Pushed down on lower/left side of intake manifold and motor Moves???

...like the title says..when i pull the top of the motor towards me(front of car), there isnt really any movement, its when i push down on the lower left side of the intake manifold that the motor moves...im thinking maybe its one of the upper motor mounts, probably the back one...any other ideas?...i tried lookin for the mount to see if the screw or anything is loose or broke, im gonna try again with a flashlight...thanks for any info/help... http://****************.com/smile/emthup.gif
