[alfa] Re:Help - stripped cam bearing stud

["Dean W. Cains" <dwc@xxxxxx>]

Hi Richard:

You might want to take a look at Mike Valant's site:

http://mev4474.home.texas.net/index.htm

Look at the "2L engine rebuild" page, and you'll see that Mike had the same 
trouble on a pair of cam bearing studs, but used a product called a 
"timesert", rather than a helicoil.  Not sure what the differences are, but 
if anyone knows which is better, it would be Mike.
