2012 BMW 128i 3.0L Valve Cover Oil Leak & Misfire

This 2012 BMW 128i with KW Suspension & AFE Power upgrades arrived at our shop for diagnostics and repairs. With 52k miles, the valve cover and oil filter housing gaskets started to leak and needed to be replaced. The customer also stated that engine is misfiring but without the Check Engine indicator light on. We scanned the control module and found a fault code for a misfire in cylinder number 5. The customer approved to replace the coil and all 6 spark plugs which solved the issue.
