Not a good idea to put a jack under the oil pan

It was not me who did this, the cracks where evidently there when I bought the car three years ago. I hope no one is foolish enough to jack up the car using the engine sump... but some people suggest supporting the engine with a jack under the sump.

From the Pelican Parts site technical articles:
"Replacement of the mounts couldn't be easier... Gently place the floor jack under the engine sump, taking care to only apply enough pressure to relieve tension on the front mount... "

Note that this article does not even suggest using a block of wood between the jack and the sump.
