LS1 piston slap or knock?
I went to look at an 02 Z28 today and it has higher miles on it. Does the LS1 slap/knock go away completely when it warms up or is there still a hint of it even after the engine warms up? It sounded a little more like a faint knock to me rather than piston slap so I'm a little leary. My old 93 would have some piston slap on occasion but it usually went away with an oil change. So should the noise go away or does it linger?
