Review on Dorman 47057 HELP PCV Elbow by Nathan Vaughn

This product fits like the original and is easy to fit. Given that you should probably be replacing both knees and both rubber bushings at the same time, it would be nice if they came as a kit, but the kits I've seen online were significantly more expensive than buying all the parts. separately. The hardest part of replacing a knee is removing the old one without destroying it or dropping parts into the valve cover. Don't forget to swap out the bushings and tubing when replacing your knee as chances are they're all bad. or will be damaged if the old knee is removed.
