<VV> Further Problems - was Oil Issues

[J R Read]

I think you are at the point where you remove the head and take it to a 
machine shop.

Double inserts might work, but welding in new aluminum and tapping that will 
likely be a better fix.

Well, I'm sure it will come as no surprise to many/most on VV, but I'm 
learning
it more and more every day: This "restomod" hobby of ours is not for the 
faint
of heart. Just about the time I solve one problem, another, seemingly worse 
one
pops us. I got the RTV goop and got the valve cover on, and then discovered 
that
the reason a backfire when trying to start the car last week had "spit out" 
the
#2 spark plug was that the hole was so badly reamed out the insert couldn't
hold. So I did everything necessary to remove the turkey roaster so as to 
get at
the offending plug hole, coated the insert with "red" seal and then 
proceeded to
re-insert it, tapping it with the associated tool to "swell" the serrated
trailing edge. But guess what, the hole was SO bad, my taps drove the insert
straight on through and into the combustion chamber.


Thus the question, is there any reasonable expectancy that I can retrieve 
that
thing without removing the head? And regardless of how I get it out, what do 
I
do now about the wallowed out hole? Can I re-tap it and somehow use double
inserts? Is there a larger diameter spark plug that will work in it? Or do I
just bite the bullet and buy a new head?

It never rains but what it pours.
