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 Mike Palma

The good news is that it's the same dimensions as a standard rocker cover and is barely visible when installed. I assume the built in oil cap is different. The bad part is that the gasket is a little loose on the valve cover, making it difficult to align once installed. The bead of a good gasket maker held it in place. The ugly part, the parts are screws. You are terrible. Carving is rough and imprecise, and it takes a lot of torque to get going. Because installation requires a very small but precise torque measured with a torque wrench, the threads make it impossible to install the valve cover to specifications. I tightened the screws within reasonable limits, let them relax overnight and did it again. That was a month ago, no problems so far.
