Thread: Does my td5 need new injectors? Or can I service them?

Uhmm...neither?
Clean them with some clean rag and stick 'em back in...

It's not like they are Toyota 'tough' which translates into replacing them every 125k.

They look damn good for 350k. Mine looked like that at 180k. They can be cleaned up a bit. Is there any other indication that they may need replacing? I would just replace copper washers and O Rings and see how it runs. Theres not much on these that can be serviced.

If the motor was running fine don't touch.
New O rings and copper washers that's it. They will likely outlast the motor.
Make sure the seat in the head for the copper washer is clean.

They were very dirty as you can see, im wodering if I can get them cleaned up/serviced or theyre basically done in. The car has done about 350k.

Thanks,

Others have said just to "wipe them down and put back in" seriously diesel mechanical injectors are a precision mechanical device, Injectors are calibrated to ensure that they have the correct cracking pressure, leak back pressure/time, spray pattern, and indications of nozzle dribble.
Personally after being a diesel mechanic for 35 years...I would suggest getting them serviced.

Yeah, that's great. Except the td5 isn't a mechanical injection diesel.
Others have taken the EUIs to injector specialists who have said 'we can wipe them off and charge you for them'

In order to bring at least some substance to my argument...

The EUIs can be serviced and repaired, according to this post by OffTrack, who would know.

Suggest it's not really worth it.
IF you have any reason to believe your injectors are damaged or faulty, sure, send them to either of those companies.
However if you're just doing it as a 'while I'm there' thing, don't bother. Being electronic, they don't have mechanical parts to be adjusted in the sense of a mechanical injector.

Hmmm,

Thanks for all your replies guys, I ended up cleaning them up and changing the seals and washers before whacking them back in.
Id been experiencing a lack of power and seems to have remedied it at least somewhat. I was comtemplating doing the head gasket later this year as some preventative medicine for the old girl, as she has been well and truly flogged. And was going to have the injectors done at the same time.
