Hi - I listened your video and although I was able to hear the noise it was difficult to compare (maybe I will try to record mine) but I noticed yours is way more constant that the one I experience; the rattle on my engine lasts at most 1-2 secs under load and goes away - sometimes is not even there

Coincidentially, my rattle came back (and is Winter time as the last time.....maybe it has something to do with it -- --) - I removed the plastic engine cover (the vanity one) to check for loose stuff with no luck so far.....
