I hadn't thought of the test machine, and you can't forget that bang. But with that, you're within 3 or 4 feet. But I agree, it would be much louder. Still, the response of the ear is logrithmic, so it wouldn't sound as loud as it actually is, and the passengers are a little farther away. What I regret is that so often the passengers are not questioned with some respect for the information they might have-- here if those opposite the engine had heard only one bang, that would suggest that it was two nearly simultaneous bangs, but at opposite ends of the engine.
Rising oil temp: Today I discovered an explanation for this not mentioned here, that can occur without a broken pipe. I'll put up a post on this tomorrow.
