valve clearance is the clearance between the valve puck and rocker its necessary for 2 reasons, the valve needs to be completely closed during firing and to make complete combustion and the exh needs to be open at the right time to let exhaust escape. improper valve clearance will cause a multitude of issues like misfire or fuel not burning properly
