The tool shown produced a rather rough groove. Now I have never worked on an engine part like this but I would imagine that a carefully sized dremel like cutter could produce a more consistent groove depth with smoother edges.
I saw a groove like that on turbine generator set. The grove was cut by hand, and it had some grease nipples tapped into it at intervals. An RTV type material was pumped into the assembly( this was before silicone was big time) and there you had an o-ring type seal, simply elegant that it worked so well.
Not being high-tech in comparison, this method worked a treat for my washing machine tub DIY seal:

It's been operative and used every other day for over two months w/o any sign of leaking!
My (unproven) personal hypothesis for the groove is the rougher its inner surface, the better the bite gets for the sealant.
Thanks for all you guys pitching in, particularly Frank S & ToolMaker51 for leading me to this nice solution!
