Took my time getting the old cover off. Use penetrating lubricant around the edges. Worry more about cracking the plastic on the valve cover than about breaking the plastic tabs on the PCV cap you'll be replacing. Once you get the clips on the top half of the cap loosened, the bottom ones should free easily. Mind the direction of the vent when you install the new PCV cap - the vent hole should be pointing down (To prevent debris from plugging the vent)

Seems to work fine. Like the others i re-used the oem spring, it was longer and stronger. Had no problem snapping the cover and diaphragm on straight. Hoping someone will shed light on a good way to break off the original cover. It was really tight and I could not wedge a screw driver under it without risk to the valve cover. The Dorman one had some bad reviews so i settled on this one but if this one fails I may try the RKX one next.

Installed it 12/2/18, used the OEM spring and did what another 2012 Jetta owner did and sealed the diaphragm to cap with RTV sealant (Old one sat snugly in a groove in the cap; some pressure needed to pull it out....RTV sealant may not be necessary if you firmly push diaphragm into groove. Anyway....) for well over a year now, the car exhibited a little jerking / hesitation when taking off, or rounding a curve and accelerating...had already changed plugs, coils, and did the OXSs recently....Problem continued.....(So far anyway) this appears to have cured the problem...took a few sharp turns, acceleration is smooth now....acceleration overall seems a bit smoother (or maybe I'm imagining it)....This $15 solution is an easy fix, and beats paying $100 (Amazon) or $200+ (dealer) for the full valve cover w/integral PCV valve.....Not getting any OBD codes (At least not yet; keep crossing my fingers).

Sadly I didn't take any pictures of it but I assure you this part fits! At least on my MKV Jetta 2.5. Part looked exactly like OEM and installs with 0 problem. Just make sure you push it on all the way and you should be set! The price is right with this one, my fellow Amazonians.

I have a 2011 VW Jetta with 230k miles on it. For several years, I drove it about 2,500 miles a month. While my Jetta has been extremely reliable, I've had to replace the PCV diaphragm about every 50k miles or so. I've typically used the Dorman 917-064 part and it's worked great. I purchased an Ensun version to see if it would save a few dollars. While the Ensun part looks very similar and does fit well, it did not function nearly as well as the Dorman part. (In fact, the engine ran worse with the Ensun part than it did with the worn out PCV diaphragm.) I've replaced the part a few times, so I'm very familiar with how to do it.

Installed properly but created a leak. It would have been easier and quicker to replace the entire PVC.
