Well what the mot guys said to me was that i need to get a new air filter as i havent changed it since i bought camper in feb and it probably hasnt been changed for a long time.
For an older diesel to fail the mot smoke test it has to be real bad....I suspect the test was not carried out correctly, was it left ticking over for ages? A good thrashing will normally shift most of the soot and allow a warmed up engine to pass its test, if not, take the LDA pipe off and try again....if non of those work its maybe had it.
my old jx passed when the turbo was really bad. no exaggeration, you could not see out the rear window on the way to the mot station. The trick with mine was to let it get up to temp and ignore the smoke cloud, then engine off then on again and it wouldnt smoke for about 20 mins
You don't need to try a filter to know if that's the problem...take it out and look at it, if it looks fairly ok...it's ok! Try revving it up with no filter fitted and that will rile out the filter... Is there heavy white smoke...a bit of general smoke...how is it on the road? How's the timing? Is the oil level correct andits the dipstickreadingproperly (I bet it isn't...only way to know is dump out the oil and start again)
My old girl smokes like mad if the oil level is even a couple of mm over the level on the re marked dipstick...

When i first start the van up there is white smoke for approx 3 seconds then no smoke driving it.

Changed oil 2months ago.
Oil level is fine.
When you say oil level is fine...how do you know the dipstick s correct? Did you measure the oil before it went in?
Dont know how to check the timing.
