Default Piston Scratched - Exhaust side
Hi,

When pistons have scratch marks on them, its usually on the exhaust side. Why is this so?

I just had a race last weekend, my nova flash PT siezed. I thought the rod broke. But when I took the engine apart, the whole exhaust side of the piston was badly scratched. Why?
