volks,

i think i am in trouble.  i got in the vanagon this afternoon and started
it for the first time in a week or so, and i hear a bit of a knock and i
notice a lot of water coming out of the exhaust.  i haven't really tried to
drive it like this.  i basically repositioned it in the drive, so i can
remove the LP tank for some rust removal.  i find it very hard to believe
that having the LP tank disconnect and remove would cause these symptoms,
but i am open to anything at this point.

what have i done?

thanks for your time.
