i think the testing machines are mucho moolah

Have yu ever used one?

And how would you go about measuring the pressure and calibrating the exact quantity of fuel being delivered without one?

As I said, I don't know Bosch pumps, but the CAV pump was designed to be set up using a test machine, and there is no facility to calibrate in any other way.

no never used one.

yeah you need a test rig afaik. just saying that's why rebuilds are quite pricey.. they have to pay for the expensive test rigs.

Yes, they sell for ****loads, I have tried to buy them second hand a few times, but I wasn't going to pay thousands, I would only use it occasionally.

If you ever get a chance, watch them run up and calibrate a pump on the machine, it is interesting.

Not done any further investigation yet.

But this is the smoke on startup.

Looks more like oil in that photo..

Doesn't look to much to worry about, does it clear after running for a few miles?
Any thing too desperate will show up on MOT emissions, but it sounds like you have done pretty much everything.

One possibility is his bores may have glazed a bit, so it burns a bit of oil on startup.

This is quite common, especially on diesels that don't get worked very hard. And modern oils are so good sometimes that contributes to the problem.

Cure is simple, cheaper oil, don't change it so often, and a regular blast up steep hills wit a heavy trailer on!

harry2012 · Mar 18, 2015

Ah ok I have semi synthetic expensive 5w30 in it (what Landrover specify) might give it another change with some thicker cheaper oil.

Tbh it doesn't get used much nor worked very hard.

And yes it clears after a minute or so.

trax · Mar 18, 2015

if that's the only amount and it clears up in a min, then i wouldn't bother wasting time on it

lynall · Mar 18, 2015

So you are running 5/30 in a 200tdi engine, Im not sure if you mentioned this fact before?
They like old mineral ****, people are obsessed with semi and syn oils, I cant believe the amount of people who put it in old cars and wonder why they have problems.
15/40 is the kiddy, Ive been running it in tdi engines forever, change it every 5k and thrash the pants off it everywhere, it will run forever.

If only we had known this before

harry2012 · Mar 18, 2015

Sorry I lied it's got 10w40 semi synthetic in it.

And mineral oils I thought whilst might be fine for the engine aren't any good for Turbo's and the temps they run at.

I put 5w30 in my dad's TDCI transit.

Get some 15/40 mineral oil, just a regular turbo diesel oil like Vanellus, Total Rubia, any of them.

And do something to make it grunt, tow a trailer uphill, charge it up the motorway for hundreds of miles, fit mahoosive tyres and go to Pay, and Play. Whatever takes your fancy!

Your problem should clear up after a while.

Good quality mineral oils are perfectly good for older turbo diesel engines. When these engines were designed there were no synthetic oils, or rare as hens teeth.

TDCI is a totally different thing.

If you're right and it's as simple as that I'll buy you a pint in thanks!

Thanks for the offer, but no worries, hope it sorts it out.

I am pretty sure it will, I have seen this a few times, common on yard tractors that never do any hard work, just shuttle around a bit with a loader.
Cheaper oil, and a good day on the muckspreader seems to sort em out!

+1 on the bores glazing I work for a utilities company and some of the unimogs land rovers etc that have PTO spend a lot of time idling or not working very hard, I also have a 200 tdi that puff a a bit of blue here and there but mines done nearly 200k. As Turboman said give it a right good seeing to don't hang around. When mine does it I now just take it for a really long hill in a higher gear really make the engine work hard

tottot · Mar 18, 2015

Had an old neighbour who drove his 90 everywhere at fifteen to twenty mph in a cloud of blue smoke, don't think he ever got further than third gear and a more glazed engine you will never see.
Engine abuse I would say but you can't hold that against a man who popped his clogs driving his landy around the fields.

I will let you off this time

10/40 still quite thin for such an old design motor.
Trucks all have turbos and have been running mineral oil since the dawn of time and have only recently (2006) gone over to synthetics and they are 50 to 70k oil change intervals and they all without exception get thrashed!

No, you cant!

Wouldn't mind going that way myself, hopefully not for a bit, though.

Agree completely, mineral oil, regular oil and filter changes is the way o go with older diesels, either na or turbo.

As you say the synthetic oils are for highly stressed modern turbo engines.
