Cheers Ian, yes ive got it.

Well today was interesting, we changed the oil and filter the fuel (I think water was in it) and fuel filter and still the same, I took her for a run only about a mile or 2, when I returned to the garage the smoke had gone!!! :D

So it looks liks once up to temperature its ok I turned her off and left it 5 minutes started her up again and the smoke was back :(  so it seems when cold or warm it get smoke, when given a short run it's OK. :?

Does anyone think this could be the piston rings?

Mark.

Porny:
It could be piston rings, or valve stem oil seals (or even a cracked piston - not that common on 200Tdi's)...

If the smokes still grey then unlikely to be the rings, as typically if an engine is burning oil the smoke is blue.


It could still be that the timings out... or knackered injectors (partialburn)... or a few other things (like a bent con rod).

Has the timing been done properly - with everything locked in place - and not just 'by eye' like a few places I know!!!
Which injector pump did you use in the end?? The one off the Defender 200 Tdi, or the one off the Disco engine??  Which injectors?


You could do a compression test (and if low repeat with a squirt of oil) to see if it's the rings - I have got a diesel compression tester if neded.
At least it would rule one thing out quite quickly.

Hi Ian,

I forgot to mention the smoke looks more blue now than grey, the timing seems ok and starts on the flick, we put a pin through to the injector pump so it lined up, turned it twice and it still lined up, I used the injectors off the disco as the injectors were left in the block.

so a compression test will tell me if the rings or piston has gone?
