for the last few weeks ive been smelling a strong smell of diesel, ive had a look today & found diesel running down the sump & dripping onto the floor, it seems like the no3 injector is weeping, is it just a matter of tightening or something more sinister as i know no3 is the one with a chip in it, i believe a special socket is required which i dont have, any help would be appreciated. :y oh & the little rubber pipes look o,k.

That's no4 I believe. Try nipping it up first see if it seals.

cheers mick, its the one with a wire going into it so i guess its the expensive one ;), i`ll try & nip it up if i can get to it :D

you might need to replace the leakoff pipes if you start the engine and shine a torch on it you should see it easy fix or nip up the nut its a 17mm spanner.
No 4 is the sensor
-
I rekon its more likely to be the leak off pipes than the injector. If the injector is leaking, then you will see a pool of diesel at the bottom of the injector with bubbles of air escaping from around the thread.
-
Should be leak-off pipes or the injector pipe.
-
I've got a length of leak off here if you need a bit to try Should be enough to replace the sections between all 6 injectors but there isn't enough to go back to the pump as well.
-
cheers chaps, i`ll take a good look at it tomorrow, is the leak off pipe anything special or will vacuum pipe do the job [if you know what i mean], & thanks for the offer welung but it might be a bit far to travel for a bit of pipe ;) :y
-
I was thinking Royal Fail rather than a visit ::) Different to vacuum hose as it needs a certain chemical resistance with carrying diesel ;)

I got some from my local motor factors, you need diesel leak off pipe, braided rubber. :y

-
any local m/factors or halfords costs less than a tenner simple to do you get enough for all 6 in the pack. :y
-
cheers once again chaps, i`ll go visit my local factors & do the lot as the stuff on it doesnt look like its braided anyway :-/, ive only just replaced my fuel lines as they rotted at the back & leaked & now this >:( aww bugga >:(
-
here is the update, ive changed the leak off pipes & cleaned it all down, but i still have the leak from no4 & no5, so any suggestions what to do next as i dont have the special socket for the no4 injector :'(.
-
where exactly is the leak. :question
is it below the leak off pipes on the ridge
-
yup it does seem to be where it screws in, please tell me it just needs tightening :-/
-
Are you sure that this isn't already-leaked fuel sitting in the recess?
-
very sure sethsmate, i cleaned it right down & it was bone dry, i then started it up & after a minute or so it starts seaping out, ive tried tightening the fuel nut but it seems to be coming from lower down. im pretty sure its from where the injector screws in :'(

Can't remember what size, I think it's 27mm (Sethsmate will know for sure, he also has the torque settings).
I had to bevel the edge of my socket on a bench grinder. Even though it was a thin walled socket, it would not quite get far enough into the recess.

if the injector was loose you would see bubbles around the threads you won't see unburnt fuel.
ive got a sneaky feeling it the injector body thats leaking to tighten this the injectors have to be removed on the above link ignore the cleaning side.
on the photo that shows the spliting of the injector you tighted the only thing you will need is the 27mm socket and long screwdriver to unplug number 4.
dont worry its easy good luck :y
-
Injector to cylinder head torque setting is 65 Nm.
-
thanks sethsmate, anyhow i bought the 27mm socket & removed the injector, tightened it all up & replaced it, had a hell of a time plugging the wiring plug back in, as a result one of the wires snapped >:(, but for the time being i twisted it together just to test,,,,,the result is its still leaking, looks like its coming from where the wires go into it, im thoroughly poxed off with it now as it dont look like its going to be fixable, anybody got a spare no4 injector?? :'( :'( :'( :'( :'(
-
I've got a complete tractor in 'For Sale' section. (Posted in December) with new No.4 injector.
A new 'un'll set you back upwards of 200 bucks if your existing one is shot.
-
cheers sethsmate, if i could afford it i would have it, as it goes ive just got hold of another injector for £20, do these things need any setting up or just screw & go :D.
-
just screw and go as longs it came from a meega :y
