Maybe Kev, but it was my understanding that diesel injection systems (like rotating things like pumps) relied to some extent on the fuel as a lubricant?

Hence, that's why I thought there was all the "Hoo-ha" about the worse lubricity of low sulphur diesel. Admittedly for this age, the fuel type would/should have been taken into account @ the component design/validation stage.


.....but the injector is at the combustion and HOT end of the cycle Andy.......the pump is just that afaik......a high pressure cold electro mechanical widget that won't give a monkeez about fuel quality.....naw....?

Naw Kev, when I had two injectors replaced by a local, reputable diesel specialist they drained the fuel filter and disected it to check for any evidence of metal particles from the fuel pump. Evidently it's fairly common for the high pressure fuel pumps to wear and as shcm points out these new low sulphur fuels don't help, hence why I religiously add 'Millers' with every fill of quality branded fuel..

I thought the fuel went through the fuel filter before it got to the high pressure pump.
If things are still the same as the old diesels, the fuel pump, also known as the lift pump, pumped fuel from the tank, to the filter, then the injector pump, then injectors.
If the injector pump churns out bits of metal, nothing will stop them getting to the injectors.

It's 'leak off' fuel that could end up in the filter...

It gets worse. Chased them up today and the garage phoned the "injection specialists" and were told that the injector pump shaft and body were damaged and unrepairable. They happen to have a reconditioned pump they can supply for £600.00 plus vat. I'm over a barrel and will need some anusol afterwards!

So........urr we saying that Supermarket fuel, when CAULD, is actually melting the bliddy pumps, mins......? Noo......we ALL know how difficult it has been.....always will be......nigh on impossible to convince SOME folk that Supermarket diesel is widdle. Now we are to try and educate them that even fuel pumps, pre any ignition exacerbations, are also being affected.....? Thank golly gosh I am a cardboard boax expert, mins.......lol.

Some times you have to take it on the chin when things go wrong.Most people are genuine and don't rip people off.
I would have seen it as a positive they had a spare one available,while not cheap it must come with a warranty,better than one from a breakers that could be on its last legs.You should be a happy bunny soon,just say Christmas is cancelled this year.

I suppose I have been spoiled by just paying servicing costs for six years and 91000 miles with the Rav.
If I think back to the days of the H reg Discovery - reconditioned gearbox and replacement clutch after 55000 miles, reconditioned steering box after 60000 miles and services that cost less than £600.00 were considered cheap - but I was working then and enjoying my first 4 wheel drive, until I realised that you have to be a mechanic to run a Land Rover product or a rich b******d.
I really can't see how my injection pump was wrecked and I can't help feeling some suspicion that I'm being shafted.
If I get to France and back, the Kia and it's 7 year warranty is becoming more and more tempting - and Toyota seem to have screwed it up with the new Ravs that are available now - need a change anyway.

I repeat what I said about the Kia 7 year warranty. You should speak to my mate about trying to make claims !

In what way have Toyota screwed up with the later Rav4s ? Curious as the 4.4 I have is far better than my old 4.3.

Correct me if I'm wrong Charlie, but I'm lead to believe that the new Rav 4 diesel is only available as an AWD in hybrid form. As a tin tent tower, I need 4wd, not for normal road towing, but anyone who has ever tried to tow a caravan out of a waterlogged field will know what I mean - also the weight of a SUV, with combined power and torque is necessary for the heavy and well equipped tin tents we like to spend our holidays in. The 150 bhp 2.2 diesel is just about adequate for the caravan I have and while the Lindop chip kit, set on no. 6, improves matters a lot, judging from the spec of the new Kia Sorento, I would be able to forget that I am towing 1600kg - and if I did want to stay with Toyota, the Land Cruiser is dated and almost Range Rover price anyway. I'd gladly go back to the Hilux, but her indoors found the cart-sprung rear suspension intolerable for her bad back. I know Toyota seems to be concentrating on developing eco and hybrid technology, but they really could do with a better product range or they'll end up like Ford - boring.
(I did Latin at school as well and anyone who has ever had the Nobby Stiles, or a sore arse for that matter, doesn't need Latin to know what anusol is for).
