Last friday i started to smell diesel exhaust fumes inside my vito 108cdi minibus. took to my usual garage who said they could smell but not sure where from.Took it to get exhaust checked all over and found no problem.

today took it to our mercedes garage. they just rang and reckon the pistons are blowing by the seals on the injectors..(im lost) they need to take injectors out but reckon 9 times out of 10 they break, so i will nedd 4 injectore, seals,bolts, a pipe, a rocker cover and a gasket totalling about 1500 + labour at 75 +vat !!!!!!!!

its using a bit more diesel but it doesnt seem to have lost power or if it has it aint much. r they taking me for a ride cos a few people are telling me it seems a little odd....


hope u can help

This might sound strahaange but i had same problem with my van when i got it , but what had happened was the rear window was smashed to get at some tools, by some tool, and the new glass wasnt fitted properly, i only noticed after the first time i power washed the van and i saw a pool at the tailgate.Not saying that you have the same problem but i'd check all the window and door seals for leaks.

had similar problem only now and again i could smell fumes .when it went in for a service they changed injectors because they were faulty. when i got the report back on the sevice they changed the injectors and the seals .if your injectors are loose they will blow carbon and it sits on the head like concrete, this is a good indication of loose seals. How clean is your motor , just check above rocker cover there is a ventilation pipe that runs into the turbo intake pipe maybe loose this will blow a lot of fumes. injector replacements are not cheap. check these firsts or second appinion. the mechanic told me they had another vito in there with leaky injectors they had to take out the head to machine the carbon out i hate to think of the cost. mine cost $3500 for three new MB injectors plus service ,and labour costs mine also had small amounts of carbon around the seals. expensive repaire job.

now smell is gone .

hope this helps

I also had the same problem, mine was caused by the injector nozzle washer failing. The carbon does end as hard as concrete! £5 for four new washers & new injector clamp bolts.
I also suffered with one of the other injectors being seized in the cylinder head, broke the cam cover & damaged the injector trying to get it out.
The van is now on ebay (item 4643264573) for spares or repair. I've replaced the van with a 110CDi. Should've got one of them in the first place, it flies compared to the 108CDi. LOL

smell in cab

I bought my 108cdi through auction with 100000on clock for which i thought at the time was pretty cheap. But i to noticed a smell coming back into the cab and put it in for service to find i had a leaky injector which with petrol and oil mixture escaping and forming like a resin which has incased all my injectors and the only way to get to the injectors is to hammer and chissel all the resin away. I cant tell you the outcome yet because it only went in yesterday, but by the look of some of the costing above i dont really want to know.

I will keep you posted

hello same problem

you might be lucky johnno it might be loose injectors , the cost goes up if you have faulty injectors . Very common for injectors to leak around 100000Km . This is more or less when the major service on the van is due.they come loose due to vibration hard driving heat , every day running common . Good investment buy an inspection telescopic mirror and visual checks at intervals . they can come loose if not torqued up properly. Now you know why dealer warranty runs out at 100000Km for all cars ,major service. But once fixed it will do another 100. Company's change there cars, trucks when they get close to there warranty running out especially fleet cars.

Problem with injectors ?

Hello from France !

Sorry for my very bad english! I have a VITO 112 CDI (260000 kms) and i started to smell diesel exhaust fumes inside. I think it's a problem on injectors too.

I would like to know if one of you already changed these seels? Is it really difficult????

 

[montymole]

It depends what you consider difficult, I would class it as challenging especially if the injectors are coked up (not cola ..). The below is my experience with a 2.2 CDI 1999. I would say only do this if you have some previous on other engines as these beasts are complicated and are by no means a beginners engine ...

A trick I found to easy the pain was to run the engine (as I described previously somewhere here) with the top of the inlet manifold off the vehicle to full running temp.

When it is hot the hardened black coke magically turns into something approaching black chewing gum and is actually possible to remove cleanly if done before it cools and hardens again.

On the injectors there are actually two seals, a O ring and a copper washer. Put a new copper one on always, with regards to the O ring almost always destroys when you re-seat the injector and makes it much harder to seat and torque up, I changed a couple but stopped.

Use anti-seize paste on the body of the injector and torque the bolt correctly when refitting. Make sure you hold the pipe union nut on the injector when removing and connecting the high pressure pipe (put the pipes back in the same order as removed), they crack and leak if turned too far ... I know just ask the kind AA man who towed me home leaking diesel ...

A warning, make sure you clean out the hole for the long screw that torques down the injector, if it is full of crap the torque will be fine but it won't be holding the injector down !!

Tip: If you choose to replace these screws, use an old clean one and with an angle grinder create a makeshift tap (i.e. cut slots perpendicularly along the threads) that the crap can cling to and be removed quicker add WD40 to the thread to pull out even more in one go.

My final comment, clean, clean and clean again. Did I say clean, then scrub. From bitter experience if the screw thread or the seats or the injector hole are not clean you will be doing this all again very shortly (in my case less than 500 miles ...)

I have a 2002 108cdi with 99k and it doesn't start off the key without easy start or bumping but when it's running it sounds and drives perfect ? Was told by mercedes that it need 2 new injectors but just spoke to a guy who said it more than likely will just need the injectors to be resealed

If they did just need to be resealed would that caus it to not start ?

Any advice will help thanks

unfortunately your question is a bit like "how long is a piece of string".... any answer may be correct but it might as easily be wrong.

its not likely leaky injectors, unless really bad, would cause the starting problem but then again.. it might........ faulty or crapped-up injectors would be more likely.

If you decide to go the repair route.... try [email protected]...... you will also find him on ebay...... they (and others) are specialists who come to you, clean everything and remove the injectors... they the recut the mounts and machine the seats for new seals... then rebuild and test everything....... at around £450 (last time I asked) its cheaper than merc or most garages and reports indicate its a better job....... they are going to offer full injector cleaning and servicing as well but I know no details at present.

hiring the kit to do it yourself is over £100 and the chance of causing damage is high.......... yes I know people who've done it themselves without problems (VERY rare without hiring the extractor and seating tool from hutsons) but I've also had many more who have broken an injector or got swarf into the engine and needed massively expensive repair work.

given the money (and I have very little) I would, personally, get the expert and have everything done in the day with no hassles.

Ok thank you for your reply

When mercedes quoted me for the job the quoted £140 each for the non mercedes injectors + vat so £280 + vat which equals £336 and said it would take them 2 and a half hours to fit them @ 48.50 per hour so roughly £140 so total is £476 roughly of what I've been reading on here that sounds cheap ?

What do you think ?

 

[Cribby1707]

P.s I take home £812 a month and have no savings so getting it right is a must for me

 

[[email protected]]

the price quoted seems more like the cost of an injector.... you can easily get over £400 labour for a full job...... I make no judgements.. I simply pass on other peoples comments and experiences.

my own traveliner had the injectors removed, stripped, cleaned and serviced at its last service.... by the last owner because of "black death" (I have the receipt from solihul for £800+ for the work).... its leaking NOW (under 1000miles later) because they DIDN'T recut the sealing faces (I've since discovered most garages don't do this) so the new seals... simple copper washers... have distorted very quickly.

as soon as I have the money saved (I dream of your income... I dropped from todays equivalent of 80k per annum to a little over a current £100per week when I was disabled out of the workforce 23years ago).... I will be getting the guys over to do the job properly

G'Day Cribby, most of us here know the feeling. I have used MB in '09 then did 2 myself in '11, once I re-researched this great forum. From many posts I have read, many workshops, including (??), will "discover" other problems and blow the cost estimate. Some shops will bugger the job because they lack the knowledge/equipment. If I had had access to a mobile specialist, recommended by several people, I would definitely have used that option. Here in Oz, we are very limited in our choices, so we have to do it ourselves (a very tedious job in this case) or cough up big bucks. I hope you get it sorted properly and relatively cheaply. May 2013 be good to you all, and thank you to the regular contributors for their valuable help and information.
