You had a very lucky escape, I'm pleased you got away with it, I really thought the worst.
I would still clean it all down and look closely for any cracks, and then keep an eye out for oil leaks when you get going again.
Hopefully that rubber part took the blow and protected the cases.
Have a look here when you get a minute..
