Engine Valve Cover 11127570292 PCV Valve Cap Membrane Repair Kit Fit for BMW N55 Engine 3.0L for X1, X3, X5, X6, xDrive 535i, 335i, 435i, and X6 640i for Cylinder Head Cover

Perfect for my 2009 Volvo xc90 Got the job done!

This little beauty stopped my oil leak. Great item, it snapped right into place. No hassles, very easy to install.

Perfect fit for my N55 engine (BMW X6 2015). Do not get rid of your old spring as this one does not come with one and you will have to reuse the old one.

Replaced item without damage to surrounding tube. Sealed it well, without clogging/blocking the inside rift. Fit like a charm. Easy work. HOWLING GOT LOUDER! The situation is worse with this cheap part, after a well done installation. Bought the whole valve cover to replace it after this disappointment. Wouldn't know unless I tried this method first 🤷

Worked as described. Didn’t have to use original cap like others stated. Just had to push a little hard to get it to snap on.

worked out great used a angle grinder and a sanding disc to grind it down to the valve cover

As advertised and serves the purpose

My check engine light came back on right after the car passed emissions. The part appears to be 'good enough'. Installation was easy.

This was a good fix. So many things I didn't know about my 2012 BMW 535i. Lots of YouTube videos about PCV replacement. Some truths some not. I changed my PCV, not because of poor engine performance, but because of the weird "seagull" squeal at idle that came and went. I thought it was a bad bearing in something. I saw a video on YouTube and it documented the noise exactly and traced it to crank seals sucking air past, due to incorrect PCV operation. Truth. Another video said vacuum sucking when removing oil cap is sign of bad PCV. Not Truth. A warm engine will have vacuum under oil cap with good PCV. My test concluded that a vacuum leak on the PCV nipple shows a bad PCV. Other test might be necessary to prove out the whole system bud this one caused me to order the repair kit. The new replacement PCV cap fits very tight after I carefully removed the old one. The YouTube videos are invaluable to explain this. After installing the new cap with some silicone sealant and a rubber mallet I waited 12 hours and tested the car. Perfect. No leaks and no "Seagull" noises. $25 fix instead of $250 valve cover. Very happy.

This is not even a part for any mini cooper. I can not click 0 starts or even 1 star for some reason. Absolutely useless part that in no way fits the cars in the discription. See the pics I added. The diaphram is an extra inch larger this is for a completely different car and not for a r56 mini cooper
