just been out offroading and as soon as i went on the road it started getting slower loads of black smoke,and over heating ,i had the head gasket done 1k ago ,now for the interesting bit when i rev it the hose to the intake manifold sucks flat like its staving of air ..its a disco 200 tdi
-
air filter clogged?
-
tried that thanks
-
It sounds as though either your intake is blocked, or if youve been offroad, it the intercooler blocked??
Check your air filter first.
-
do you mean the fins
-
is the pipe thats sucking flat before or after the turbo (sorry not that familiar with the TDi engine but good with engines in general)
H
-
as the turbo kicks in
-
am thinking that if its after the turbo that your turbo bearings ahve collapsed and the turbo may have seized, the bearings going would allow engine oil into the exhaust hense the black smoke, its sucking flat because only limited air will make it past the turbo and the dramatic loss of power should be obvious.

yes there is no power at all on turbo,the 2"pipe from the intercooler to the manifold goes flat like it cant suck
-
If you have a blockage on the air side, then the diesel being burnt will cause the black smoke. I.E if it is a very rich mixture.
Try taking the pipe off before the turbo and see if it still does it. If not, then looks like an intercooler fault.
KEEP YOUR HANDS AND OTHER THINGS OUT OF THWE WAY.
-
can you tell me what can go wrong with thr intercooler please
-
or the inside of the air hose has delaminated and is sucking flat blocking the airway?
-
get a hose pipe, Not a pressure washer, and try and wash the fins out on the radiator and intercooler. If they are muddy, then it will need a good clean.
This could be causing the overheating.
Did you got through muddy water, or anything that may have gone throught the grille?
Is it a 200tdi??
-
its going flat because something prior to that is clogged and if your filters clear then it can only be your intercooler or turbo. I'd take the pipe off and see if there is any oil in it. If there is then I would lean towards the turbo bearings having gone.

the black smoke is def un burnt deisel
-

This does exactly what it says on the tin.
It cools the air going into the engine, and thus makes the air more dense (you can squeeze more in) This is what gives you more power. Coupled with the turbo blowing it in to the engine, loadsa power. If the intercooler cannot supply what the turbo is asking for, then it will create a large vacum. This will cause the hoses to collapse as they are the weakes part.
-
just looked the fins arnt to bad,is it possible to test the torbo
-
Cover the air filter inlet with your hand. Does it suck really hard and try to stall the engine. Or is it not making much difference.
As i said before, did you go through muddy water??
-
sure ive been thrugh loads of deep water earley in the day it was muddy and coming over the windscreen the air filter has got mud marks but its not all covered
-
take the hose that is collapsing off. and run the engine. Is it still sluggish?
Also, try washing the rad and intercooler from the back to the front, as the mud will be right in there.
-
would a dirty intercooler stop the air flow
-
only if it was dirty on the inside :roll:
take the short elbow shaped hose of the turbo and start the engine, it should blow out of there
if not your turbos sha**ed

Did you take the pipes off??
How did you get on?
-
tanks guys cant do no more till tomoorow
-
See I told you they'd be a helpful bunch of chaps, didnt i bombx3!
Glad we both got home though!! and it was definatel unburnt diesel, I was behind him all the way home!!
Fantastic day out though!! :wink:
If you are fixed by next weekend then some of the others from here may go to the Trago Mills track for a play. I'll let you know!
-
I reckon on a hose collapsing internally
Ask BigA he had the same on a 90 TD Black smoke and no power
Darren
-
i hope its a hose ,jiffy man have you ever been trago?
-
Nope, not yet! :wink:
It's supposed to be £5 for a lap. which is about 2.5 miles long, but there are several sections there apparently.
Although it's supposed to be a 'lap' Phoenix Chris went there and spent ages there.
theres a 'winch' only section too. Have heard that it is always being improved too, gotta be worth £5 just to see! PLUS its on our doorstep too!
(off to do the pix now! :D )
-
been there twice now will never go there again my mate went round in his fiesta you cant go of the track took me 15mins £5 per lap borin
-
chris must of fell asleep,dont no why they call it a winching section cause you cant get stuck not jokin you will do one lap and never bother again
-
Oh, ok, well ,never mind, I'll just do the lanes for free then!! :lol:
-
i no a few ,and i have our own all weather steep section in the old gravel pits you can play up there for hours
-
If your air filter is clogged be it either dirt OR water then it will cause the pipe to suck flat as the turbo creates a vacuum between itself and the filter. The black smoke is the unburnt diesel.
Probably you had a dirty filter to start with then you have soaked it.
Take the filter off and then try it.
-
I'm told the bottom pipe to the intercooler collapses internally quite often, not a TDi expert though (not yet :roll: ).
-
all done the intercooler was partly blocked had to wash it out now it goes better than it ever has Thanx all who helped

Glad you got it sorted mate!!
