Smoke & Injectors
bigfatsi:
--- Quote from: "davidlandy" ---depends on where the exhaust is blowign but could be...
exhaust is blowing and the turbo not spooling up enough = not as much air, therefore more unburned fuel = black smoke
I think

Another good possibility. As is flogging it and buying an Audi! :lol:
Only kidding before the flames start!
Will check all bolts studs as soon as there is some daylight to work on.

Have you checked the rubber diaphragm in the injector pump yet??
It could be that this is stuck in, split, or badly adjusted....
Or that some one has been playing around with the pump - you could try turning the fuel down.
You could also have a stuck injector....
I've got a set of as new Injectors for a Td - only fitted for a hundred miles... then I found the real cause of my problems.
Would happily sell these for less than £88 - at the moment they aren't doing much!!

I checked to see if the pipe from the injection pump to the turbo was full of diesel which it wasn't. All the screws and nuts on the injector pump have been paint-marked or wire secured and look untouched.
How much for the injectors? How many threads can you see in the middle of them where the 'bottom bit' screws on. Seems quite a few on the one I took out. 6mm gap (ish)

If you are getting Black smoke, you are not getting enough air. You are overfuelling.
Before you start to spend money, check the air filter, the Turbo Hoses and make sure the Turbo hasn't got damaged blades.

Update:
Checked injectors and found that the steel washer on the bottom was missing from all of them. Replaced and found that the engine started running really rough. To the point where I was taking steep speed bumps in 2nd! :lol:
I got under the bonnet and removed the turbo intake pipe to make sure it was still spinning and could feel a regular 'blowback' through the turbo. Whipped off the rocker cover and checked the clearances. One was miles out to the point that it didn't even touch the valve. Tightened it up and I now have a new engine! Power is much better (All the guys that say the TD is underpowered should try it on 7 valves lol) and the smoke has cleared. Not entirely but to the point where it doesn't embarass me to drive it 8)
Also a new rocker cover gasket has stemmed the oil from the 'injector'. :oops:
So thanks guys for all the help. Now I can move on to the electrics!
Simon.
