LA Engine Lower Timing Gear and Seal Questions

What purpose is the felt washer doing between the damper and the front seal of the timing cover? The motor in my Duster was rebuilt and when the rebuilder assembled it put the felt washer inside timing cover. It made a little sense to reinstall it there to prevent any excess oil from hitting the oil seal. I know the slinger keeps the oil on timing chain and gear. The parts manual doesn't show that washer at all.
