It may just be me ... my motor seems to be very sluggish until the Turbo hits around 1500rpm then woosh and before you know what has hit you its time for another gear. Is this standard for the 3.0DT motors?

Cheers for the reply... this morning was the coldest so far since i bought it - sunny lancashire was not so sunny and it run like a slug.
When it warms up its great - pulls like a train even with 3ton of Ifor box on the back.

Hmm, don't think it was actually made by Cat although they did the design work on the brilliant/*beep* injection system depending on your viewpoint/experiences! I may be wrong though and stand ready to be corrected.
When it's running right, it's a brilliant motor. Very powerful. I should imagine you could have that "lag" chipped out couldn't you?

Hi
Dont want to worry you but I recently had a problem with my 3.0 duty, it turned out to be the oil pressure sensor. The first problem I noticed was it ran like tractor until warm as if the turbo was not kicking in, since having the sensor changed it's like *beep* off a shovel even when cold. Maybe it just feels like that because it ran so bad for so long.

How much was the sensor? Is it something easy to do or a garage job? And are there any recommendations for garages in Lancashire area?

It may just be me... but i seem to notice a lot of black smoke even from "normal" driving - IM say no outstanding campaigns and i have not seen any increase in oil levels etc.
The car did have an engine rebuild in february before i bought it... work totalling £3500 including new turbo.
It does drive fine - a little jerky in traffic and zero power until warm.
Ideas?

So thanks to CAT (who should know better) they kinda gave Isuzu a bad name, well there engine at least,
I wonder who pays for the recall work to be done then? cat or Isuzu, both?

Chris,
Maybe you have got to the root of your engine problem now, but if not it may be worth looking at the EGR valve. Sure that has been mentioned before on the forum. Have just had the one on my engine unplugged by the dealer to see if that is the cause of its sluggish performance.
Now there is (more) black smoke and the engine seems to take a little longer to warm up. Both of these may just be my perception though! Not convinced it has cured my problem though. Any other suggestions?
Cheers |

| Having just written the reply above now noticed the more recient thread. So guess you have probably already had the EGR brought to your attention! |

Still the same if not worse... im going back to the garage i bought it from this weekend. I have started to notice a serious delay between pressing the accelerator and the engine responding... i know its a diesel but its as if i have to wait for pressure to build somewhere before the engine gets fuel.
Spoke to another local dealer the other day who reckons i should expect a letter for the injectors but nothing else! This contradicts IM and the next nearest dealer who told me to expect a letter for the ceramic cabin heater.
Im confused 
The bad starting has been really noticable recently with the cold weather - the damn thing starts on two/three cylinders and is very lumpy and rough until warm

We think possibly both although there's absolutely no proof of this, just that Isuzu has suddenly started being reasonable about warranty claims on the 3.0 when before, they were stonewalling to a large degree, so it's quite possibly that cat have coughed if you get my meaning...

Hi Guys - just a quick update... it has been back to the garage and has been plugging into their computer (tech2?) all is apparantly fine. I have noticed its a little better filling up from Morrisons instead of Texaco?? Strange but true. However it still kicks out quite a bit of black smoke under normal driving - any ideas?

About your black smoke not really - most turbo diesels kick out a puff of black smoke on initial acceleration and then again if you nail it after a period of steady state running, but how much is too much? I would say if it failed the MOT test and the fuel consumption was way over the norm. Apart from that I wouldn't worry.
As for your fuel supplier - the yanks are convinced that different "brews" from various manufacturers affect the motors and consumption/performance variously, whilst others on here are adamant it comes from the same suppliers anyway so is basically all the same. I don't subscribe to that and have better results out of Tesco than almost anything else.

It sailed through an MOT only 6 weeks ago ... and i would say it was the same back then.
I do plenty of motorway miles and am currently getting 500 miles (ish) from a full tank so fuel consumption is pretty good.
