fuel injection

[jimr1]

I was wondering if anyone could tell me what sort of life expectancy I can get from TD5 fuel injectors .

Never seen a worn out set yet, Jim. Some are still up around the 380K+ mark and going fine. They have the odd failure, both mechanically and electrically, and they can be ruined through water/ contaminated fuel and excess heat like any other diesel injector. But like the Td5 engine, we haven't seen a worn out one yet.

Never wear out ? - Obviously does'nt apply to the td5 heads

Not so, the heads aren't the problem, just the plastic dowels. As regards the odd cracked through the fuel gallery one, well yes they have happened for sure.

But as a whole, they are a fantastic engine.

I understood that the design life was about 800 000 km

hi,justinc ,and djam1, thanks for your anwers. the reason i asked,my son had to have his changed on his nissan navara after only about 1 year old with low ks,under warranty. then heard that some of the toyota v8s are having problems at around 150 thousand ks, so what you'v told me is great news . so one again thanks jimr1

The cruiser injector failures/ lifespan is well documented, even the old 2H really needed tips replacing and overhauls at the 150K mark. With the 1HZ and 1HDT, new injectors are the best bet as they are hard to overhaul properly.

Also, RE the Navara I have heard this isn't unusual....
