Inlet and exhaust valves are precision engine components used for sealing the combustion chamber that controls the gas exchange process in internal combustion engines.  This seal is created between the valve and the valve seat.

Due to the constant opening and closing of the valves, the valve seats and the valves themselves can become worn on the sealing surface.  This will reduce the effectiveness of this seal which would cause combustion gasses to leak, which may lead to a loss of compression. 

If this were to happen instead of replacing the valve and valve seat we are able to resurface or cut them to recreate the perfect sealing surface.  After resurfacing valves and valve seats we then vacuum test them to confirm they are sealing correctly.

Using our modern valve and seat cutting equipment we are able to resurface valves and seats for a wide range of vehicle on the road.
