If the "furnace guy" thought it may be a sludge issue originating at the
tank, did he bother to check the filter? Has anyone checked the filter? If
there is in fact sludge in the tank it will be in the filter also. Did
anyone check delivery pressure when they were standing there looking at
it,
for diagnostics sake? Most, not all, but most service providers are not
equiped or adequately trained to diagnose oil problems. Find a specialist,
guarantee he will find the problem.

Yes, I'm sorry, I forgot to mention that they did replace the filter at the
tank. It was pretty clogged up, but at the time when the filter was
replaced, that being December of 2004, I had only been in the house 6 months
and had no idea when the previous owner had the filter replaced. The repair
guy did not check the pressure though. I will make sure to keep that in mind
when I get someone out to look at it in the near term.

thanks for the advice...
