That would be a great help!...whenever it's an engine issue. Or when it's a failure of one of the parts of the engine.

Recent sounds I've tried to imitate have included "I got a bad tank of gas that was 20% water, and it's January in New England, and ice is pinging around," "I think my muffler has a leak," and "Maybe one of my wheel bearings is going bad?"

I drive a 17-year-old car with 225k miles on it because I don't want to drive anything made after the advent of smartphones, so I get to make lots of funny noises. The muffler one and the wheel bearing seem like they should have been findable!
