i was changing my oil pan gasket and there was 3 bolt when i remove the 3 bolts my engine drop bout 1inch or 2 down is that a motor mount???

 

Those Bolts go through the Oil Pan and hold up the Engine Mount. I bet you crapped your pants when the Engine tilted.

Use a jack with bundled rags on top of It and jack It up to It's respective slot allowing the Bolts to pass through. Fini! Good Luck.
