Another area of the valvetrain that operates under severe conditions is the valve springs. Proper valve spring pressure is essential for a racing engine to reach its maximum potential and to avoid costly valvetrain damage. This hand-held valve spring pressure tester is not as accurate as a bench model tester. That is not its purpose. It allows you to establish a baseline reading of the valve spring’s seat pressure. From this point of reference you can monitor the progressive wear of this critical component. It allows you to replace weak or failing valve springs, which can inhibit optimum performance or cause severe engine damage. This task is easily performed in a matter of minutes while the valve covers are already off and you are adjusting the valve lash. Please add this activity to your maintenance schedule.
