i recently purchased a merc 609d minibus 1987 d reg.
the vehicle was purchased from a coach operator and was maintained well through its life. however as the vehicle got too old for school contracts was parked up and left stood for almost 2 years!! On starting her up there was White smoke for around an hour whilst on tick over in yard, once we got it out of the yard and gave it a run the smoke turned from White to a very Pale Blue colour! On acceleration more blue smoke was produced on tick over/idle it was minimal.
We got the Minibus back to garage changed oil filter fuel filter and small filter inside glass, (they were filthy black) also changed oil with some fresh rock oil, however hardly any difference at all, we was also told about lucas oil stabliser which is supposed to free off pistons valves etc, we put this into the oil and the smoke cleared instantly we ran it up the street and back and hardly any smoke even on acceleration!
Until next morning came to start it good old bluey white smoke again, we took it for an emmissions test and it failed, its non turbo so you are allowed 2,50m however we averaged at 3.05m. Whilst emmission test was being carried out when revving the engine the smoke made our eyes sting and water, however did not smell directly of oil nor fuel! then we was told to try injectors so we have taken them out and each nozzle is badly gunged up in fact you can hardly see the holes they look like half flattened sand castles!
We are taking them to be tested and overhalled! Could this be the cure or could it be more involved Please let me know asap! Drivin me Mad! Thanks

. put them in and still loads of Blue Smoke, It doesnt smell oily but very very diesely when revving it, it burns your eyes real bad! Hearing lots of different opinions people all agree tho that it could be over fueling could this be so??? your opinions please! Thanks xx
