�I'll repeat.The upper 8 mm stud hole is OK. The bottom broke off, the PO drilled it offset with about a 7 mm. Your suggestion is to thread with red locktite an aluminum bolt, cut the head off, then drill and retap with a 8 mm in the correct location. 
Or bring to someone who can Tig weld the hole , then drill and tap that.
I know a local machine shop who advertises they weld aluminum heads, but this is the block. That can be done also? Do WBX cases have magnesium like the older air cooled ?

Stuff I don't know because I've been driving a inline-four 13 years with a cast iron block.
Thanks for your suggestions.

Here's a thought -- clear out the old mess and drill/tap oversize,
thread aluminum rod to fit, install with red (stud-and-bearing)
Loctite and cut off flush.� Then drill/tap to correct size and
location and install stud.

Or open it out and have a welder build it back up with weld metal?

Did you actually mean 7/16?� That's 11+ mm.� 5/16 is almost exactly 8
mm (7.9375), though of course the thread is different.� If it really
is 7/16, how about fill it with 7/16 threaded aluminum rod Loctited
in as above, then clean out the remains of the old stud and proceed,
with a Heli-coil or similar if necessary.
