Thanks for the reply, David.

It's coming from the exhaust so it may be normal as you say.  When I first
got the bus it did the same thing but stopped after I had the valves worked
on.  Every since the long trip from Tx to Denver and back it's been doing
it again.  I'm not too worried about it but I thought it might be related
to the starting problems I'm having.  i.e. Not enough air when starting and
not enough air to burn all the fuel while it's running.
