In the early production run of the LS-series engine, some engines encountered abnormal amounts of 'piston slap' - a problem caused by too much clearance between the cylinder bore and the piston. [10] 'Piston Slap' sometimes sounds more like a knock or the sound of a diesel engine running, it is also typically worst when the engine is cold and lessens as the engine reaches operating temperature. The noise of 'Piston Slap' often is louder when listening for it below the oil pan.
