Please confirm that there is a hole.
You may still need a motor, but...
I don't know how often that happens, it seems more likely that
some other component blew, allowing oil to purge freely, causing
a condition like overheating to cause it to die.

Also, how many miles ? How many miles driven by you ?

My 300SD is leaking oil right now due to oil cooler line.
New lines are on the way.
