I have a 94 F350. New glow plugs and new injectors with 230k miles. When starting it lots of white smoke but as I drive it the smoke goes away. Coolant smells like coolant, oil consistent with oil and the smell of the white is diesel smell. Rpms at 70 miles an hour is 2300. There seems to be no power loss, but the white smoke on start up and heavy at times concerns me. What else should I look for. Glow plug harness, fuel filter heater etc.....

thanks

 

what temp is it outside? trying plugging the truck in for an hour or two before you start it and see if that helps. it is normal to have some white smoke at start-up when the block is cold because the fuel isn't being completely burned until the engine warms up. If plugging it in doesn't help at all then i would double check your glow plugs, glow plug relay, and orings on your injectors. Also did you replace your valve cover gaskets when you did the glowplugs? if not I would suggest doing that too just to be safe.But my thinking is probably just need to warm up your engine with a block heater

 

IN Houston texas, temps not a problem. Once its running its fine, but I am leaning toward glow plug harness as we speak. All the glow plugs and injectors are brand new. No ring problems. Good rpms at 60 mph, 2000. thanks and if there are any other suggestions please send them my way.
