shavenYak Posted November 20, 2010 Share Posted November 20, 2010 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! Quote Link to comment Share on other sites More sharing options...
shizzl Posted November 20, 2010 Share Posted November 20, 2010 what colour smoke? i had a surf that smoked quite bad(white ish blue)mainly on acceleration from idle and cold start up, put in a catch can and it sorted it, cos it had blow by.. my tranny van was smoking thick black smoke cos of over fuelling, adjusted the fuel and shes sweet..

Not blue, and it's not going through any oil. It's mainly sooty black, but when you rev it changes to white, then black. The manual says if injection timing is the problem then black indicates advanced timing, white = retarded, but it doesn't mention getting both black and white!

RUNAMUCK Posted November 20, 2010 Share Posted November 20, 2010 how many kms does it have on the clock? I know SFA bout diesels, but it's my understanding that they smoke like fuck when the injectors are coozed. Knocking back the fuel pressure might be a starting point though.

shizzl Posted November 20, 2010 Share Posted November 20, 2010 see if you can pick up a set of injectors for it... i take it its a 1kz.. these go fucking good when theyr going....should be a heap around that are getting wrecked try winding back the fuel a bit until it stops smoking,get its wof, then wind it back up until you get it sorted Quote Link to comment Share on other sites More sharing options...
UTERUS Posted November 20, 2010 Share Posted November 20, 2010 1KZ injector pumps are electronic, no manual fuel adjustment on those bad boys. Don't waste your time with second hand injectors, get them cleaned by someone with the right gear. Quote Link to comment Share on other sites More sharing options...
shavenYak Posted November 20, 2010 Author Share Posted November 20, 2010 It's not a 1KZ.. it's a 3L (not 3 litre) Quote Link to comment Share on other sites More sharing options...
fuel Posted November 20, 2010 Share Posted November 20, 2010 hrmm I thought 3L and 5L's didn't come out turbs? Has it had 2L-TE gear put on it? Quote Link to comment Share on other sites More sharing options...
shizzl Posted November 20, 2010 Share Posted November 20, 2010 that clears that up then...not 3 litre, but a 3l... should have mech pump then, so try and wind it back untill you get injectors done.. the very first thing id try is clean the air filter,if its blocked itll also cause that Quote Link to comment Share on other sites More sharing options...
shavenYak Posted November 21, 2010 Author Share Posted November 21, 2010 hrmm I thought 3L and 5L's didn't come out turbs? Has it had 2L-TE gear put on it? Sorry my bad, yeah must be a 2L-TE then.. Quote Link to comment Share on other sites More sharing options...
UTERUS Posted November 21, 2010 Share Posted November 21, 2010 Is it 2L-T or TE? TE means it has an electronic pump and you can't adjust it. But really, i wouldn't go fiddling with the pump just yet. Get those injectors cleaned. If the glowplugs have not been replaced, they are likely pretty well past their best, although will still mildly work. Make sure all the connections on the power rail for the glowplugs are tight, sorry i'm not sure i remember seeing a small wire on mine. How long do the glowplugs stay on for?

The glowplugs get power for about 10 seconds, then the car beeps and they turn off. I'll take some photos of the wire tomorrow as well.

Ranter Posted November 21, 2010 Share Posted November 21, 2010 From memory I think the thick wires go to the top of the manifold with an insulator separating them, only the thin wire goes to the glow rail. There is a similar setup underneath the manifold that is real hard to get at, that I think is an afterglow setup. Either way the glows should stay on after the car is started, be sure to get the glow system correct before turning to injectors, then to tight tappets etc. Quote Link to comment Share on other sites More sharing options...
Jase Posted November 23, 2010 Share Posted November 23, 2010 2l-te's are a tricky one the pumps are not to be touched!!! i've had a 2l-te surf and it did smoke alot i found it was the wastegate all coked up and not closing completely i added two 2.5mm washers behind the actuator bracket to apply some more pressure and it subsequently burnt off what i couldn't get with a scraper. also went way better afterwards.

Jase Posted November 23, 2010 Share Posted November 23, 2010 mine pulled way harder (auto on 34's) and ran cleaner i was told by a diesel tech that they overfuelled a bit from factory and that adding a few psi was quite safe, i then researched via the net and the 2.5mm washer trick was pretty common in ozzy.

CaMpylobacter Posted November 23, 2010 Share Posted November 23, 2010 yuh more boost isn't going to hurt them, compared to more fuel, y'know. but yuh his is leaky oil seal spec turbo so getting home job rebuild.lol Quote Link to comment Share on other sites More sharing options...
