Vito 110 Black Smoke Help Please

[rich17865]

Hello, as this is my first post here, I hope I have put this in the right place.

I have a Vito 110 2000reg.

I have just had a NEW engine, turbo and 4 reconditioned injectors. It does drive lovely, but when you give it the beans, huge clouds of black smoke come out of the exhaust. It makes no difference if the engine is hot or cold, and is not using more oil than should be expected.

I am aware that this is an overfuelling problem.

The place I had the engine replaced at have turned out to be a bunch of untrained monkeys.

What have they forgotten to do? Please bear in mind that everything is new so should work fine.

I have no interest in taking the van back to them as they seem to just break things that have nothing to do with the job in hand.

Do the new injectors need to be set up in the ECU? As I already know that they only have a fault code reader and not a proper STAR setup.

All help greatfully received

You had new engine instaled... Was it complete with electrics? Ecu? There are lots different models and versions so I under how was it established what engine to put in.

Other thing is... If it wasnt complete then maybe air leak or old EGR or damaged MAF and that can create big black cloud in a back while accelerate. I would suggest to change then but before that make sure you have all right configuration as well as do proper scan by STAR machine - only STAR - dont go anywhere else to be scanned by some crapy scanners....

Complete with electrics? The electrics were already in the van, I simply had a replacement OM611 engine. There is No MAF, no boost pressure or air leaks. I might give a replacement EGR valve a go.

I am almost certain that there is a problem with the setup of the injectors.

I would be looking at vacumm at the EGR first then the EGR itself.

 

[rich17865]

how would one test the vacuum for the egr valve??

 

[BlackC55]

Put a vac guage on the pipe to the EGR and see if it holds vacuum and Vice versa.

 

[rich17865]

oh, and without a vac gauge?

 

[BlackC55]

With your mouth then!

 

[rich17865]

more to the point, can the van run perfectly well, if the egr valve is faulty? It starts and idles well, pulls like a train.

Just the black smoke?

Hi Rich17865.

You are located in Crewe. So are Crewe Engines. I know nothing of them other than their adverts for rebuilding/fitting Mercedes engines.

If you are struggling I'm sure they could help. For money of course!! Not sure of any Indies in that neck of the woods.

Good Luck.

It was Crewe Engines that fitted the replacement engine and parts.

They couldn't get it running properly, so I had to take it to a MB dealer, who told me that Crewe Engines had put it together wrong. MB assembled it correctly and it would run normally. I am still seeking compensation for this.

Crewe Engines have also broken the following parts when fitting my engine,

Upper and lower inlet manifold, brass studs broken.
O/S Headlight, vac pipe snapped off (then glued back on filling headlight with superglue).
Rear oil cap, smashed.
Oil breather pipe not attached leaking oil onto exhaust manifold.
Turbo oil supply pipe incorrectly fitted fouling turbo wastegate actuator.
Oil leak that I cannot find yet.

I cannot say that this is all they have done, this is all I have found so far.

I can highly recommend that NOBODY ever takes even a diesel powered hairdryer there. They are incompetent, useless and don't have the correct tools for the jobs they take on.

I ignored the black smoke at first as I thought that it might be a bit smoky as the rings bedded in, but now I know that was not the case.

I have no interest in taking it back there as they couldn't put it together properly in the first place, so I have no faith that they could fix any subsequent problems.

Whoops sorry.

Thanks for naming them.

 

[rich17865]

no ideas what is causing the black smoke then? Nothing common that hasn't already been replaced?

 

[rich17865]

I have cleaned out the pipe from the manifold to the MAP sensor, it was blocked with black stuff, still no joy though.

Anybody got any ideas before it goes to the injection specialist on Monday?

map sensor calculates fuel quantity. you EGR valve not dense. check vacuum general and vacuum control EGR valve.

I have had a look at the EGR valve, it does move, about a 1/4 of an inch, is that normal or should it be moving more than that?

please do "diagnostic" and see a weight air

I have replaced the MAP sensor as it was producing strange outputs, problem almost solved, considerably less smoke now, but still some never the less, more than I would expect from new everything important.
