Steve when I did my mounts, I was able to lift each side of the engine seperately by the bellhousing ( manual trani). As was reported, someone did crunch their oil pan because he was foolish enough to put the would under the buldge for the drain bolt. AND I suspect he jacked the engine until his bellhousing hit the firewall. The oil pan can't handle the weight of the whole front of the car.

The advantage to jacking from the bottom is that as you ease the motor back down onto the new mounts it's easy to see the engine mating with the mounts. If you do it from the top you can't see whether you are mating it properly.

Pick your poison.
