Is this possible? is there a video? how-to? help???
Yes, it’s possible. Many people use magic loop knitting for socks.
Can you be more specific? Are you having trouble with the actual turning of the heel directions? Or working your mind around doing it with magic loop? Did you already do the heel flap?
I haven’t gotten that far yet, i wanna make sure i have a clear understanding of it before i get there…
it all becomes more clear, when you let us know what kind of a heel you want to turn.
I know, a sock heel 
But really: there are many different ways to turn a heel. And they are all interesting! I basically work by 2 methods and they both work fine. I am currently enlarging my knowledge as I have started with Wendy D. Johnson’s book about toe up socks.
These days I really prefer the bumerang heel. That works with short rows and is explained in many different patterns with many different little specs about it.
That for example is a heel that can be turned by magic loop knitting without any adjustments (except for ignoring the rest of the sock on the cable for a while.)
I bet it is this way with most heel variations: ususally you work the heel stitches only for a little while and just ignore the other stitches that rest on the cable.
That brings the following consequence: Put the heel stitches (all the ones you need) on one side and all other stitches on the other side of your magic loop set-up. Then just work by instruction.
omg! I’m also using a Wendy Johnson (aka Wendy Knits) pattern!!
