Thevalve seal assembly is also preferably located near the end of the valve guide that isclosest to the combustion chamber. The valve seal assembly also includes a resilientsealing element that has an improved sealing lip for preventing the lubricating fluid fromtraveling past the sealing lip. The sealing lip is also positioned in order to extend theoperating life and effectiveness of the valve seal assembly.
