Lots of flywheel seals get replaced and still leak. The primary reason is that the f/w has a groove worn in the seal hub, this being much more of a problem with wbx’s than it was with older VW boxers because they tend to be left in the vehicle for two or three... by Chris | Jan 23, 2019 | 2nd time around, Auto tech
