Which outcome occurs when uneven thermal expansion binds pistons?

A)Engine knock and cylinder damage
B)Increased valve float and misfires
C)Increased oil pressure, filter rupture
D)Alternator over-voltage, ECU failure

💡 Explanation

Engine knock results from piston seizing due to thermal gradients generating excessive friction between the skirts and cylinders, because the heat cannot dissipate adequately. Therefore, engine damage occurs, rather than electrical or oil-related issues, which are independent systems.
