[QUOTE="FurryHungarian, post: 1057348, member: 21503"] Direct injection only engines obviously do not flow gas over the intake valves. The low pressure port injection will flow gas through the valves and allow the detergents to keep the intake valves clean on the new EcoBoost engines. Several manufacturers are switching to both direct injection and port injection for this reason (it also allows them to be more flexible with fuel economy when they control direct vs. port injection). This is a well documented issue with Volkswagen Group engines. Intake valve cleaning is a common practice in the VW world and just a fact of life. Suggesting the replacement of the heads due to dirty valves is just crazy. Sent from my iPad using Tapatalk Pro [/QUOTE]
