Volvo MD11 smokes at higher revs

Older Volvo MD11 starts fine and runs without smoking when throttled to near idle. When I run it slightly faster to say to normal crusing speed 4-5 knots it begin smoking heavily and appears to be emitting oil or diesel out of the exhaust. I back it off to slow rev near idle and the smoking stops and appears normal. Also idle fine and starts fine. Note We did have a rough winter and I did have to patch a small crack in the bottom of the engine block to stop a small water leak. I did this three months agom and everything has been running fine uptill about a week ago. Any suggestions would be greatly appreciated.

Thanks,

Mike
 
Remove and send your injectors for test.
When re-installing, have someone to check the injection timing of your engine.
The small Volvo diesels are famous for smoking and sensitive to both timing and injectors.
Even have the air filters cleaned out in kerosene or similar and check the valves.
