“Piston slap is generally caused when the cold running clearance (piston-to-wall clearance) is large enough that when the piston rocks from side to side in the bore it “slaps” the side of the cylinder and causes noise,” explains JE Pistons’ Clayton Stothers.

Will piston slap damage engine?
You can still drive with a piston slap, but it may be uncomfortable and annoying if you can hear that knocking noise from the engine. They may cause further damage to the engine in the long run, but it really isn't a big problem. We recommend paying attention to your car's exhaust gas.
Does piston slap go away?
It lessens with driving but the slapping sound is always there. The slapping was there when I bought the car with 120K miles on it, however it went away when the car warmed up. I put 30K miles on it before it cooked the head gasket.

Is piston slap harmful to engine?
They may cause further damage to the engine in the long run, but it really isn't a big problem. We recommend paying attention to your car's exhaust gas. A piston slap may wear down the piston rings more quickly, which can lead to an oil leak into the engine.
How do you fix piston slap?
Piston slap is caused by pistons hitting the side of the bores, and no amount of oil will fix that problem. However, if you just want to fix the noise issue, many people have said a thicker oil helps. Make sure to get a high-end, thick-as-honey oil, and it should help stop the knocking noise on start-up.
How is piston slap reduced?
The allowable travel distance of the piston before hitting the wall: smaller skirt-to-bore clearance can reduce the piston slap noise. For example, lower liner temperature decreases the clearance by liner contraction. Higher piston temperature may reduce the clearance.

Will SeaFoam help piston slap?
Piston slap is the typical small block chevy noise. Sea foam is NOT what you want to use, at all, for anything. since that is not an option for most ppl, just let your car warm up for a minute or so. They the noise should go away.

Is there an additive for piston slap?
A Piston Slap Nugget of Wisdom: My only additive of recommendation is Seafoam. Seafoam seems to fix everything…in motors with a lot of miles and a lot of carbon buildup.
