Last summer, we took a long trip in our 1998 V70 and did not change
the oil before or after...To make a long story short, about a month
after we returned we noticed heavy smoking from the exhaust and were
told we had sludge in the engine...Our dealer scolded us for not being
more asiduous with oil changes, flushed out the engine and sent us on
our way.

It is important to note that the engine is about 4 years younger than
the car due to an accident that caused us to need to replace it.
Similarly, the turbo went shortly thereafter, so the turbo is also
around 3 years old.

Since then (78,000 miles) we have changed the oil about every 3
months. We had the smoke problem again at 104,000 miles and again had
the engine flushed by the dealer.

The car now has 120,000 miles (the engine about 60,000) and we
started having very severe smoke issues. We tried having the engine
flushed again. albeit at a quick lube not the dealer...but to no
avail. We took it to the dealer who said that we need to replace both
the engine (with a used engine) AND the turbo...close to $7000! He
said that he might be able to just replace the turbo, but the concern
is since the engine is so sludged up, and has a few oil leaks, a new
turbo might "blow it out"... Is there really no way to clean out
the engine and simply replace the turbo (which will be the 2nd on the
car)...or is this just wishful thinking?

It depends on what's wrong. I've seen oil pans on these cars so full of
sludge that they have oil pressure problems. Once you've interrupted
the flow of oil, there's no telling what will fail, and usually very
quickly. My guess is that the oil pan should have been removed and
cleaned, but that's easy to say in hindsight.

Do you think it is too late to clean the oil pan? The car still
drives--albeit belching smoke (as long as I keep my foot off the
accelorator as much as possible when I drive it is manageable)

No doubt the Turbo will fail soon, though...

Actually in these cases there's doubt about everything. Removing and
cleaning the pan may fix everything, or possibly bearings are already
too far gone and it will be a waste of time.

This is what I'd do at this point:
Remove and clean the oil pan and oil pickup tube.
Remove and clean or replace (they may be too hard to clean) the oil
delivery and return lines for the turbo.
Replace the oil trap (aka PCV box) and hoses. (They are too hard to
clean.)
