I dont know about that motor,hopefully somebody that does will answer.Old diesels smoked quite a bit.I ran a 961 Ford and it would smoke white smoke until it warmed up,but it was worn out.I have worked on motors that were like that.It takes a diesel a while to warm up.They kind of like to be a little hot,especially if they arent broke in yet.If it smokes that way after its warmed up good I would think its getting water in a cylinder somewhere.If its only white smoke when its cold it might be over fueling.Like I say I am not an expert on a 5000 Ford motor.I have worked on diesel motors that did that,and some times it could be fixed,sometimes it couldnt.Old type motor maybe did that,but it kind of sounds like its over fueling,motors if they are non turbo,non aftercooler,non air to air,smoke more than newer ones,if not that it might be seeping a little water in a cylinder while its cold.The way to tell that is take your finger,touch the inside of the exhaust pipe,touch your tongue,if it tastes sweet its antifreeze and not supposed to be in the exhaust pipe.Dont do that a lot because it doesnt leave your body and if you accumulate about a cup full of antifreeze you might die!Another way is the cylinder leaking water will be lots cleaner than the ones that arent,so if you pull the exhaust manifold,and look at the head,if one of the exhaust ports is clean and the rest are carbon covered you know where the leak is.Other ways are,black trails of carbon running down the outside of the muffler,pressure building up in the radiator,boiling antifreeze out of the radiator,water in the oil.If it sets a couple of days,loosen the drain plug on the oil pan,oil will float on water if its sets long enough,by loosening the plug if there is water in the oil,the water will go to the bottom of the pan and come out as water before the oil if the drain is lower than rest of the pan.While changing the timing helped it you think,Diesels now days have variable timing made into them to get better fuel mileage.Old ones like that are probably set to where they are supposed to work best under all conditions.Where you think it might be better now,if it gets real cold it might not start,or it might get hot if you work it hard,I dont know.Since changing the timing helps are you sure its timed right?It would have to be close or it wouldnt run maybe.Just giving you things to think about,I could be wrong.
