<VV> Marble Sound

[FrankCB]

Jeff,
     Correct!  Back in the old days, I used to say it sounded like a bunch of empty Coke bottles (glass) rattling around back there, but that kinda dates me<GGGG>  I could easily make it happen just by failing to push the water injection button when I accelerated.  And that was on a non-turbo Corvair with the timing set where it was supposed to be.  It did burn a bit of oil, as I remember, so the water mist counteracted the lowering octane due to the engine oil in the combustion chamber.

Just a thought - a "marbles rattling in a can" sound is often pinging.
