Guys try this with your V10 powered truck. I park my truck in front of my barn and move it in the morning to get my tractor out or bring in a car or truck to work on. I only run the truck for the time it takes to back it up out of the way and turn it off. When I come back later in the day or night and start it up it blows blue smoke for 10 to 30 seconds the clears up. Ford is the only one that has changed the oil and all filter at 3000 miles. It uses about two quarts of oil during that time. Ford replaced the engine in 2001 for the same reason and it has done it since new. I bought it new. The truck is a 1999 F350 SDSC 4X4 short box and has only 86000 miles on it and the engine was replaced at 34000. The truck has not been modified at all. Winter time it is worse. I just put headers on it and runs great. Try this on your truck and see if it smokes also. Please post your findings here. Thanks guys. Ron
I've had mine (05 w/50K) do it from time to time. I've been chalking it up to unburnt fuel still in the cylinders after shut down. I haven't experienced any oil usage between changes with mine. This "problem" is not too uncommon as we've discussed it before. Maybe a search will yield more info to help you??
Its normal. My motor only has 11,000 miles on it and its always done the driveway thing. I've seen quite a few other posts making note of this as well.

Normal for the V10. There's nothing wrong with your engine, but there is something wrong with your startup procedure. Always allow the engine to warm-up to operating temps before shutting down. Like Monsta said, it seems to be unburned fuel, which is quite a bit when you think of 10 cylinders.
2 quarts of oil at 3000 miles is a little much, though. What gears do you run and, if low-geared, do you work it pretty hard? Also you could be getting evaporation if you use full synthetic. Some earlier models like dino oil better.

I notice it EVERY time I only run the V10 for short periods (like moving it in a parking spot a few feet or in/out of the garage) and THEN letting it sit for some time...upon restart as you have noted...POOF smoke...I can re-create it at will...now I am just careful to let the V10 run a little longer when started before turning off...
My V10 uses virtually no oil and I work her hard tugging my 9000# TT. I run Mobil 1 5W20 for 5000-6000 miles between changes and the Ex is basically my TV only now that we got the Mini...
How you been?...long time no talk...since we talked last...I installed the RoadMaster suspension on my Ex and that has REALLY tightened up the rearend...since I couldn't find a good panrod (sp?) solution available (LOL)
joe.

Hey Joe how are you doing? I use Fords blended Syntetic only since new. I don't drive the truck hard a all and it has 4.30 with 35 inch BFG tires. The truck looks and drives like new and has only 86000 miles. I sold my 35' camper but thinking about a driver. Yes I know I should let it warm up more and i will try to do better. Guys please keep posting about this topic. Thanks again. Ron
My dads old 99' 6.8l puffed some smoke at start up like described. His 03' used to do it from time to time, but he says it has yet to puff smoke since he put on the aftermarket high flo cat. The cat may have something to do with it. Never saw my 04' puff smoke but I ditched the stock cat at 17k for a high flow Dynatech unit.
My V10 will puff sometimes if you start it to move it a few feet then park it.
Its been doing that since it was brand new so I'm not the least bit concerned now.
That is normal, I have posted about it before. If you don't shut it down before it warms up you'll never see smoke. By the way my 05 has used about 2/3rds of a quart since new on 3000mi oil changes with 5-20 motorcraft from ford. 33000 miles on it.
Is it bad to just start your V-10 for a short trip or move and then shut it down?
Does it do damage to the engine over a long period of time?
IE...Unburned fuel, condensation????
Just curious..

Its not great for the engine to never bring it to operating temperature as the oil will eventually get contaminated with moisture.
But this may not apply if you don't live in the extreme cold.
Maybe I have it wrong but unburnt fuel is black. But oil that was sucked into the cylinders via stored in the PC system or coming thru the guides or rings would explain the blue smoke I get. Dumping fuel down an engine while cold or hot it will come out black not blue. Ford garage actuly pumped oil down the throttle body while it was running it started showing blue smoke. He also pumped fuel while running and it started smoking black smoke. He then after driving my truck around for a few hours at normal condition, he then turned it off and let it set for a whole night. He then started the truck and moved it about 20 feet and turned it off. He then removed all the plugs then he took a bore-scope and checked all cylinders for fluids. He found a fluid (mosture) in most of the cylinders, but very little on top of the intake vavles. Ford and the mechanic could not come up with a fix or could the factory service rep. A leak down and compression checks where performed and came up normal. Anyone have any thoughts about this? Thanks again. Ron

Sounds like a lot of work for nothing.
Moisture in a cold engine is normal.
A little oil pulled or draining past the stem seals is no cause for concern and can actually be good for the valve stems.
I wouldn't worry about this.
