Firstly, Helicoils used correctly every time. I've used them for years in all sorts of applications and they do exactly what they designed to do. Re-Coil kits are not expensive and you only, really, need five sizes at most to treat most things on a Seven. However, after that (and I'm sure I might get the wrath of some) but I don't use the traditional sump set screws any more. 1/4" BSW double ended studs, Loctited into the crankcase (with Helicoils if needed), steel washers and a 1/4" BSW Nyloc nuts are now my method of choice. Coupled with a silicone sump gasket, leaks from the sump area are a now thing of the past and the sump is easily removable (although why you'd want to is a subject for another thread 
) and re-fitted.
