Humming sound when accelerating / Possible boost leak?

[louis100396]

Been noticing this recently. It doesn't happen all the time but I've been hearing this noise when I'm pressing the gas. The pitch increases as the I accelerate. Another thing I noticed is that I'm not holding much boost in 2nd/3rd gear. I'm not sure if they have anything to do with each other. Anyone have any insight on this?

Humming noise(happens around 0:02, 0:10, and 0:30)


Small pull in 2nd


Small pull in 3rd


More videos of possible boost leak?


Appreciate any input.

Dude you gota be on it, get on the loud pedal and record your peak while on wot.

even on wot, the boost stays around 1-5 psi, its very inconsistent. Sometimes it can hold all the way through.

There are many threads on this topic. The most logical conclusion was that is it transmission whine (I don't know if I spelled that correctly). They said buzzing went away when changing to a better transmission oil, but this would void honda warranty since they only say to use Honda oil.

When you notice this. Check if your ac is on. If so, try turning it off.
