I'm new to the forum, Hi, Howdy, How ya'll doin. I just purchased a 1988 F250 7.3IDI with an alleged 68K on the clock. It was not running when I bought, finally got it running but I have a white smoke issue. The truck has been sitting for a while with the occasional (yearly) trip to the dump, it has had no fuel put into it for approximately 5 to 6 years. To get it started I dropped both fuel tanks and emptied out the old fuel, fixed both pickup tubes and the rear gauge rheostat, replaced the fuel filter, replaced all the battery clamps(all four were cracked), replaced the starter with a gear reduction unit, replaced glow plugs with motorcraft units. Fuel was reddish brown out of both tanks. I have never seen diesel turn brown or smell like old turpentine/mineral spirits. I did fill the filter with atf to get it started but I don't think the fuel would turn brown from so little atf. after sitting it was hard to start so replaced the lift pump, changed out the new fuel filter to a motorcraft filter replaced the fuel return system with the advanced kit from Conestoga Diesel. I still have white smoke and it is still hard to start after sitting overnight but not as hard as before. It idles fine with no missing but misses when the rpms are increased. It smokes at idle and when driven, more smoking when accelerating and when letting off to coast. I looking for suggestions/ideas before I invest in a new IP or injectors.
