My 10 valve has started to emit smoke into the engine bay.This comes from oil burning under the filler cap and burn from oil squirting onto the hot engine from under the rocker cover.My mechanic says that the engine is worn and should be replaced.I trust his integrity but his Volvo knowledge may be limited.The engine has 195k on the clock-not much for this model-and goes like a rocket.This causes me to doubt that there are compression problems.There may be other oil circulation issues.Any Ideas?

The PCV system is blocked.
Yes , he does not seem to have much knowledge at all by the way you described his diagnosis..........
Test this by putting a disposable glove over the dipstick tube and if it blows up like a balloon then the oil fumes breather system from the block and rocker cover is blocked , its normal for this age 850 to need this done and it will go for another 100,000k easily !! :-)
Isit using oil?
Where are you?
Berry Motor Group or Voldat In Melbourne if you need a good mechanic.
This is fairly easy to do yourself as well if you are game. Plenty of online pictures and videos.
