Hey,
So I recently bought a 2001 v4 accord ex 5spd. I noticed a noise from the engine when I accelerate usually starts around 2300-2700 rpm 1/4-1/2 the time i start from neutral to first. It is sometimes quieter or not there in 2nd and can't really hear if it happens in third or higher. The noise doesn't happen when I'm in neutral. The noise gets louder as the rpm go up. The closest noise i can find is this video . I just changed oil with mobile1 10w30, lucas and engine restorer and no luck. Does anyone have any ideas? Can't really capture a good sound with my camera of the noise, but i'll try to find a way.

Thanks for reading/helping
