Question

Quizplus · Accepted Answer

Piston slap is a condition where there is excessive clearance between the piston and the cylinder wall, causing the piston to "slap" against the wall during operation. This typically produces a hollow, bell-like noise, most often occurring during cold engine warmup when the components have not yet expanded to their operating clearances.
