Hi,

I've read Brian A's probs with his C220 taking in air, wondering if my symptoms are linked, '96 W202 2.2 Auto Diesel continued running for a second or two when turned off and the key was taken out. Did this twice. Then as well as the over-running started stalling 2-3 secs after starting engine, re-starts immediately from then on no probs until turned off again. No rough running or any other different characteristics.

Haynes says Solenoid Stop Valve but reading the other posts mine may be on a vacuum. I haven't looked for air but no symtoms of that problem yet!

Other then checking the fuel lines for air any other ideas.:confused:

Whilst investigating the engine when I got it i took the top plastic cover off after exposing the top of the engine, there was 3 or 4 "dishes" with pipes in them, bleed pipes?, the dishes were almost full of diesel, is this right?

Thanks

Ellis

Using my limited knowledge of Mercs but after having taken off the plastic cover off the engine on numerous occassions I think that the dishes that you see are the holes that the injectors are in and that you should not be seeing diesel fuel in there.
It (and I know I'll be corrected if I'm wrong) seems like you have one or two injector pipes loose or broken and as a result are filling up your dishes.
The running on is probably caused by the fuel in the dishes being dragged down through the injector inlets until your dishes have run dry and the poor starting may be the result of your dishes needing to be replenished.
Whichever way you look at it I think you need to check that all the pipes leading to the injectors are secure and in good order,maybe they have just come off!
I'm probably 100% off the mark but it does make some sort of sense if you think about it.
Sorry I can't be of anymore help,good luck and wait for some of the brains on here to give it a shot.

Engine and Pump Dry

My local garage had a poke around, the engine is dry as is the pump although there is strong smell of diesel under the bonnet, still driving well once started, any other ideas anyone?

Fuel Dishes

This is my car with the black plastic top off.
Are these the dishes you were on about that were filled with diesel?
The ones at the bottom with a silver pipe going to each dish and all linked up by black pipes?

No!
These are the injectors and either they are leaking or the leak off pipes are.

This is the reason I posted the picture Dieselman so that we can confirm whether or not these are the dishes in question.

It doesn't matter, there shouldn't be any diesel anywhere. No wonder it smells, evaporating diesel is eye watering.

BrianA,

Yes these were the "dishes" I was talking about, could this be causing all/some of the symptoms the car is exhibiting. I suppose getting them done will at least stop the smell of diesel.

What does the sponge do?

I spoke to Ray at S&R in Formby who seemed to think it was a pressure problem anfd that my car is on a Lucas pump. I'll probably take it to him after Christmas, any ideas on a price for having the soft leak off pipes done?




Thanks

I think Dieselman wil have something to say about this!
Take the black plastic cover off,clean any diesel fuel away replace the air intake to inlet manifold pipe,turn the engine on and see if you can see where the fuel is leaking from,then take it from there.
You may have to clean fuel away from the injector housings and restart a few times to find all the leaks.
Phone your nearest MB dealer for a price on replacement leak off pipes they shouldn't be very dear but the first thing I would do is tighten any injector pipes (the metal ones) and check that all leak off pipes are nice and tight and secure.
As for the Formby man saying it's a pressure problem via the Lucas fuel pump ask him how the hell the fuel got to where it's got without pressure.
I'm not aware of a sponge unless it's fallen out of the round black breather filter somehow.
Good luck.

I meant it as an information point, the pump that is, not the mechanic saying thats where the problem definitely is........:confused: apologies for the confusion.....I shall try the advice, thanks;)

You may need a few new clips on those injector lines, I'm only mentioning it because somebody pointed out that I did on mine, and when replacing them with new ones there was a big difference in where the lines rested, and where the clips should of held them. Also they do vibrate quite a bit.

BTW, sorry to threadjack, but this talk of fluid in the injector sockets reminds me that on the rearmost cylinder (six?) on mine, there is often found a yellow oily fluid. I'm not sure its diesel, it smells more like oil and looks very clean. The spill pipe is almost brand new, could this just be oil vapours collecting back there?

Just mop up all the diesel with a paper towel then run the engine and watch for leaks. The most probable cause is split leak off pipes.
As far as replacing them it's a bit like this.
Go to your local MB dealer or better still Bosch diesel specialist and ask for some leak off pipe. They will probably give it to you. Now go home and give it to your 3 year old who is trained how to use a sharp knife safely.
Sit down and have a beer whilst said 3 year old replaces the pipes.;)

Do replace the plastic retaining clips as loose pipes is what causes them to fracture.

Check around the injectors for any more leaks, if still leaking nip up the high pressure unions a little until the leak stops.

I can't see how fuel leaking from around the injectors can be related to the fuel pump as it's a...errr....pump! It just pumps fuel when required.

It sounds like unused engine oil.

Maybe you should try to get the oil into the filler cap only instead of just throwing it in the general direction of the engine next time you fill it.:)

As far as I know your car has an electric stop solenoid and it sounds like this is sticking. Often they can stick either open, shut or partially open.

Sometimes they are just lazy, which sounds like the problem you have.

If you have a clear pic of the pump I can probably locate it for you.

This has been mentioned by a mechanic so it's good to have a second opinion, appreciate the replies to all.

Are the leak off pipes secured by a jubilee clip type arrangement andis it best to ask for new ones whilst getting the leak off pipes? I only ask 'cause my 4.5 yr old is asking;) not me obviously...........:confused:

No clips, it's just a push on peice of pipe. You only need the knife to slit the old pipe so it comes off easily and to cut the new pipe to length as it will come as one long piece.
