Hi everyone,#
Yesterday was out enjoying the nice weather with the family heading to Wrexham when on the motorway I seen a cloud of black smoke behind me at this at this point I wasn 't sure it was mine, couple miles after noticed a whistle noise on deceleration I stopped to check if it was the noise from the turbo looked for any split pipes, intercooler looked fine, all vacuum pipes connected, no noticeable loss of power.# Decided to carry on with my mate behind on the td5 he also confirmed the black smoke earlier on was from mine! Few more miles on the motorway my mate confirmed no smoke whatsoever. Finished the day and returned with no problems seem to have a tunned turbo, lol.#
Today removed all pipes and there a considerable amount of oil in the admission and at the bottom of the intercooler the shaft of the turbo had very little play.#
Thinking about it I have a lot of white smoke first thing in the morning for the first 5min I was trying to work out was was it, I now might have my answer it seems to be the turbo. This is on a 300tdi with 127k.#
Does anyone think might be something else before I start to look at turbos will have to buy used no budget for recon or new, couple weeks ago was the read diff replaced not very lucky but I suppose it's a land rover.# I'm not the most mechanical orientated only starting doing things thanks to YouTube, :) so go easy.#
Thank you#
 
Sorry just to add the "whistle" noise is also on acceleration from low revs 1000rpm and upto 2300rpm. Still a lot white smoke on the morning.
 
you got it warmed up nicely( operating temps) and it cleaned the crud out from driving short runs. A diesel needs a good work out to function right. Turbo whistle is very common. Nothing to worry about IMHO White smoke on first start of the day not a issue
 
Has it used water or oil?
Turbo whistle will be a split or holed pipe somewhere, could even be the intercooler corroded and holed., or maybe exhaust.
Black smoke could be soot burning off in exhaust

White smoke not sure...condensation ?
 
black smoke is excess fuel or not enough air, check hoses arent collapsing internally etc run engine with hose from turbo to intercooler off you should see if oil is dripping out

Never had issue with that Landowner, and can hear turbo wind up when window is down.;)

And condensation on the second part:tea:
 
Thank you guys for your replies,
the whistle is very noticeable and I can say loud, reading online some people seem to suggest when a loud whistle start that will a perished oil seal internally and excessive oil loss and oil building inside the intake, my mate has a 300tdi and no noticeable loud whistle like mine, intercooler seems fine no holes.

If you reduce back pressure or derestrict the inlet then turbo will whistle so could be that the soot all burned out and cleared exhaust or small hole in exhaust, Air escaping between turbo and inlet manifold may whistle if the hole is right for whistling:)
 
Forgot to say no water loss, after the weekend run I noticed slight drop on oil level more than usual as the weekend before done a good run with no noticeable oil loss.
Exhaust is perfect recently fitted decat pipe had a proper look underneath.
 
Gees, I live my turbo whistle :D I have holes in the air intake to the turbo, will be changed with the new snorkels installation.
 
As for the white smoke on the morning, is it hard to start ?
If it is then it maybe the injection timing needs reseting.

I know on mine when I do lots of stop and go or short runs, when I get on the motor way and plant the right foot to the floor and run it to 80 there is some black smoke when them 300 pony's and the VNT kick it all in SWEET:D.

And on first start of the day there is white smoke for just a few seconds, summer weather never seen any.

204k miles on the beast ;)
 
Just read in here and there a danger of this becoming a runaway i.e sucking engine oil up through to the turbo, lots of black smoke and unstoppable! Better thing to try and do is stall the engine in gear just by using the brakes. All my symptoms seems to match this before it happens, lol.

A belch of black smoke when you put your foot down is not a run away:rolleyes::rolleyes: Diesel is a diesel as well as a turbo is a turbo:tea:

I agree with the first part but a vid of a 1000hp specialist engine burning nitrous is not very informative in context.

Just sayin :p
