Well, every Mitsu engine I have tried to repair major mechanical on the engine has failed,(4 vehicles, many tries) so I guess it should come as no surprise. Really I was just waiting to brave the failure. I was pretty negative because.

1. Started initially very badly.
2. Never started flawlessly.
3. Check engine light and stuck cylinder miss code same side as swallowed butterfly parts.
4. Power was NEVER the same as it was before munching the buttlerfly parts, almost felt like a 156HP 3.0 honestly.

Obviously the butterflys did deeper damage, despite the fact there was no metal in the oil. Or were the heads screwed up? I know Clearwater over bored heads killed the Red Montero engine.
