I had to cut short a road trip yesterday because my 81 Vanagon has ejected
the #3 spark plug twice during my travels, which I replaced by the side of
the road with a new one each time.  I was able to tighten it down, or at
least so I thought.  I called my mechanic from the road after the second
occurrence and he assured me I could make it home safely and I did.

Now that I am home, I am looking for wisdom from the list.  My mechanic says
either I have stripped threads or a cracked head (horrors!), which is
heating up, expanding and letting go of the spark plug.  I won't be taking
the bus in until Monday, so any other thoughts, wisdom, advice and anything
you all think I can check out on my own will be appreciated.  I have a few
days off and time to tinker since I am no longer camping under the watchful
eye of Mt. Shasta :-(

Thanks!
