I’m not quite sure I’d know, either. My Tacoma that I’ve put 270,000 miles on? You can bet I’d be able to hear a frog fart under the hood while driving down the freeway. But I’ve never heard this engine run, and like Rusty said, I’ve never broken in an engine.
Someday I hope to have the experience to be able to do it by ear, and I tip my hat to the folks here that do have that experience. That’s what makes FABO so great.
