sluggish and blue smoke

[martinsealy]

hi,
bit worried about my 120swb 1995 has a 2.5 di in it
i have followed threads and cable tied open butterfly flap,
in the hope of reducing blue smoke when revving up, it seems worse?
i haven't done the peul pump tweak yet, if i do am i liable to lose engine?
it doesn't seem to use any water or oil worth noting and no leaks.
just this blue smoke, very annoying
it is very sluggish pulling away this is why i was doing the thread.
any advice as i need the van for work etc?

As long as the pump hasn't already been touched you 'should' be ok however, your engine might just be a smoker some are and a full disable of the EGR, not cutting the legs of the vaccum as per my thread.
I also put a new air fillter in at the same time AND upped the fueling. You also could have a pump that is already too far advanced in fueling levels.

Read this thread as well as my How to http://www.fordtransit.org/forum/viewto ... sc&start=0

The golden rule is if you are unsure then don't do it. The pluging of the EGR vaccum pipe with the ebay ball bearing also has it's place as does the blocking of the return pipe. How far you go is up to you. My How To thread is the simple way but not perfect for all people.
Totally removing all the air intake and cleaning it out until it looks new might well be a good idea as it might be so coked up that the blue smoke isn't just unburnt fuel as is normally what Blue Smoke is.

i think i'll give the pump a tweak and see if i get the response, pull away response up.
the engine has done 155k, it does have a slight "wobble" at idle but sounds as though all cylinders are firing.
could the unburnt fuel you mention be an injector? causing wobble?
how could i check this?
i was worried blue smoke was worn out engine.
how can i check the pump settings- any manuals on the forum. it doesn't look like it has been opened or touched. generally it runs ok.
will cable tieing flap open affect my cold starting etc?
soz for all the points but really am worried

It might be that your EGR valve is FUBAR'd like mine was and full of oil which is then also being pulled in and burnt. Try blanking the line from the oil filler and see if it stops smoking ?

Unburnt fuel is too much fuel going into the cylinder, it has to go somewhere, unlikely that an injector is putting in too much fuel as a blocked injector is more common. Having said that you might have three blocked injectors and one good one, which would cause a wobble. Use a injector cleaner additive in the fuel.
Blue smoke could indeed be a worn out engine, too much oil in the engine is the same symtom as there is a point at which the oil has to go somewhere. Rough idle will be a fueling issue or possibly a timing one, when was the belt last changed?
Many people complain about smoke when they are nothing like the Batmobile, but there is a limit to what is acceptable and what is not. I have seen very new cars billowing smoke under acceleration (TDCI's mainly) which can't be correct but I can't see your van.
There are no settings as such on here, the correct way to set the pump is to get a Deisel Pump Specialist do it from scratch with whatever flow meters they use and that is NOT cheap.

The Cold start 'might' be effected but until we get the real cold weather you won't know, (cold start doesn't just mean starting from cold) but if you have kept the connecting rod as I said in the thread you can replace it in minutes.
It is all a trade off as the system was designed to have a variable air intake and you have it now set on full...but under full acceleration the flap opens to full anyway.
Think about where the vaccum starts, it is the oil filler cap and oil vapour will get sucked up and over time it will clog up the pipes and EGR unit itself, as Kapri found his was FULL of oil, now due to how the EGR recirculates the gases, if one part of the circuit is full of oil, where will it go? back through the system and ultimately down the exhaust pipe and so you WILL get smoke because of this.
