11127645173 New PCV Valve Cover Repair Kit Valve Cap with Membrane B58 for BMW F20 F21 F22 F23 F30 F31 F34 F32 F33 F36 G30 X3

Fantastic! Cheapest and easiest engine repair ever.Did you get the SQEEEEEE and smoke in your BMW? Sounded expensive, right? This is probably what you need.The original plastic cap cracked during removal (common) so it's good this includes one. Your OEM spring is probably reuseable, but this includes one.Small and cheap enough to keep a spare in the toolbag.

Factory replacement way to expensive just goes to show how BMW exploits ownerson part prices. Still working no issues since install

Installed last year and has held up

Update: I had to buy another pcv valve kit from this seller because the first one failed before 3 months. Note that I was only able to change the membrane. This time I wanted to use the new pcv cap but the second one did not fit as well. This time the membrane had a side that was uneven and the seal moved everytime I tried to close the gap causing a leak.

Works, but definitely is cheaper quality than OEM.

This easily replaced the existing diaphragm. My 340xi suddenly started billowing white smoke. The existing diaphragm had a small slit in it. Sometimes you should go with more expensive original equipment parts but this isn’t a computer. It is a piece of rubber. I reused the original spring and plastic diaphragm support. I only used the cap and diaphragm from the kit. It works like new.

I was getting a very loud whistling from my engine and lots of white smoke from the exhaust. Turns out it was just the PCV valve, easy fix with this.

so far so good, it's been a month since i installed this thing...
