I hate to pour gasoline onto the bonfire that is rod bearing hysteria, but my car had the exact same 'knocking' noise is the video quoted above. It could be reproduced 100% of the time by accelerating hard from 2nd or 3rd gear with the engine off-idle (aka bog the engine). the knock/ping sound would start at around 2800rpm and disappear by 3500 rpm. It first happened in September during a trip to San Francisco. I thought it was the crappy CA 91 octane gas. When i arrived home in Seattle i filled up with my normal Shell 92, but the sounds persisted. After several bad Blackstone labs reports, I had my rod bearings replaced last week and since then ( last week ) i have not been able to reproduce the noise since.. strange, eh?
