Regular expression in sublime

Regular expression in sublime

I have this thing where I usual have something like (but not always)
- 30 30: 0 4 58 E
and that must be
- 30 30
: 0 4 58 E
or, in another case
- 32 32
: 0 2 63 All
must remain as it is
- 32 32
: 0 2 63 All
So any : must always be on the next line. Is there an regex for fixing
every case of this (so that it only does this when the : isn't already on
a new line?
I'm using Sublime text as editor
