Hollow Engine Noise
Hollow Engine Noise
I'm getting this hollow engine noise when I'm accelerating in 1st and 2nd gears between 1500 - 3000 rpm. In the other gears it sounds fine, and the acceleration is fine. What could possibly be wrong?

Re: Hollow Engine Noise
it could just be your engine getting dragged down trying to match wheel speed. since 1-2 shifts are the biggest jump in RPMs, its most likely to happen there than anywhere else
Re: Hollow Engine Noise
But I never heard it before. It's more like a hollow whirring noise.

Re: Hollow Engine Noise
did it just occur suddenly? if thats the case then get it checked out. but if it doesn't sound like its hurting the engine, most likely its not

Heat shield? Belt tensioner on its way out? A bearing on one of the belt accessories?

even the dude @ the dealership didn't know what it was. I don't think it's a common problem

not good. vid of the sound?Caramel wrote:even the dude @ the dealership didn't know what it was. I don't think it's a common problem
Re: Hollow Engine Noise
I would get the vid, but it's kinda temperamental and the sound isn't very loud, it's just audible to be honest so I don't think it's going to come up through a vid. But i'll definitely put one up if the sound comes back soon.

Re: Hollow Engine Noise
probably a baffle rusted away inside the muffler
