Review on 🔧 N52 Engine Valve Cover Kit for 2007-2013 BMW E70 E82 E88 E90 E91 328i 328xi 528i 528xi X3 X5 Z4 3.0L N51 - Includes Oil Cap, Gaskets, Spark Plug Seals & Bolts - Part# 11127552281 by Frank Villanueva

Pros: Fits well. I had to use a pry bar to align some of the screws. As someone said the thread is coarse and 8.6Nm doesn't even screw in. I tightened them with a 1/4" ratchet. Bad: Car was hard to start the first time. I ignored him thinking he was just getting used to things. Next time he blew out a puff of smoke, stuttered and then calmed down. I drove about 10 moles and the CEL light came on. Code said I'm getting skinny. Checked for vacuum leaks, nothing out of the ordinary except for the large vacuum you feel when you remove the oil filler cap. Tomorrow afternoon I'm going to dump the thing and use the gaskets on the old cap Hopefully this fixes the initial oil leak and terrible engine performance.
