Dash Rattle/Vibration GONE!
So I was having a very round plastic on something hard maybe metal, but it was coming from the dash right in front of me probably closer to where the bottom of the windscreen is. anyways I was dreading having to pull the dash. after banging around it seems forward most edge of the dash rattle a bit, I have engine mounts and right around 1000 rpms the resonance causes a vibration of the dash that's LOUD! anyways without pulling the dash problem solved! I took some 5/16" inner diameter PCV/crank case breather hose. $8 at auto zone and shoved it between the glass and the dash. 5 min later Voila! sound gone! the hose is not visible inside nor outside. Ideally the 5/16" ID hose is best used on the outer ends of the dash and perhaps something around 3/4"-1" Outer diameter for about 1.5ft section in the middle would be ideal. but for now problem solved
