Oh, dont get me wrong. I do think the Elsbett kit was quite well though out. I am sure that it was being supplied with the wrong heatshield washers was what kanckered the injectors. It just goes to prove that someone who calimes to be an expert and even trades as such can make mistakes (or is just plain stupid!) Needless to say I won't be using the Diesel Service Centre in Peterborough again.
I do have doubts as to the effectiveness of the electric filter supplied by Elsbett. 180W of power is not going to heat the fuel up quickly and even when it does heat up, you still have cold fuel in the IP and lines to the injectors. Perhaps the Elsbett nozzles would have coped with it, but not after have the combustion gasses and materials forced back up around them due the dodgy heatshield washers.

A few things to consider:

1. Be careful which oil you use. Veg oil can be quite acidic and will eat certain fuel and injector pumps. Bosch are OK apparently others dissolve!
2. 100% oil can go really thick in cold conditions, a bit like wax. If you want to run 100% you'd need a pre heater.
3. The longer molecules in veg oil will tend to clogg injectors after a while. STP injector cleaner seems to work.
4. It is legal as long as you pay duty. If they catch you not paying duty and you can't prove how much you've used they will back date the duty over the full mileage of the car!

Hopefully the kit will solve all of these problems, however I run my standard D5 on about 30% veg oil and it works fine and gets round the above issues.

Sorry just saw all the other answers!!! doh!

What problems would you not have expected given that the kit was never installed correctly/completly?

well leaking injectors for one and two the carbonised injectors caused by what looks like the wrong sealing washers for the injectors/engine - fitting new tips to the injectors is a boys job and i suspect that there is something wrong with the new parts supplied and it looks like the wrong sealing washers were supplied which caused even more problems BOTH of these issues have nothing to do with the bit by bit way this kit was installed.

The incorrect sealing washers that caused the leaking and carbonisation were supplied by Diesel Service Centre in Peterborough, not Elsbett.

Just to add..... the installed Elsbett kits I saw were professional installs and hadn't given any problems. One was the installers own vehicle (the Defender)

Well i read it that the washers came from Elsbett but you could be right and they came from the Diesel Service Centre in Peterborough. But if so why did Elsbett not supply these parts? The injectors were leaking diesel after fitting the Elsbett nozzles - they were leaking diesel not having sealing problems in the cylinder head - these diesel leaks are nothing to do with these sealing washers it would seem that there is a problem with the fit of the nozzles in the injector and no matter how tight or hard you tighten the nozzle nut these leak wont go away. I agree that a professional will have/should have less problems fitting these kits - or be better equipped and experienced to solve these sort of problems - doubly so if it is his own vehicle when the motivation to do the best job possible will be to the fore - but surely these kits should be almost idiot proof they are sold as DIY after all.

Apologies for any confusion. Elsbett just supply the nozzles and leave it up to you to find an expert to fit them into the injector bodies. Sadly it seems the company I chose to fit the nozzles in the bodies were not experts!

There could have been a problem with the fit of the Elsbett nozzles or it could have been the incorrect installation by the so-called experts or it could have been the heatshield washers supplied by the so-called experts.

I think it is most likely that the washers were the root cause of the problem. Having opened up the injectors it's hard to see how you could put them together wrongly. Measuring the Elsbett nozzles with a micrometer all the external dimensions match the Bosch ones to within a few thou'. So I'm still convinced that it was the washers letting the comustion gassess up into the bodies that caused the leaking and damage.

ok still confused these washers are internal to the injector and not external going between the cyl head and the injector

thanks

The washers are external to the injector body and sit between the injector body and and the cylinder head. They provide a seal around the face of the nozzle and the pre-chamber. The dodgy ones I was given simply didn't seal and left the whole of the nozzle face and bottom of the injector body open to the combustion gasses.
I'll take some pictures when my exchange set of injectors arrive....still hoping it will be today!
