200tdi odd blue smoke issue

harry2012 · Mar 22, 2015

Had a good look over it yesterday and I've noticed the injector pump is leaking quite badly.

Looks like it's where the connector black joins the pump body. I'm assuming if this is leaking, when cold it could be letting a little air in causing the smoke issues.

I see the O Ring is easy to change. Anyone know where I can get the O Ring from?

If your Injection pump is leaking, take it to a fuel injection specialist to look at.

I very much doubt if that smoke is anything to do with the pump leak, have you put the right oil in it yet?

Agree with Turboman, doubt if leak has any thing to do with smoke,but that thin oil would.
My 200 smoked a fair bit and used some oil when I put it in my 90,came from landy that had only potterd about putting boats in and out of the water. After a year of normal hard work there was little oil use/smoke
Watched your vid again and pumping the throttle running light when cold will result in extra smoke.

I agree, my pump problems gave more of a bonfire effect with thicker grey/blue smoke that hung in the air.. this looks like burnt oil..

Have a read up on the o-ring I have read it can be done but have also read of it going very wrong for people!

Ps meant to say took the series 2 tdi out today for only the second time this year, smoked when started very light smoke for a few hundred yards and thats it pretty much clear, well as clear as a 200 can be, good 25 mile thrashing 80 down the motorway pick up an engine crane, ran very well.

The oil in it is exactly what Landrover specify though?

I haven't got the money for a full pump refurb which it might or might not need. £18 for a gasket set I'm happy to risk it to change the O Ring, if it works great if it doesn't then the pump needs a refurb and I'll have to fork the money out.

As I said it's a genuine 79k from new engine.

I checked the oil properly today and it hasn't used a drop, still sat bang on 'H' I did 70 miles in it today and it absolutely flies, it easily gets to 80 (on a private road officer) and apart from the initial blue cloud on first start which clears in 30 seconds it doesn't smoke at all, not even black smoke and no the pump hasn't been tweaked. I gave it a beasting today to get the engine working just in case it's glazed bores.

I'm now wondering if with the oil on H not N and the fact it's parked facing downhill for weeks at a time some oil is getting into the bores because parked outside my house facing downhill it shows as quite a bit above H (almost an inch above), I've also been told by a few diesel specialists that poor atomisation on startup can also cause blue smoke hence me wondering about the diesel pump.

As a test I've parked it on the flat in our car park tonight (I just hope it doesn't get stolen!) if there's no smoke it's purely down to being overfilled with oil and parking it downhill.

Its the injectors that do the atomising of the fuel.

Is it the viscosity land rover specify?
Mines always ends up on N even when its topped up to H.
Cant see how you park it making any difference.
Thrashing it wont deglaze bores, I recently saw a truck thats bores were so badly glazed it was unreal under 30k kilometres on the tacho, new engine time.

It's done a couple of thousand miles since I changed the oil and it hasn't used any.

I wasn't suggesting you get a full pump rebuild, just that you take it to someone who knows what they are looking at to confirm your diagnosis. Pump leaks are often difficult to identify, hot diesel runs and crawls everywhere. They will also supply the o ring if you want to fit it yourself!

I still think you are in denial about this oil, being on the high mark will not be a problem. What you should do is change the oil for mineral oil, you can fill to the normal level then.

If you re-read the thread, you will find that several of us posted about poor fuel atomisation. As you have had the injectors serviced, that is unlikely to be the issue.
