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
