Hope some one can help, my Nanni diesel engine when started appears ok and on running up to 2000 RPM is still ok, however above 2000 rpm the engine starts to emit white smoke and lose power, filters and injectors have been renewed. An interesting fact is if I start engine without sea water cooling to engine for a short time the engine runs ok, even when I run without gb clutched in. I now suspect Charge Air Cooler, any Idea,s

Best Regards
Mick
