How to Deal with Engine Piston Slap?

[RubyRose]

When piston slap occurs mildly, the engine power becomes slightly unstable, the engine shakes severely, and it may cause the engine to overheat and emit black smoke. The solutions for engine piston slap are as follows: If there is a knocking sound when the engine starts and runs at low temperatures, but the sound disappears when the temperature normalizes, it can be temporarily ignored, and the engine can continue to run. If there is a noticeable knocking sound when the engine is at normal temperature, high-speed operation should be avoided as much as possible, and the engine should be disassembled for repair as soon as possible. If the cylinder is severely out-of-round or scratched, or if the gap between the piston and cylinder is too large, replacement is necessary. If the connecting rod is found to be deformed, it should be replaced if possible.
