Smoking like a train

Morning,
After nearly completing my landy, I took her round the block
last night and can't believe the smoke. Its constantly there at
tickover a lite but visable smoke, but when pulling away smoking
like a train! I would say its fuel but not 100%. I have a 200 di
in, (with a defender turbo the high one waiting to go on.) No
air filter on yet.
Could it be over fuelling because of the lack of a turbo have
those on here that run di adjusted the pump? No bubbles in the
rad, Starts first time instantly no heat, Sounds ok, when
cracking injectors they effect the engine note.
Any experience welcome.

it is light, and smells of fuel, you would say white blue, not
black or dark at all. But its not using any water so far. I will
take it for a hammering tonight and report back tomorrow.

White smoke = water in exhaust or late fuel pump timing causing
unburnt fuel.
Water billows (like a steam locomotive) as opposed to late
timing which hazes.
Water could be caused by cracked head, blown head gasket or a
cracked block.
Late timing can be caused by air leaks in the fuel system. If
the air gets into the pump, the plungers have to compress the
air before they can supply enough pressure to the fuel to open
the injector which takes time and results in the fuel being
injected late.
Restrictions or air leaks in the fuel supply to the pump could
cause similar symptoms.
In any case, I would have thought to get it to run properly
without an air filter or turbo fitted you would need to adjust
the timing on the pump. I might be mistaken on that though, as
I'm more familiar with carbureted petrol engines that these
smelly diseasel things.
Cheers
James

I wouldn't see it as good practice to start adjusting things
until the system , any system, is complete. My preference would
be to build up the engine as you want it to be then conduct
diagnosis if the problem persists.
Sorry that's not actually that helpful, but it may prevent
headaches later :)

Echo what the guys above have said really
Have you run this engine before installing it? Has the timing
belt been changed?
Sounds to me like unburnt fuel, a good drive may help if it has
stood for a while or you need to check the timing, injectors
etc.
To the best of my knowledge you don't need to alter the pump for
running non turbo, the boost diaphragm for injecting more fuel
relative to the increased air under pressure from the turbo is
disconnected so should run along quite happily.

Very unlikely in this case but an overlooked cause of white
smoke can be a failing brake servo. My '66 109 had a remote
Girling Powerstop servo on it when I bought it, worked fine for
a few years then I noticed white smoke on overrun. I couldn't
work it out...until the brake pedal went to the floor. I was
very lucky it happened on the drive, evidently a seal had failed
and it was burning brake fluid. :eek:

Still smoking, just the same, The engine was in a project S111
100 inch coily which we bought. Which was never finished so it
has been around for a couple of years but i would say its was
good enough for them to start to use it. Time will tell.
I am going to run it out of a small container of diesel near the
pump to eliminate any possible air. I think its over fueling, so
could be timing but it starts and runs so well I dont want to go
into that and disturb anything.
The boost part of the pump just has a pipe on it at the moment,
I imagine this could effect it on way or the other.
It was all going so well, the install and connecting everything
up until it came to driving it! Been forum surfing for others
experiences so will re read over everything.

If it were overfuelling the smoke would be black.
Is the smoke actually smoke, or is it water vapour?
Is the exhaust new? In my expereince, newly rebuilt engines are
often smokey as they burn off paint/comtaminants from the
exhaust and the various gaskets.
Put and air filter on it. Bleed the air out. Then test again.

Been for a bit of a run. It was a new exhaust! and the engine
had been stood. It seems to get better and better the more I run
it. It didn't go trouble free however. It shat itself of oil
from the oil rad pipes stopped to check it after pulling up a
hill. Had a split in one pipe it never a drop come out for the
hour or so I've bin running it in the garage the bastard. Time
to go home I thought. But the smoke deffo is reduced but perhaps
that's directly proportional to the amount of oil that had
pissed out everywhere in the engine bay. It was a right mess
like a blood bath. More oil, any oil thrown in whilst still hot
and run around. Shall see Tomoz when I replace the oil about the
smoke.
On the diagnosis. Checked for leaks in the fuel pipe, also not
pressuring up. Not effected by the servo pipe. But no fuel
passing by the blow back pipes on the injectors at all. When I
take the pipe off the front one I was expecting it to bubble and
spit out. Anybody pulled one off before? Perhaps the injector
isn't blowing off and spitting all it's fuel into one pot?
Anyway more jobs before I'm fitting the turbo. And the mot.
Check the engine after changing the oil. Fuel gauge. Temp
sensor. Oil gauge. And pressure.
