When should I replace my Pistons?

According to many industry experts, if the pin bore is worn more than 0.002″, the piston should be replaced. Measure the piston at its gauge point with a micrometer to determine if it has worn significantly. In cases of extreme detonation or heat, the skirts could have collapsed which will show on the gauge.

Can you fix a broken piston?

Replacing the single piston – essentially stripping the engine down and rebuilding it (replacing any damaged parts along the way) is probably possible.. but it’s unlikely to be economically sensible. The “metal smacking against something” sounds are worrying..
