Transit woes

[Ivory55]

Hi, on our way back home from holls I noticed black smoke from exhaust under load. Looked on the net and it pointed towards egr valve. A lorry fitter said take it off and clean it , got nothing to lose if no good get a new one. Have tried cleaning it no good, so put new fuel and air filter plus new egr valve on also brought some millers additive from halfords for the fuel and put that in the tank. Just been on the Italian tune up for 1hr 20min and still black smoke, it's not missing and ticks over ok. We live in Norfolk so a lack of hills so kept revs high all the time to generate heat. How long should it take to clear crap out or any other ideas welcome. Cheers ivory55

My 2007 mk7 work Transit used to spew out soot after long periods of light load running. A good thrashing sorted it out temporarily. You could rev it flat out momentarily and it left a big black patch on the road!
It never failed MOTs for emmisions though!

The van did have an EGR valve fail during the first thousand miles, but that caused a massive drop of power as well as the smoke.

Hi, the lorry fitter said they never have trouble with their parcel vans as they are thrashed, just new clutches. I took it out this morning up and down ders by pass then down to Lynn out to fakenham back to Heacham up and down ders by pass again and home. Still black smoke under load, am I expecting it to clear through to quick. It used to run clean. May be it's the new sainsburys diesel , ha ha. Ours is a 55 transit 2.4 engine. Cheers ivory55

Is the solenoid part of the egr valve or seperate? could be the solenoid or pipe from it to egr. (Had the same problem with a 406 once, fan belt came off & hit the small vac pipe to egr knocking it off, took awhile to find it).
You would also get the same symptoms with a blocked air intake or filter.

Hi, I put new fuel and air filters on. The old air filter was fairly clean. I have no warning lights on dash, I put a rag in to the manifold to clean out any muck there. Which there was. When I took it out I kept in 4th at 60mph which was 3500rpm or 3rd in the slower areas to try and keep it hot to burn off any crap. Cheers ivory55

Pointing towards the solenoid or vac pipe then. Is it down on power? if so turbo wastegate is also a possible.

I have a X-type jag 2.0d (mondeo tdci engine) that used to smoke on load, it had a new egr valve at 75k because it blocked, still ran smokey so I removed the egr and cleaned it but I also removed the inlet manifold and that was full of sticky black residue from the egr. Cleaned the manifold, cleaned the egr and blanked it off (vacuum egr so no sensor) now no more smoke at all and 136k on the clock.

Worth a look at manifold and see if you can blank it.

Mike.

PS it went through Mot with blanking plate in place..

Yes, or if vac operated just disconnect vac pipe and blank off at vaccuum side to maintain vac for brakes etc.
Trouble is a lot of Fords have electric stepper type & we don't know which type this one is?

 

[taffybloke]

If its electric it will have a couple of wires plugged into the egr. If vacuum just the vac pipe. These egr's do clog up the the inlet side of the engine and this could cause the power loss and smoke

Hi, it's got an electric connection on top and a small rubber hose as well. Cheers ivory55

And some have both, if the solenoid is built into the valve, which is why I asked the question.

If you are not sure perhaps a photo will help?

Sorry, posts crossed. OK, try disconnecting the hose & blank off with a bolt or something to maintain vaccuum.

Check the wastegate is not stuck and you do not have a leak on any intercooler pipework black smoke = to much fuel/not enough air BUT they do get sooted up if driven slowly and need a good booting to clean them out .

Yes I suggested that earlier. Difficult over distance isn't it. If it was here it would be sorted by now.

Hi, the boss only allows 50mph normally . As she paid for the van and I am the driver I do as I am told. So about 2300 rpm is the most it would do on open road, guess that's not enough heat to burn stuff off. Ivory55

You dont really need to burn it off as such. If you find the cause & fix it you should notice a difference straight away. Try the vac hose first & see. Also I note you fitted an air filter but is it possible that the hose from "outside" to the air filter may be blocked/ squashed? I've seen a few with a carrier bag sucked up them.

It's been pissing down all afternoon so not been out there, Friday will be the earliest I will get to it now. Thanks for all the pointers. Ivory55

No problem, I've sent you a PM.
