BMW sell an extended helicoil for the job but you need a jig to do it properly. A standard helicoil will block the oilway so you need some proper advice from an expert - Get in touch with Steve Scriminger at www.scriminger.co.uk
Dan at Cycleworks sells a jig for this repair. I'm not suggesting you buy one but the info on his site helps you understand what you're up against http://www.cycleworks.net/index.php?main_page=product_info&cPath=29_33_51&products_id=21

Dan at Cycleworks is a top bloke to deal with. If you need any special tools he's the man to see www.cycleworks.net

Dan will hire the rigs, and he has two set ups , one for a standard helicoil, and another for a larger timesert insert which replaces a pulled helicoil.
Top bloke, as Rob says.

I have done these before and not used a Gig, if your careful ?you may not need one but you do need the specific coil whick has a couple of its treads kinked at one point to pass oil etc,There red in colour...
Use a wurth timesert and then drill out the hole where the oil way is located
