6.0 Smoking Blue at start up
Well I have read as many posts as I could find that concern the 6.0 and blue smoke. I have a puff of blue smoke (not whiteish blue). Took the truck to my local dealer yesterday and they called today and said it was all taken care of and I could pick it up. They replaced the egr valve and glow plug relay. I went to pick it up about three hours later and got a puff of blue smoke at the start. Went in and told my service advisor and he got the tech that did the work. The tech told me that it is normal to blow a puff of blue on start and is due to rich fuel mixture. As far as I'm concerned, if there is blue, oil is burning. Rich mixture is black smoke. My warrantee runs out on March 5th and I am getting concerned. I am in Ulster/Orange county NY. Anyone know of a good diesel dealer close by. My advisor told me to call him tomorrow afternoon as he will do some investigating into this problem with ford. I would just like to have a back up dealer if I don't get anywhere. BTW 2003 6.0 crew cab. Any advice?
Thanks
Thanks

My truck does the same thing, always has. Pretty much every 6.0 I've seen will puff a bit of blue on start up and until they are warmed up. Some days its a big cloud other days its not so big. Just slapped synthetic oil in er today so I'll see if it puffs in the morning or not and then I'll know if it is oil for me.

Put synthetic in her the past two oil changes and doesn't seem to change mine. I am thinking possibly a injector O ring. But my real problem is to get my dealer to do something before my warrantee runs out. I still say if there is blue smoke than there is a problem. It may take months to see it on the dip stick because of the quantity of oil in those engines.

yeah its normal, all diesels do this, all my tractors do it and so do my trucks, your tech is right about the rich mixture on cold start up. stick your nose down there and smell it! then after its warmed up good, smell it again. youll see what he means by rich mixture.
drive it like ya stole it.

yeah your right Tex, on start up mine will blow black smoke,and if not plugged in chug a bit. But i do see a bit off blue smoke when it idles up in warmup mode. and my tractors if not warmed up will blow a puff of blue smoke if im in a hurry and they are not totally warmed up.

Diesel is a light oil distillate. Like others have sad when cold, diesels will either blow a puff of blue smoke or smoke white for a while due to moisture in the exhaust system. Obviously diesel ignites in a diesel engine because of the intense heat created from the super high compressed air. When the engine is stone cold not all of the fuel is going to burn completely and your engine will be slightly louder when cold because of the dramatic temperature rise "AKA" Combustion and the colder air.
I would also think that maybe the Crankcase ventilation system contributes in that you get a SLIGHT build up of oily vapors primarily from shutdown at normal temperature when you have vapors still collecting in your intake system. Let them sit and collect over night or a few hours and maybe they contribute slightly.

[QUOTE=pullinair]John, I have tried the scientific approach, but sometimes you cannot lead the horse to water.[/QUOte
Strange scientific approach. Pullinair stated that it should either blow blue or white smoke. Well which one is it and why?
Seems to me that if I go to my dealer and say I want to look at a new truck and go start it in their lot that there will be no blue smoke. I would bet my last dollar on that.
So you can always lead a horse to water, you just can't make him drink.
