🔧 GM Genuine Parts 12575660 PCV Hose: Superior Crank Ventilation Solution Review

I was hesitant to purchase this product, but I'm glad I did. As a result of my tests, I determined that the ventilation system is highly effective and reliable. The installation process was straightforward and the product has held up well over time. The only downside is that it can be a bit pricey compared to other options on the market. Overall, I would recommend this ventilation system to anyone in need of a reliable replacement part.

Nothing to say. This is a hose. It fits perfectly. This hose comes in a pretty tight spot. Bottom line, connect the upper part of the hose first (put it on, without the clamp), then attach the lower end, grasp with the tip of the needle and loosen the clamp. The clamp comes into a "locked" open mode and is loosened and tightened after a light push with pliers. (the clip has a small notch that holds it in the open position)

Arrived on time. Working on the valve cover on my Pioneer 04 4.2. Perfect size and fit to replace my old part. Comes with a pre-installed clip, ready to attach. If you have an inline 6 replacing this part, the old one will likely fall apart if you pull on it. Pcv leaks will wreak havoc on the fuel mixture resulting in a strong odor in the exhaust and the idle will suck.
