Cold white-out highway heat

[wep0520]

OK i posted before but got no helpfor brakes but lets try this one. I just purchased a 94 f350 cclb 4x4 with a 7.3 turbo for 1k. The truck runs great around town when its warmed up. I live 50 miles from work, on the highway the truck over heats, the faster the hotter and around town temp is fine. When i start it in the morning, regardless of how warm or cold it is outside there is a white out for about 5 mins unless i fire and go. The smoke is obviously raw feul, its like sticking my nose in the tank. This is my first diesel so im not sure if its normal or not. Also there is is strong diesel smell for a couple hours after turning the truck off. Please any help, is this normal or what might be wrong?

No this is not normal ..... the truck doesn't have a miss does it ? .... also it might be a stuck open injector if this is the case you might be able to hear a knock or this might be a timing issue .... the injection cycle might be taking place way too late and might need to be retarded as far as the over heating issue make sure your thermostat is functioning properly and that your water pump is working properly also check your fan these trucks can run around town and not heat up with any of these components out but usually can't handle highway situations so check these parts out

It does have a ramdom miss at lights but havnt heard any loud knocks. I have no idea how to adjust timing. gonna have to get a book. I drained some coolant and it may be my radiator, gunk in tubes
