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....

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.
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
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.
Am having problem with fumes in cabin and leaking injectors. top of engine full of hard coal like material . my mechanic is saying that it is oil that has been boiled dry from a possible leak in rocker cover gasket also needing 4 new injectors costing big bucks done 230k has anyone else found oil to be the problem
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????
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 ... 8-)
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 ...)
