You have not given much info to go on but check turbo intercooler pipes if you have them, any leak will change the airflow mixture. They can get a bit oily inside and slip off too, happened to me and I thought I had blown the engine till I saw the pipe off. Secondly clean the mass airflow sensor unit, its the round tube thing near the air filter with a plug on it. Check the air filter is good. then look for any air leaks from the mass airflow sensor on wards.

Re: volvo s60 deisel blowing sotty smoke
There are a few things that can cause sooty smoke. Check the are filter and the turbo. If its the turbo then the exhaust pipe after the turbo will have oil in it. If you can give me more info I might be able to help more if this doesn't do it for you.

if its black smoke and id say it is being a deisel it can be injectors or just simply fuel pump timing. get it to a deisel specialist to check the pump timing and your fuel load under acceleration, only real way to get it sorted.
the head gaskets are blown you can believe that anytime on any engine gas or deisel that you get oil in the radiator and there water/ antifreeze in the oil pan the gaskets and or cylinder heads are bad
Before you do the next oil change,get a can of motor flush.
This is the inexpensive method the free up the rings and restore some of the compression.
Use Shell 15W40 oil
Do you know the history of your replacement engine?
When was the last timing belt change?
A loose timing chain and guide can cause injector timing problem.
Start monitoring the coolant level for protential head gasket leak.
To save time,I would do a high rpm (below REDLINE) highway ran to blow off all remaining diesel SOOT.
Let the shop to do a compression test.
DO NOT DO THIS YOURSELF.
The max psi is 1850 PSI
Stay away from biodiesel blend fuel until you figure out what's the cause of the problem.
Use Diesel Cleen silver bottle and see is there any improvement.
Add the recommend dose of SEAFOAM into the crankcase to soften the valve stem seal.
Leaky valve stem seal can introduce oil drop into the cyclinders over-night.
Mointor any oil lose from valve cover.
