What does piston slap sound like on a dirt bike?
On two-stroke engines, skirt wear can occasionally be heard audibly while the engine is running, which is commonly known as “piston slap”. A rhythmic metallic sound often accompanies a loose or worn piston when the engine idles. What can be heard is the piston rocking back and forth in its bore as it reciprocates.
Can I drive a car with piston slap?

When did the piston slap on a Chevelle go away?
I can remember my dad’s Chevelle SS had excessive oil consumption and piston slap.

The Chevelle made it to 100k before he traded it in.
How does carbon cleaner help with piston slap?
What is interesting is that carbon cleaner has been noted to help with piston slap. If that is true, then the piston rings on one or more pistons must be stuck in the ring land, not allowing the rings to properly support the piston in a cold running state.
