I recently noticed a coolant leak and after ruling out a bunch of thing initially thought it was the coolant drain bolt in the engine but after replacing it, the issue persisted. So I took a bunch of stuff apart and found pretty conclusively that coolant is coming through the engine wall itself. Head gasket or cracked block or something else?

If it's an 8thgen (06-11), those had cracked block issues, predominantly in, I think, 06-08 model years. I think some 09s were affected, too.
