I'm trying to remove the main crankshaft bolt (engine still in place) but unable to budge it. Two questions ,do I rotate left to right or right to left, secondly , any easy way to recover a rocker cover but that's dropped done the engine beside the timing chain. All help would be much appreciated.

When you tighten its normally x torque plus x degrees .not as complex as seems.

You need to find a way to lock the crankshaft. The bolt is FT (a little more than fairly tight) - I seem to recall 275NM plus 90 degrees!).
It's normal right hand thread so righty tighty, lefty loosey.

As for the dropped nut a magnet on a stick would be my first tool to reach for - something like this:
