My sort-a-new 1986 Vanagon is overheating.  After heating up, steam
forms from the left side of the motor.  It steams up, but I don't see
where its coming from.  No water leaking that I can see.  Does this
sound like the dreaded head gasket situation?  Can I changed them my
self in a weekend?   I am mechanically inclined.  Any info would be
gratefully appreciated.

Thanks,
