i don't think it will vent fumes to engine compartment cuz it can only vent if there's vaccum. now there's none. correct?

hey guys, my mileage was real bad cuz my evap system was full of pinholes so i disconnected the vac hose between the evap valve (right under the intercooler-TB hose) and the Tee that goes to the inlet manifold.

i've got some vibrations in the cabin whenever i drive off from a stop. i'm suspecting my top engine mount. no cracks, but its quite hard. not soft like my other rubber mounts. good or no good?
