Due to the extended forces placed on race engines, regular refreshes are strongly recommended. We will be able to tell you how often we recommend them for different makes and specifications.
During our refresh process, the engine will be stripped down to individual components, every component will then be assessed, identifying damaged or worn components which will need to be replaced before reassembly. During re-assembly crank will be plasti-guaged, to check clearances and the correct shells will be selected. Cylinders will be honed, to allow proper break-in of new piston rings.
Valve seats will be re-faced and valves will be lapped where applicable. Valve clearances will be checked and re-shinned where applicable.
