Smoke when engine is cold!
white/blue smoke from exhaust when engine is cold. Notised it yesterday.
really a headturning smokecloud!
When reached the working temp there is no smoke at all.
Is this maybe related with my injectors not correctly adjusted?..
Thanks.
Under what condition? Starting? Backing off? Under load?
Sounds like it isn't burning up all the fuel. Is it running smoothly?
Could be the glow plugs. Particularly if it goes away once the engine has warmed up.
Fairly certain that the fuel isn't getting fully used up hence smoking but once it reaches operating temperature or you rev it hard then it gets full combustion so no smoke....
Just my two pence - but perhaps pistonhead or someone more knowledgable will pitch in here.
I was letting a mechanic have a quick look at the truck today, and his oppinions were, maybee something wrong with one or more of the fuel spraychambers/injection or maybe oil leak into the turbo.. (damaged turbo)
hmm.. I was i bit skeptic about the turbo thing.. but im not the expert here.
the glowplugs glows and the engine is always easy to start. everything feels and seems to be normal except for the smoke..

It is possible. If the smoke is tending towards blue it could be oil. What year is your G. There were problems on the earlier 350s due to overheating and hence warping cylinder heads.
Hi sounds like turbo seals. pull the pipe off the turbo leading to the the intercooler radiator... if it is WET with oil there is your answer. the oil collects in the intercooler radiator and on start up gets blown into the cylinders by the turbo..if you have not been allowing the engine to idle for 60/75 seconds after a journey to reduce the engine and oil temp before switching off the seals will suffer from the corbonised oil.best to get an exchange turbo orget it overhauled co's you cannot change the seals without taking the turbo apart and then it needs to be balanced.....there are other more sinister problems with the 350 engine which is basically an uprated OM 603. but lets hope this is your problem...
Clouds of white smoke leads me to think that water is getting into the cylinders. IE leak in your head gasket. With it happening mainly at start-up there may be just a small leak and as the engine heats the seals swell and closes up the leak once again.
Check the quality of your radiator fluid and oil. If the fluids do not appear as they should (if the radiator fluid is brown in color and/or the oil is either foamy or have water appearing in it) Then radiator fluid is mixing and getting into the cylinders.

I once had clouds of white smoak on a Peugeot engine when the head had cracked, they disapeared when it was warmed up, presume metal had expanded. Though you could hear engine breathing through expanssion bottle, Any bubbles when you remove pressure cap?
The water and expanssion bottle looks normal. I can smell its oil smoke. I think its a leak into the turbo.. My mechanic is back from vecation on friday and i hope he got time to take a look at it soon. Im still driving the truck every day, should i let it stand still till its looked over?
I need it in my jobb but if bad for it i have to get another truck till its fixed..
The smoke hasnt intensefide since last week. If im gentle on the throttle its not smoking wery much, still no smoke when engine is up in workingtemp.
Thanks alot for all interesting answers.

Hi just monitor the engine oil level more frequently...valve guide seals can cause the engine to smoke as well but more on the over run when the g weight has been pushing the engine.... like down a hill
Hello everyone! The headgasket was broke on one cylider, It was sucking the oil in that way. I was on my way to my mechanic to make a compressor test on the cylinders and check the turbo status when i heard a noise from the engine. I hope none of you guys will never experience that noise. It sounded like loose metal flying around inside the engine. I pulled over and called a towtruck thinking thats it for this engine.. have to look around for a new one..
But after changing the headgasket and flat grinding the head, its now running well with good compression. :)
nothing inside the engine was damaged :)
So im driving my G again after a few weeks in a rental car..
now with a empty wallet..
Hi Rollin thats good news ...you finally solved the problem...and nothing major broken ......
Hi Rollin thats good news ...you finally solved the problem...and nothing major broken ......
... other than his wallet, that is! :lol:
Yes it feels really good having the G finally running like it should! :)
Rather having a broken wallet than a broken G-wagen! :)
Have a nice day everyone!

Its when the engine is still cold. (after cold start).
When pushing the accelerator its not much smoke, it comes when i let go of the accelerator when rpm is going down again. Its smoking till the engine reaches its working temp. (10 min). The engine is running smoothlly and well, everything feels normal.
Im about to change the injection valves they are worn out, I know for sure the injektion is not 100 %.. maybe the engine is getting to much fuel injected..?
Thanks for replies
