Abstract
A valve stem seal assembly adapted for a reciprocable valve stem disposed within a valve guide can tolerate major variations in the guide height. The assembly includes a lower hollow cylindrical shell and an upper hollow cylindrical shell, both disposed about the valve guide. The upper hollow cylindrical shell is capable of being telescopically received within the lower hollow cylindrical shell in a slip-fit relationship. A seal member is secured to the upper hollow cylindrical shell, the seal member extending radially inwardly so as to engage the reciprocable valve stem and extending axially downwardly so as to engage the valve guide.
