Hello Sam:
The sound is like a deep-throated knocking...like
something is loose. It "keeps time" with the engine..
ie: it increases as rpm increases. When starting the
engine cold it takes 30 seconds or so to start making
the noise (ie: not immediate upon start) I have aux.
VDO oil temp and pressure gauges installed and their
readings are normal both when idling and at speed. The
van has normal power...seems to run fine other than
the noise. Coolant temp has remained normal.

I keep an eye on my gauges and an ear out for noises
whenever I drive the Vanagon. This noise appeared out
of nowhere from what I can tell, ie: no gradual
warning.

Any ideas on diagnosis are appreciated.
Thank
Kevin

    What are the sounds like?  Be more descriptive.
When do they happen,have they happened frequently, or
did you hear it once for a fewseconds when you started
the van and then shut it off?  (which is not abad idea
though)   Do you know what it sounds like when a
lifter hasleaked yet not filled back up?

This sounds ominous but isn't.  Maybe this is all you
have.  But, then,maybe not.

Answer to the list so others can read the description
of the sound andhelp you out.
