Valve seal removal apparatus comprising:
- a longitudinal body having a shaft extending substantially coaxially therefrom;
- a lever member pivotally attached proximal a first end of said longitudinal body;
- a first gripping means having a first gripping member located thereon;
- a second gripping means having a second gripping member located substantially opposed to said first gripping member, said second gripping means being pivotally attached proximal said first end of said longitudinal body, said lever being capable of operating said second gripping means such that said second gripping means is biased in a direction towards or away from said first gripping means;
- a stop member located along a length of said shaft;
- an impact member located slidably on said shaft for impacting said stop member.

In a tool for removing valve seals from a valve guide on a cylinder head, said tool including a gripping end for gripping a portion of a valve seal and a slide hammer for impacting a stop mechanism and imparting an axial force on a valve seal in order to remove the valve seal from a valve guide, the improvement comprising:
- a gripping means including at least one biasable member, said gripping means further including at least a first and second piercing member, said first and second piercing members located substantially opposite one another for frictionally gripping a portion of a valve seal;
- a first handle portion;
- a lever for multiplying an applied force pivotally connected proximal said first handle portion and further including a second handle portion, said lever being operable by said second handle portion in order to articulate said biasable member between at least a first and second position;
- a shaft extending from said first handle portion and including a stop mechanism located thereon;
- a slide hammer slidably located on said shaft for impacting said stop mechanism and imparting an axial force to said tool.
