I think the running issues could be down the these outer injectors..

engine warm.

3 mins at idle and 15 seconds at fast idle.. I cant imagine the 1 and 4 are doing much work at all!?


The measured and desired fuel pressure values follow each other well.. which may mean the HP pump is ok.. and the LP too.

Is that from the leakoffs John?

They do look a bit uneven...

[jgra1]

yes Jim. . 1 and 4 are just drizzling
think I begin the engine removal now and will see what to do about the injectors.. quite sure they are the issue with limping and cutting out..

[jgra1]

Some progress during a busy weekend.. the van has been extracted from the engine/sub! Pic shows the aftermath of this.. (Van was llifted off and moved backwards, now the mechanicals are getting carried to workshop)


The van juddered badly in reverse, and so I suspected I would replace clutch, and cambelt (etc) and also there was a possible nasty driveshaft knock and ! a bad wheel bearing - all made me decide to remove the engine and subframe..plus I wanted to examine chassis closely and make some room to work underneath for welding..

I made 3 discoveries whilst this was happening..

The rear engine mount is toast.. the nearside driveshaft also has some movement, and the rubber flex pipe downstream from MAF is beyond a joke, split at every concertina ! I can’t imaging the ECU coping well with this unknown and major air leak just after the MAF….







Chaps - The Intercooler, and it’s surroundings, are very black..(I wonder if I can test the IC for leaks?) The cause of the black slime though … turbo seals or egr or both (did one cause the other) ?

More pics as I go

As of Sunday eve, the hubs, struts, driveshafts and the sub are all separated and block has had a wash .. and I have a bit of room to work again ?:)

You sure that engine crane's big enough???

I like the novel 'release agent' just peeking into shot at the bottom of the pic....

Image not working again John - Firefox, Chromium and Arora.
Logged into Google on the first two.

[CitroJim]

Not working for me either FF on Ubuntu..

[myglaren]

Images in The Independent are hitty-missy in Firefox today but OK in Chromium.
The leakoff photo is fine but the later one inaccessible.
This is with Linux Mint.

thanks all..

erm
will have a look tomorrow..

removed injectors, starter, 2 aux belts and cam cover tonight.. was expecting a locking hole in the starter area but nada.. however, there is one on the back of engine !
found the timing alignments but left undoing the crank bolt until tomorrow..

the vernier cam is all the way around against the stops, and there is evidence that it has not always been in that position..
cambelt looks ok but will change it anyway..

Maybe when last changed it was not done with due care. Timing may be a tadette off as a result...

Always good to have the vernier as near to mid-travel as possible John...

[jgra1]

my thoughts too Jim...

attention turns to the turbo and injectors,

and the pile of hard baked oil all over the offside engine bay, engine .. even behing the cam cover!

I am guessing a turbo rebuild is well beyond my capabilities, and will cost a fair bit.. same for injector cleaning...

I believe you can get rebuild kits for the turbo John, with everything critical already done... I think you get a new core which is transplanted into your casings so that's well within your abilities...

Injector cleaning definitely best left to the pros... They have the kit and test rigs to check the spray pattern and so on...

[jgra1]

thanks Jim..
(can anyone see the farm pic now?)

injectors can be sent and done for £22 each.
this is looking a very pricey job :O

DMF inspection soon... (can i just change the clutch if the DMF looks ok, i.e. leave it alone) - removing the box in the future isnt a big deal..

[CitroJim]

Oh yes, can see the farm picture now John! That's a lovely way of lifting an engine out

I'll have to leave to others the DMF question but is it not a good thought to replace it with a solid kit whilst you can - to avoid trouble later?
