|Ouch, sounds like someone blew a plug out at some point in that van's past
|and used a plug shim to get the new one in.  Usually just a temporary fix,
|but I had a friend who drove his for another 50k before addressing the
|replacement head.  Your options are:
|
|a) install a new shim with the new plug (this may be difficult and prone to
|failure)
|b) install a new aluminum head
|
|Smarter heads than I may have other suggestions.

|Subject: spark plug threads
|
|Hi All,
|
|So, I started to tune up my vanagon but replacing the spark plugs. I took
|the second plug out and out with the plug came the steel (?) thread that
|lined the spark plug hole.
|
|I can still see threads in the hole but now the plug just drops in the
|hole.
|
|What are my options? Pulling the head and getting it re-threaded?
|
|Cheers,
|Harry
