F250 Turbo Diesel engine won't start in cold weather . Smoke comes out the exhaust until engine warms up. Runs rough & loud until driven at least 5 miles
I've been having the same problem, does yours improve if you plug in the block heater? If I start it cold (under 40 degrees outside) without plugging it in, it will run very rough until it warms up. If I plug in the block heater, it will start down into the teens and run without issue. I thought it might be some sort of choke problem but have no experience with troubleshooting diesels.I've been having the same problem, does yours improve if you plug in the block heater?

It's strange that your engine is rough and loud for 5 minutes after it starts. I have a similar problem with my husband's diesel truck when I try to start it in the winter, except the engine is loud for longer than 5 minutes; sometimes it lasts for half an hour. I don't know what you're going to do, but I think I'm going to take the truck to a diesel repair service. http://www.hesperiaautorepair.com/servic...It's strange that your engine is rough and loud for 5 minutes after it starts.

It's normal for cars to do this in cold weather til the engine warms up a bit. If it's not cold you might have a head gasket going bad causing antifreeze to get into the engine.
What happening is you have a bad head gasket or its starting to go bad. As long a little oil is getting in to cylinders causing that smoke once it warms up that gasket is expanding thus the smoke stops. I would keep an eye on oil levels if it gets milky replace gasket asap. Could also be intake gasket but highly doubt it this sounds like a worn head gasket.
Nothing to fix friend. See, in diesel, when cold, there is an electric plunger on the throttle that speeds the idle a bit till warm up. Connected to that same wire is the cold start/temperature sensor. When cold/cool this sensor will excite the plunger to speed the idle, and put more fuel into the engine making the smoke you see, until warm up is reached and the sensor shuts down. You really don't have a repair needed friend.
This engine 'loves' glow plugs! One goes and the others try to handle the amps. Change them and you will have no probs! Other than that, I feel this is about the best diesel truck made!
Sounds like not all the glow plugs are working.It should run fairly smooth on a cold start if all of the glow plugs are working..Also you shouldn't drive off on a cold start with a diesel,Its really hard on the motors..At least give them 10 to 15 min on a cold start..The oil in them is a really thick oil and when there drove on a cold start theres no oil lubricating the internal parts and will cause the motor to seize up..You may already no this and dont mean you drive it as soon as you start it i just wanted to let you know..When you get alot of white smoke it could be two things,Theres water in the fuel which will make it not have much power die and smoke..But if it runs fine when its warm theres some bad glow plugs...Hope this helps you and have a great day
You dont say weather its a petrol or diesel engine as there a slight differance in the answer and if a turbo on a diesel thats even more of a differance, but taking it a petrol .
Well to start with the white smoke Isent smoke its water and after going through the engine it turns into Steam and thats what you see..
Running on 3 clyinders is caused through 1 cylinder isent working as a engine should and has a bad valve or a broken piston ring or more and even a cracked head and gasket letting the water through,,,also the broken ring works like a oil pump as if not firing given you power then it works like a oil pump and pumps it into the cylinder that dosent work only pumping oil into the hot exhaust system while running.CAUSING SMOKE
And if a turbo then could be the turbo bearings worn and pushing oil into the engine and still doing the same as before.
Let me know how you get on. RON
I have a similar problem - though my timing is right exactly where it should be
I'm wondering if it has something to do with the build up of carbon in the manifold... the smoke has a blue gray hue as well and defiantely smells like diesel
But I'm also zen with the fact that there's always going to be smoke upon a cold start up... it's the price you pay for a diesel... now if I can just get it back up to 50mpg instead of the 44 I've been getting I'll be happier
oil drop from the valve stem (from engine head to cyclinders)
or
diesel soot collect inside the exhaust system.
===
I will take a 5-10 minutes high rpm (not redline) ran on the highway.
Pay close attention to the rear view mirror and look for black diesel soot.
===
I will use Diesel Cleen or similar product to condition the fuel. (keep moisture down)
Use the recommended amount of SEAFOAM oil additive to condition the valve stem seal/rubber parts.
I can not rule out excessive blown by.
Can you get a diesel compression tester?
When was the last valve adjustment?
Please post the actual odometer on the engine and I will follow up on it.
it sounds like your turbo has packed in firstly the oil seal in your turbo has failed thats why ur seeing oil from exhaust & the whistling from turbo is the vanes in turbo breaking up so i would advise not to use car until new turbo is fitted & inter cooler pipes and inter cooler itself are checked & cleaned for swarf from turbo you can check turbo by disconnecting turbo pipe &inspecting turbo vanes (fins) to see if broken up or any damage to chamber.
