yeah, the only thing is that i can't do it because it'll
only make the sound while i'm driving.

it only does it when i'm revving through the gears, if i let off the gas and
let the RPM's drop, it won't do it. it seems to only be doing it around
the 3000 RPM range, at least, that's when i can only hear it. oil temp and
pressure readings seem to be normal.

it's killin me.
i'm scared to nail it. help me!
