When should Pistons be replaced?

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.

What are signs of bad valve seals?

Here are some symptoms of a bad valve seal that may need to be replaced:Performing the Cold Engine Test.
