieder ausgefallen..
