So what's the difference between them fixing the engine they sent you and giving you a different one. To fix the compression ratio, they will have to replace the pistons, which entails pretty much an entire rebuild of the engine. Shame on them for shipping an engine in that condition in the first place, but you didn't even give them the chance to fix it.

They DO make good pistons, but it seems CHP/Probe has some quality control issues with thier engine builds.
