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 Ray Gist

Do not buy. I bought it because it was a fifth of the retail price but it broke after 4 months. Now I have to buy a new one and pay for the labor to replace it. When I replaced it I had to buy a new oil cap from the dealer as the one that came with the kit didn't have a gasket. I couldn't return it as I didn't find out until it was replaced and the car started. About a month later I smelled and saw burning oil from the left oil seal. I checked the cover and found it was cracked at the front corner and towards cylinder 3. Then it got worse. Somehow oil was now leaking out from under the Valvetronic actuator. I went further and now misfires in 1, 2 and 3 cylinders due to the accumulation of oil in the cylinders. Waste of money for cheap parts. Just spend more up front so you don't have to do it twice and hurt your head.
