1.6 JX with blue smoke.

[Custom & Bespoke]

Hi there,
As the heading says our 1.6 jx now has a lot of blue smoke on start up and fails to idle, initially it struggled to start after being standing over night and I found the only way to keep it from stalling was to use the cold start lever and then push it in after a minute or so, then we were using lots of oil so have replaced the turbo which was planned any way but this has had no effect on the smoke. I have read other posts on here regarding similar problems relating to petrol engines which suggested valve guides or piston rings, would the same apply to the diesel engine ? I am planning on having the timing checked first and then compression, is this correct ?

[dave friday]

Well checking the timing is a good idea and checking the compression will give some idea of the condition of the piston rings.
Is it still using lots of oil?

I'm now unable to keep it running long enough, it has new oil,filter,air filter etc as all were done when changing the turbo.

[dave friday]

make sure that the wire that goes to the fuel pump[fuel pump solinoid] is on tight.
is there lots of white smoke on start up?

[Custom & Bespoke]

Only a small amount, then I have to press the accelerater to keep it from stalling, if I do back off the blue smoke turn's white for a moment but I would have to catch the revs before stalling.

this should help (and save my fingers)

Many thanks for the link, its basically backing up my worst suspicions

[dave friday]

did you replace the turbo yourself?

[Custom & Bespoke]

Yes I did and relaced the oil feed pipe at the same time and carried out all the required priming etc.

[dave friday]

I think that posting the history of work done on the engine and how the van was running when you got it, and how the performance deteriorated would help us guess what is wrong.

The van had been running fine during the summer last year, I then had it on the drive for a few months without any real use but kept it turned over, when I started using it again I noticed the injector pipes had a leak so they've been replaced, shortly followed by turning over but not firing so the glow plugs have been changed, all was fine, starting and driving ok then it started to take longer to fire up combined with alot of smoke on start up and stalled when it did. I also found that using the cold start helped it tick over initially but I had never had cause to use this ever before.
Once running it would drive fine but when left again for a few hours or overnight the same would happen once again, ( at this point the excessive oil consumption was realised )its been suggested by someone locally to me that the bore's are filling with oil when sat still for any period of time.
Also, previously ( 20,000 miles ago ) in its service history there is a receipt for removal of cylinder head, replace damaged valves, guides, seats, machine head, new oil pump, crankshaft and pulley, reassemble with timing belt, head bolts and gaskets etc, this has all been carried out before I purchased the van and since we have owned it we have travelled to Spain a couple of times and Italy and never had any running problems at all.
Many thanks for reading my posts and replying, Darren.

Ta,was the turbo you fitted a new/ re-conditioned one?
have you got 9 ish volts at the glo-plugs?
Have you drained the water from the fuel filter?

this sounds like the timing belt snapped prior to these repairs. how long since the timing belt was changed, 5 yrs max between changes, have you got water going in to the fuel tank, change the fuel filter, check the injector tips you could have one missing in action, retime it, its up in the wiki. you don't need it running to set the timing. youtube it, there are lots of how to's.

did you change the turbo because it was revving its bottom off, and running on its engine oil?

Turbo was changed thanks to a local garage being 95% sure it was on its way out due to oil usage etc ! Fuel filter was replaced 3000 miles ago at service, should I change it again ? I have not removed any water from it as of yet, I will check the injector tips tomorrow, could you tell me exactly what I 'm looking for please as this is all new to me ? I was meant to have someone coming to take a look at it for me as from last thursday but they mucking me about with times which is no help to me, I'm not really sure if this job is going to be one Ican do myself

the injector will look like this (link), if the tip/s are broken you will be able to tell, Im going discount the turbo because its the easy thing to point at (for now). so check the injectors, set the timing, change the fuel filter, about a £5 get a mann one offof brickwerks, you can get the injectors refurbed in hull at hgl.

then were on to the injector pump and turbo, but you could get a replacement engine running and complete for about the same cost as replacing both, avoid scene dealers and hit the scrapyards.

get your rubber gloves on and get your spanners mucky, your not really doing out that'll make it any worserer.
