Hello JohnE

Could this come into play re your bad fuel from BP????

Again i like it when like minded people are about.
Andy for yours its the 4d56, (got an upgrade from 4d55)
I had glow plugs go before in the old motor the only way it would start was with the farmers friend Aerostart. Then had a bugger of a time getting the new ones to work, mine are 12volt and I was sold 6 volt, they burnt out in a week. But I will take you advice on board and check them, I didn't think of the glow plugs.Now that I think of it they are the plugs that came with the motor. See an electrical fault the last thing you look for in a diesel.

I don't know if the fuel mixing was the case with the BP fuel but I do know it is rubbish for my vehicles, in both diesel and petrol versions. Bad smoke with the diesels and , even though I never checked it, I don't think the economy was there.
I had a bad run with fuel years ago from an independent shell outlet, the paj started runner rougher and rougher. A mate of mine had a shell outlet too, I got him to look at the car , in his mechanic hat, his estimation was I had been using a cocktail he reckoned that was al the rage for diesel. I changed the fuel filter nad ran a bottle of injector cleaner through and it fixed the problem. I only bought fuel from the one place. I cut the fuel filter open it was caked with a reddish muck that was so thick it was a wonder the paj went.
The petrol I tried there stuff in my 'project' car my 5ltr HZ wagon( I'll finish it one day) been fixed to run on unleaded, it pings driving out of the driveway of the petrol station even their high octane stuff does the same.
Even though their was a post about avoiding the high enders in the fuel business, I still go to the Mobil here in Lismore the fuel quality is good in petrol and diesel.
But gettin back to the original post was the smoke problem sorted out, is it rings is it turbo oil seal is it a clagged up intercooler, or is it simply bad fuel.

Update....

Pump timing was out, not by much, but a little.
Went down a few hills and played and no smoke...

Intercooler is clean as is the intake pipes.

So i'd say Fred Smith Automotive was on the ball again.

Now..... it starts smooth and clatters nice like it should... it accually sounds like its retarded as it pings more...

It was just a suggestion [img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img]

A boke in my home town was caught putting kero in his tanks when he had to get rid of the old kero pump.
