Valve clearance is the space allowed for the expansion of a valve actuation system. What valve clearance in millimeters would be needed for an engine with a 245mm long 1020 steel pushrod with an average oil temperature of 110 degrees C during operation? Ignore the rocker arm and valve stem contribution. The baseline temperature would be 20 degrees C.
