URO Parts 11127570292 Valve Cover Gasket Replacement for BMW E90 E92 E93 328i 335i - Durable Engine Seal for Oil Leak Prevention - Perfect for DIY Auto Repair & Maintenance

I was considering to withhold one star, but I decided it's not too important. Just watch the bolts. The original bolts require E10 (star) socket but in this URO one only inner bolts were E10 and for the rest I had to use E12 socket. The thread and diameter are fine, it's just the head sizes are off. At the end I used E12 for all of them because the 8.5Nm low torque is permitting this, but in general it isn't cool. Other than this - a very good product and fixed the issue I had on 155K miles with a whistling sound. The whole replacement job could be tedious, but I already took the cover off twice - once for the leaking gasket and 2nd time for the Valvetronic. At this point - it's pretty straightforward :)
