why me !!!!

[Hawaii]

afternoon all

looking for a bit of advise, just been to dorset for a week with the caravan and she towed lovely which I hope means that getting the head done and fitting the additional ATF cooler has sorted that.

now the bad news

coming home I was climbing a steady gradient, with the caravan on the back of course, and she seemed to lose a lot of power and checking my mirrors, she was throwing out loads of thick black smoke.
Once at the top of the hill she seemed fine (no overheating) but just down on power when I would normally expect the turbo to come on and again loads of black smoke out the exhaust.

As she normally doesn't smoke at all I got worried so stopped and called for recovery home.

She's in the loacl import specialist today to see what's going on but I just wanted t oget any input from members who might be able to shed some light on what's wrong.

As it's black smoke then I'm assuming it's overfuelling which would normally indicate that it's either the injector pump or the turbo. She starts as normal and runs OK until you step on the acelerator and then black smoke again

anyone got any idea's????? if it is the turbo anyone know where I can get one

Hope it's not gunna be expensive mate.

I can't really comment as I haven't a clue but good luck with it.

cheers for teh good wishes but ideally wanted a more techie response

we'll see what the garage says tomorrow.

Hopefully, rather than the turbo itself, it might be a sensor as it appears that she is getting too much fuel and not enough air, hence the black smoke, which seems to indicate that the turbo isn't doing it's job right.

Apparently blue smoke (oil) would indicate turbo failure, white smoke/steam (water) means possible head gasket probs and black smoke equals unburnt diesel

might also be the wastage actuator, boost sensor or one of the connecting pipes - I haven't heard of the surf 3 litre turbo's being a weak point

fingers crossed

- I haven't heard of the surf 3 litre turbo's being a weak point

Its not, a quick look at the fault codes will tell of any fueling issues that are sensor controlled.

If all the filters are free and its getting fuel to the pump, sounds like a correction resister or maybe spill control valve problem, they should get flagged on the check light, as well as over or under boosting turbo.

Also could be something on the vacuum side, how long ago was the head done? Has a vacuum hose or plug come adrift, it'll make lots of smoke if its getting the right amount of fuel, but somethng esle is shutting off airflow.

good news

just heard from the garage and problem is nowhere near as serious as I thought.

Theyv'e plugged her in and there are no fault codes stored, tested the wastgate and boost pressure on the turbo and theya re both fine.

seems like it's just a matter of dirty injectors and they are going to ultrasonically clean them tomorrow and bung in some cleaner as well.

then it's a rolling road test and emissions test before I pick her up later in the week

That's good news! Do you use any sort of fuel treatment in your truck? I'm not sure what you have for diesel over there, but it's all low-sulphur over here, and you need to add something to lubricate the injector pump, and it helps keep the injector nozzles clean as well I'm told.

nightmare

mornin' all

well good news doesn't take long to come back and bite you on the arse.

Picked up the truck last night with a new MOT (no advisories again) and a small bill for diagnostics (no fault codes) and injector cleaner - happy boy.

Drove to work this morning (motorway) and although initially everything seemed fine as soon as I hit the first gradientl where I normnally expect the truck to power up she dropped out of overdrive lost power and loads of dark grey smoke out the exhaust.

She bottomed out at about 60 ish, out of overdrive and wouldn't pick up speed again until got to the top of teh gradient - sad boy

Now obviously I need to get it fixed as we are due t ogo to the Isle Of Wight in 2 weeks with the caravan - anyone know what might be wrong (Tony, thanks for the heads-up re resistor/spill valve, the head was done last October so don't think it's the vacuum side)

and more importantly how to get it fixed - I need to find a specialist somewhere locally (previous garage although badged as a jap expert won't be seeing her again) and get it diagnosed & sorted in the next 2 weeks

fingers crossed

Have you tried chequered flag in Leeds, I know it's a bit out of your way but what they don't know about surfs isn't worth knowing.

Not had any experience with them myself but my friend took his surf in for the head doing 18 months ago & no problems to date.

I'll try & find the number for them.

Timing belt skipped a tooth?
Has the turbo been checked for wear?

[Hawaii]

maybe some good news

key cars in Thorne (import specialists) are having a look over it this afternoon.
Apparently the previous garage might not have had the right diagnostic gear to fully check an import but they do.

here's hoping it's not too serious - don't think it's the belt as that was changed last October (with the head) and, apart from when she's under load, she runs fine

fingers crossed

Hey Alan I know ya running a 3rd gen but had similar last may on the way from Scotland, 2nd gen (uphill struggle) I was using 100% WVO tho, do you/ have you run Veg ?
I changed all the usual filters before going (bar the breather on the tank)
I found releasing the fuel cap made no difference so to diluting with 1/4 tank of Derv no probs 300+ miles home.
On inspection of the breather on the tank it seemed "us" so replaced it, no more probs ..
Good Luck

all

engine wise she's standard apart from blocking of the EGR about 4 years ago and I've only ever run her on diesel.

The more I think things through and the suddenness (is that a real word?) the more I'm thinking it's something connected with the turbo. Just hope the garage can sort as I'd hate to have to get rid of it as it's the best truck I've ever had

more head scratching!!!!!

right, just got back from import specialist who plugged the truck in and not a single fault code recorded.

they summise it's therefore something mechanical and asked when the ATF was last changed??? as this may be causing the box to change down early, revving teh nads o and causing it to smoke

But if the changing down is because there isn'r enough power to keep her in high gear or overdrive isn't this a little back to front???

only thing they could recomend was to check & top up the ATF fluid and if that doesn't cure it then to leave it with them and they will order parts and try to fix it that way but any parts ordered & fiitted (even if they don't fix it will be chargeable - if we are looking at sensors etc. then that's not too bad (wouldn't knackered sensors show up a fault code) but if we are talking big bits like turbos or gerboxes then that's cost I can ill afford.

I need to get her sorted but at a bit of a loss

HELP

LOL, you don't need any diagnostic equipment!!! A paper clip and count the flashes of the engine check lights is all you need!

Don't get blinded by tech speak at garages.

I bet they only lobbed some redex in the tank and caned it up the road in 2nd.

No fault codes means the fuel pressures at the pump are ok, and the timing is ok.

I'd say its only changing down cos you got your boot in and its not reving, so the box thinks you're going up hill or towing a heavy trailer so keeping in a lower gear.

For it to happen so quickly I'd be looking for a blockage, either behind the fuel temp sensor, or the spill control valve, both have filters behind them. Are you not getting a check light when its pumping smoke out and you've got you foot down? This would point me to the injectors or somethng mechanical like a head gasket/valve. A compression test would prove the later, and I'd stump for some recon injectors next, they arn't a bad idea after 70k miles in my experiance. If that dosn't fix it then the fuel pump would be next, although a good used one would be cheaper than re-con'ed (especially as its hit and miss that anything useful ever gets done.)
