🔩 Ensun 11127570292 Engine Cylinder Head Valve Cover for N55 Engine 3.0L - High Quality and Exact Fit Review

Unfortunately it didn't work for me even though I installed it correctly. I had to replace the entire valve cover on my N55.

The product was good and fit properly, but it will not solve your PCV problems. This will improve the situation but not fix it.

Did absolutely nothing for my suction problem but left me with blue balls (waste of time, energy and another 4 days without my car)

This is an update. The part only lasted 3 days and is now making the same vacuum noise, plan to remove and return once I get a better quality replacement. Great fit 2011 535i

Eliminated my squeaking (probably from the main seals) after I installed it. But a word of warning, do your homework on this fix. It's not just a screwed-up detail. You have to cut the old one and paste the new one. I used a small hacksaw and JB weld. If you have a little skill, you can go from a $1,000 fix to a $40 fix. Although the search engine said it wasn't, it fits my 2011 X5 3.0 N55.

I used this on my BMW F10 N55. Use YouTube videos for instructions, it's not that hard to do. However, this did not solve my problem. I'm going to completely rebuild my valve cover. If you're buying this to relieve crankcase pressure or reduce squeaking, just note that there are 3 other non-serviceable diaphragms inside the valve cover. While this may solve your problem, it's possible that other bezels are bad too.
