Injector replacments

Badger · Jul 27, 2010

I originally posted this in the Engine section, but the tumbleweed seemed to be obscuring the thread abit, so I'll re post it here for some advice.

In my ever need to embrace my 19J now that the money for a 200TDi has gone out the window, i'm working on getting her engine up n running nice n sweet.

Last week i ran with some Veg oil with a 70/30 mix and she ran fine but was an absolute bitch to start and in my investigations to source the problem i noticed one of the injectors was ' leaking ' fuel mixture down the side of the engine. Removing the injector to ' have a look ' i noticed a build up of black ' crap' around the end.

Replacing it back in the engine, i then changed the fuel filter and checked the pump when bleeding the system, all seemed to be oki.

Swapping back to diesel only ( i was a little dubious of running veg oil again for the time being until a pump and injectors were replaced ) she now idles abit odd, as in miss's every 4th stroke with a puff of smoke from her in the cycle.

Reading up abit it seems the injectors need to be set at the correct height to work efficiently and im also sure i've set the one i took out, incorrectly.

I'm about to order a full replacement set of injectors and a fuel lift pump, question is, how do i set the new injectors up properly?

Cheers

why dont you gets your redone by a diesel specialist? they will set it up and sort the spray pattern etc.

worth a ring around.

True, but the idea of owning a Landy is to do the work myself if at all possible.

Without specialist equipment there is very little you can do to injectors. One tip I got from old Herbert, an old time agricultural engineer was to remove injectors from engine and leve them to soak in petrol for at least two days. Apparantly this process cleans them out just as well as any other system .

I understand some things are best left to the pro's, but i was hoping a simple injector renewal was straightforward enough with the clearances possibly already set on the injectors combined with the correct torque setting.

have you tried running some injector cleaner through them

confused.

you cannot 'set' the injectors yourself. I was suggesting a specialist to clean and set yours rather than replace for new... its cheaper that way.

I guess i was confused as well

'Setting ' the injectors was reference to buying new ones, apprx £108 for a full set, i was wondering if they need ' setting up ' or do you just simply replace the old ones and torque down correctly.

With regards to the old ones, if it comes in cheaper and easier to get them set up properly by a diesel tech, then i'll consider it rather than buying new.

Whichever way it is, they need attention as the 2nd one from the front of the engine is spilling fuel as well.
