My parents have a Hiace Supercustom with a 2L-TE Turbo Diesel.
Me and my brother are getting it ready to go back on the road, it's been sitting since last summer. It was quite smoky when it was last running, especially on cold startup. We thought it might be the glowplugs, but after cleaning them up and testing them they seem sweet, and the engine is still smoky. It does clear up a bit once it's warmed up, but there's quite a bit when you race the engine. I understand that diesels ARE inherently a bit smoky, but would like to reduce it as much as poss.
Workshop manual suggests injector nozzles or injector timing could be the problem. Neither of us have much turbo or diesel experience. Any ideas / suggestions appreciated.
Also sorted out some of the wiring around the glowplugs as it's had the engine replaced at some stage and whoever did it did a very messy job. (eg twisted wires with elec tape)
There is a thick cable going to the glow plug power rail, and then there is also a light gauge cable going to the same rail. What does this little cable do? Seemed to start and run ok without it but I'd like to know what it does. Anyone know? Will try to get photos tomorrow.
thanks!
