Bushido... I figure you are refering to the mounting bolts... these need to be tight. The bottom four bolts shoulf have a sheet metal steel bar that has it's corners bent into the bolt heads. These bent corners act as bolt retainers - they keep these bolts from vibrating out.
You would need to bend them away from the bolt head to get a wrench (9/16" IIRC) on them to either tighten or remove. Bend these tabs back against the bolt head when you are done.
When I remove the engine and transmission I take photos with my smartphone of each bolt, wire, whatever I take off. This way I can view the pictures and use them as reminders on how to re-install the engine-trans.
