I have recently brought a 1990 2.5 TD 90. this runs fine, and has had
new oil and fuel filters, air filter, oil change and a few other bits.
Fuels consumption is good, and no running issues on and off road. The
main issue I have is that when it is started from cold, for the first
minute or so, it blows out extreme amounts of very white smoke, once
warm, there is no sine of white smoke at all, when running or when
re-starting.

Any suggestions to the cause of this would be greatly appreciated.

Cheers in advance,

It's definitely the engine causing it.

Seriously, mine does the same thing exactly. It sailed through its
emissions test last month for the MOT, and doesn't smoke at all when
warm, even under heavy load.

My theory is that it's the turbine shaft oil seals. I'm guessing the
cold (and thus thinner) shaft allows oil to leak past, directly into the
exhaust side when cold, which causes the smoking. I think it makes a
better seal once the engine warms up and it expands. WIGART*, I intend
to take the turbo off and have a look. HBOL says brown staining in the
inlet indicates oil seal problems, but frustratingly that the unit isn't
user repairable.

Paddocks list the turbo at £343, so perhaps I ought to check it sooner
rather than later...

Cold diesel engines that are maybe a bit low on compression will do this
- it's incompletely burnt diesel. So long as it starts ok I'd just
ignore the problem.

It's *not* oil if the smoke is white, oil will give blue smoke. It's
unburnt diesel from a cold, slightly tired diesel. It might be worth
checking the injector pump timing - they wear inside and retard
themselves which probably won't help these symptoms either.

I think it *is* white, and I will check the injector pump timing. Many
thanks - relieved the turbo isn't about to go, at least not that I"ve
noticed!

I've seen some truck engines that make an impressively big fog on cold
mornings...

speaking of pump timing, guesstimated advancing of the 300 TDi's pump by
about 6 degrees has made it a much nicer thing to drive. Mother reputedly
kept a note of the fuel on a run the other day, so will see if it's altered
the economy at all.

I have had a few people comment that I should just leave it, "it
starts and runs so why change it" but it seems to be getting slowly
worse. I will check the pump timing, thanks, it was suggested that I
may have a cracked injector pipe, but these have all been replaced, as
one was cracked, so the fuel theory definitely seems correct.

Glad to see I am not the only one suffering from this problem :)

I have a swb 2.8 Patrol that does exactly the same. Thick fog, then OK
for the rest of the day

I'd have to agree. I wouldn't worry about it too much. I have a 2.5TD
in my 90 and it'd done it since i bought it 40K miles ago. U get a
puff of white in the morning and a bit on the over-run. But after its
warm its as clean as a whistle. The engines done 128,000 miles (as of
yesterday) and it still goes great. I'd just keep an eye on the levels
and keep changing the oil regularly

All the best

Turbo bearings will always feel worn, they are fully floating bearings. Oil
control at the turbine end is by a piston-ring type oil seal.

Could also be worn injectors, but unlikely if emissions test ok.

It's a common characteristic of these engines and I wouldn't worry about it.

Ok, I am not going to worry about this any more (there are enough
other jobs need doing :)), and as suggested I will keep an eye on the
levels etc.

thanks for all the comments,

Andy
