2pcs Crankcase Vent Valve PCV Pressure Regulating Valve Covers for BMW 545i 2004-2005, 550i 2006-2010, 645Ci 2004-2005, 650i 2006-2010, 745i/Li 2002-2005, 750i/Li 2006-2008, X5 2004-2010

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

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

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.
