Ensun PCV Diaphragm Repair Kit with PCV Membrane Replaces 917-064

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)

Perfect fit for my 2013 audi a4. Dealers were charging more for this part but thanks to Amazon I was able to aquire it to bring my car back to New.

If you need a new spring this kit is not for you!!! The cover and the actual rubber diaphragm are good quality.

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.

The product was a direct fit replacement and for now my check engine light has not illuminated. Had a feel to it which only put the word “quality” in my mind. 10/10 would recommend if the P0106 code or any other MAP sensor codes continue to pop up for your VW as this is something which even mechanics overlook. Quick way to check is to see if there is engine oil on your MAP sensor when you remove it. If there is this is most likely the culprit. Make sure you clean out the hose connecting to it and the inside when swapping out the diaphragm.

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

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.

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.
