100 series landcruiser injector feed pipes

i don't know a single toyota dealer that has ever changed these pipes as part of the service, i am aware of it in the service book but it never gets done.

Yep

Careful with not doing what the book says. You are endangering any warranty that you have.

Hi,
My manual lists the injector pipes as a 150 k interval. The injector lines were replaced in my 2001 100 Series at the 150 K service (for the previous owner) by John Cole Toyota in Atherton in FNQ.

They still had parts stickers on when I bought the vehicle and I discussed the wisdom or otherwise of having it done with the Service Department at the time. They were understandably coy about passing judgement on the necessity and really only said "it's in the manual and if it is to be maintained as per the manufacturers recommendation it should be done".

Now as to the actual need to have it done I have no idea :) but mine were and I'm OK with that.

Perhaps have a talk to an independent Diesel injection specialist and see what their opinion is.

Cheers

They don't need replacing typically. I had my injectors replaced and they were able to re-use my injector lines. A reputable Toyota dealer would have no problem with this.

Didnt do mine at 150,000 BUT DO THE TIMING BELT.

Toyota said they dont do very many so dont worry.

If it aint broke dont fix it.

I think it a preventitive thing for vibration damage and as mine spent 99.9% of time on tarseal it wouldnt have been subjected to wear like an off road travelled vehicle

when mine came up I was a little suprized being a marine engineer. I have never seen a scheculed injector line change before.
Anyway local Toyota mob said Toyota no longer recommend they be done at 150K.

On top of that you are more likely to get a leak changing them than leaving them and as they go inside the tappet cover a leak from the apprentice with the hangover would cause catastrophic fuel dilution.

They wont go brittle, steel doesnt work harden like copper and stainless steel.
Chafing and cracking from loose or over tight clamping is usually the cause of failure.

Replace your timing belt tensioner though, its the expensive bit. New belt is a hour job-easy as it doesnt go round the crankshaft, different to the 2L and 3L.
