Hi - newbie here with a tale of woe.
I dropped an International HS 2.8L engine (upgraded 300tdi lump) into my 200tdi SW - ran like a dream until the first emission test last week during which the engine was revved up to 3500 rpm - after a minute or two the thing literally went up in smoke. The following resulted:
1. Plumes of white smoke at idle and when running - smoke smells of diesel, not steam
2. engine runs rough - clearly one or more cylinder(s) are misfiring
3. oil trickles through turbo into exhaust.
Interestingly, when the turbo is disconnected, the smoking stops, at least at idle
On the input side, the Bosch service centre confirmed that the injectors are b*ggered - looking further up the line at the fuel filter and the fuel tank, looks like contaminated diesel - cloudy with tiny particles. My hypothesis is that the hard revving sucked in debris ina few minutes which may other wise have taken a leisurely few months to build up.
On the output side, I have been advised by the Intl agents that likely cause is restricted air filter or too much engine oil - pretty sure neither was the case. I am also advised that this could have affected one or more of the pistons / piston rings.
I am not sure whether I am dealing here with more than one issue. Any views and advice would be much appreciated!!
Thanks.....
