Hi everyone Was just wondering did any one ever come across the problem I'm having with my 6830 it's putting diesel into cylinder 6 when parked up and when u start it It puts it out the exhaust I have had all injecter checked and they came back ok So was wondering can it leak in from return pipes Has any one heard off this before

Are you sure its diesel ?
Be careful you don't bend a rod with liquid on top the piston

 

[David818]

Yeah its definitely diesel as I tuck off exhaust at turbo and it's diesel

Certain injector isnt dribbling rail pressure off thro leaking nozzle ?

That's what I thought so I tuck injecter 6 back out and got it recheckedand the guy said it was fine

Not that this is necessarily relevant but how do you know it’s definitely cylinder 6?

Yeah because I took manifold and inside head on cylinder 6 was wet where It pushed out diesel

Now Then..
Is this a Standard tractor or a Premium?? Does it start OK when cold?? Does it run OK??

 

[Diggerdave]

can you swap injector 6 with another cylinder and see if the fault moves?

Check your other 5 injector s . It is possible it's more than one that is faulty... Ps your lucky you haven't got a missing cylinder as fluid on top of piston will wreck it.. Which it will if you can't find where diesel is coming from & get sorted.

It's after getting all injecter,s done The injector it's giving trouble on got a new nozzle I thought about swapping them to see if problem moves

As above your lucky no wrecked piston, I had it where injector on number 1 was leaking , bits of piston melted , smashed the valves , head , bits sucked through turbo etc. The result is it cost us 8.5k to rebuild it. Get it fixed , just go to JD stealer as your first loss will be your cheapest.That is to get it fixed.

The amount of work there is involved with changing these injectors, I would use genuine JD Reman injectors.. They have 12 months warranty..
Have you replaced the copper washers on the bottom of injector bore and used the correct installation procedure??

I have a source for genuine brand new Denso's at hugely less £££ than the dealer, cant trust the reman ones ime.

As for installation, I was thinking about if spill could somehow leak into the cylinders when it's shut off, but he'd have lots of chuffing when running from combustion gasses or it inflating the diesel tank from same if the injector seat was cracked etc ???
