Replacing valve cover gasket on N55 - DIY

Bimmercode tutorial is spot on. Digital speedo is the first thing everyone codes on their F30. Takes 2 minutes and makes a big difference.

Did this on my 335i last month. The hardest part is removing the intake manifold to access the valve cover bolts. Make sure to torque the valve cover bolts to spec (8 Nm) in the correct sequence - start from the center and work outward. Over-torquing will crack the plastic valve cover. Also replace the eccentric shaft sensor seal while youre in there - its a common oil leak point and costs only 15 EUR for the seal.
