Evidently, the 2.2L engine on a 90's era Isuzu Rodeo is an interference engine.
What that means is when the timing belt breaks and it jumps time, the pistons come up and total the valves.
No, I haven't pulled the head. But, I'm betting that there is lots of damage in there. I had that same problem on an '80s era Ford Escort. That vehicle was new enough to rebuild, so we took it down. When we pulled the head, every valve was bent and three pistons were holed.
I've seen this dragon before, and it's a beasty beast. I don't know if that engine is worth rebuilding.
Here's the little bastard that wrecked the engine.
