Surf looks like it's running on coal !

My Bushwacker Boyo Sir,

You are indeed correct, I moved from a coal loving 20mpg to a bunny loving 25mpg.

Typos always occur when you rush!

I sit corrected.

Delayed black smoke release

I have a 1991 2.4 automatic Turbo Diesel Hilux, I probably do 6 miles a day round trip to work (yes I know I probably should cycle to work), Anyway

It has been blowing noticeably more black smoke on hard accelerations, and even more if for example I am approaching a roundabout and do not need to stop but accelerate away. No visible smoke on idle or if steady cruising (as far as I can tell). It has been like this for at least 3 years, about a year ago I had a full service done (thanks TonyN) filters and fluids replaced, it did make a difference but my paranoia and friends comments still keep me worried. I took it to a garage and they did not think it was the injectors as the black smoke release on a hard rev was not immediate but was delayed after putting foot down (ave 1 sec delay). I got recommended a new additive to use (redex did nothing for me (or my truck)) this new stuff did seem to work as for the first time in 3 years my surf made it through the MOT emissions test first time

readings 3.10, 2.88, 2.66

So if it is not the filters, or injectors, does anyone have any suggestions for possible areas to investigate?

Is it down to the minimal mileage I am doing?

in which case im thinking my timing is out which I suspected for some time. when it gets into OD at low revs it judders when cold

Hi Everyone

After I posted this thread I went to the garage and bought the red ex, I have gone to South West Scotland and ran the thing with less that 1/4 tank of fuel in it with the redex stopped at 4 garages and put in 10 quid then bottle of redex it's helped but didn't cure things Iv'e also checked my fuel consumption at 55mph and getting about 19/22mpg !! smokes really thick if it's been running in traffic and I put the accelerator down afterwards.

Can anyone describe where to find this value thingy to clean it. I haven't used a drop of oil it's got to be fuel when I first got the truck and got head done Stevo said it was the cleanest burning Surf he'd seen so somethings gone wrong. I don't want to take it to my local garage co's I need to book holidays and find overnight accomodation if I do.

Cheers John

This Andy Bud is just a bit lazy, the Bud is a downsized version of a longer Polish lastname

It's a device to let exhaust gasses re-enter the combustion chamber so that they get burnt a second time to stop the polar ice caps melting.

Thanks I will give it a go the truck seems to be juddering slightly under accereration pulling away is ok but as I drive along with the engine just pulling it's juddering a bit could the cam belt have jumped a tooth! Or would this be because of all that too rich mixture unburnt fuel.

Cheers JB

[Highlander1]

I think juddering is getting more like a slight misfire!

[Highlander1]

Yes there's definatley a wee miss when accelerating not huge but noticable

[dirtydog]

what could cause that?

[BUSHWHACKER]

Go to be pump timming.
