Injectors fully refurbished, they weren't leaking but were over fuelling quite badly.

Still smoking the place out on startup. Stumped and pi##ed off with it now.

As before the smoke clears once it's warmed up.

I have noticed at night you can see smoke in car headlights as it's driving but by day it isn't noticeable after the initial smoke out on start up.

trax · Mar 16, 2015

would you say the vid you posted had clouds of smoke?

harry2012 · Mar 16, 2015

Tbh the video doesn't show it well.

When I started it today there was loads and it hung around in the air for ages.

It never used to do this.

blackstrat · Mar 16, 2015

Probably no help to you but I had this exact thing (only much more smoke than in your vid) but on a 300TDi and it turned out to be a knackered injector pump..

grey hanging around in the air smoke is unburnt fuel to me. (it is grey and not blue?)

you running some decent fuel? not veg, and have you ever ran veg?

do you have any tools to test the compression?

has anyone played with the fuel pump?, it should have a tamper proof cover on it. (pic on this thread http://www.landyzone.co.uk/lz/f8/sluggish-disco-not-any-more-146991.html)

It's definitely blue not black smoke. And stinks like an old car burning oil.

I've never ran veg in it can't say for its previous owners. I've had it 15 months and really this has started since I took it off roading back in November. It's been serviced regularly the last time just before I off roaded it and it's done maybe 1500 miles since then.

It's only got 79k on the clock too, and I have history to confirm it's genuine.

I don't have a Diesel compression tester just a Petrol one.

How did you find out that was the issue?

Just checked the oil again and it's not really used any.

when you went off road, is there a possibility that water got in the engine

right well, if you are sure then it's oil.

some ideas to try

start measuring how much oil you are using over how many miles.

i'd pull the intercooler and hoses out and check for pools of oil. i know you said you disconned them, but your exhaust pipe would have oil in it and it can take a while for it all to be burnt off.

you need to find the source. is it turbo seals? check the pipes and intercooler for pools, or when running with it off have a look at how much is getting by the seals.

injection pump seals gone and it's mixing oil with diesel? crack off a nut to the injector and collect some fuel in a jar to have a look

also check and smell the oil in the sump, make sure no diesel is in it. especially since you said your old injectors were overfueling

Previous owner had turned the pump up lots supposedly for more power but when I reset it to stock setting (to eliminate overfuelling as cause of smoke) it wouldn't start, I wondered if it had jumped a tooth on the cam and gave it to local indy for cambelt kit and pump reset, it was them that diagnosed it and fitted another (used) pump.. smoke now gone.

It has a snorkel but I noticed signs of muddy water in the Air Filter when I checked it. I really hope it didn't, however whilst we were out laning it did randomly cut out twice, restarted straight away I just hope it wasn't hydrolocking.

Would a compression check show up if there was a bent rod or something?

I've checked the Turbo no discernable play and very little signs of oil in the turbo pipes when I removed them.

Injection pump is a possibility I'll check the diesel, is there any other way of checking it? I've ordered a timing pin kit so I can check the pump timing is ok.

If not I think I need to take it to a Landy specialist. Anyone recommend any good ones in Wiltshire?

lynall · Mar 16, 2015

If it cut out I would say thats pointing to pump issues
I had similiar fault where it would randomly stop, removed stop solenoid guts and carry on, fit new solenoid and fine for a few weeks then would do the same again, would also drop one cylinder and run on three again randomly, cure removed and rain fuel filter fill it with injector cleaner and refit, this would last for that journey and might play up again next journey or days later, all fixed when I replaced the inj pump.
Ps a second hand known pump will cost a lot less than any work done by an indy.

harry2012 · Mar 16, 2015

It wouldn't cost much more to get my pump refurbished would it?

Thing is unless I know for sure I don't want to waste money changing the pump when it might not be that.

guess at 150-200 depending on what's knackered. get it redone with viton for veg if it's getting rebuilt.

blackstrat · Mar 16, 2015

I had to pay 175 for a good used pump so may be best to get an Indy to diagnose it first to be sure..

lynall · Mar 17, 2015

Serious money to get pumps rebuilt close to 500 quid wont be unusual.
Obviously different diesel shops different prices, but the good ones will replace everything thats worn or going to cause hassle.
I reckon theres a good few hours work is stripping one down, sussing the fault, rebuilding it then testing it.

trax · Mar 17, 2015

that dieselbob reckons min 75+vat http://www.dieselbob.co.uk/injectionpumps.aspx might be worthwhile having a chat with them

but i'd be doing everything else in this thread first before getting it rebuilt

I don't know Bosch pumps, but to get a good recon of a CAV pump would be pushing £500 now.
Much cheaper, and I would guess corners are being cut.

You are right, quite a lot of time,parts, testing before and after, you need a test rig, and on an old worn pump almost all the moving parts will have to be renewed.

trax · Mar 17, 2015

i think the testing machines are mucho moolah

lynall · Mar 17, 2015

I did hear local place to me spent 50k on the kit to test common rail stuff.
Rochester city diesel are pretty good, old fashioned one man band.
