Injectors R/S at 102000ks?

Postby Bammo on Tue Oct 10, 2017 9:36 pm

2010 MN Triton @102,000 ks started making a bit more of a clattering noise over the past year or so. Hard to pinpoint when it started. A few weeks ago started surging a bit, especially in the morning for the first 2kms then settled down. Mechanic is currently doing the timing belt as part of the 100,000K service and popped the camera inside the manifold. He reckons its as black as sin in there but no different to normal.

What is different are the injectors. Bear with me here as I don't know much about them but he says the readings from them were really bad - large variation and he reckons they read like 200,000km injectors not 100K. He reckons this is the cause of the clattering noise and cold starts usually exacerbate the problem.

So, is this likely to be covered under warranty? ( I have the original 10year powertrain warranty still active). Mechanic mentioned this is likely to be a $2500 - $3000 job to replace them.

Any thoughts? How hard to push the warranty angle on this?

If your mechanic ahs the gear then get him to do an SQL. This should even things up a bit. Alternately get a dealer to do it (making sure that your service history is 100% up to date) and, if they were to 'discover' a problem they might even offer to fix under warranty.

Don't think so, but worth a try.

If work is so terrific, why do they have to pay us to do it?

So I spoke to the dealer today and he said the powertrain warranty only covers the components inside the engine and that injectors are specifically not covered as they "aren't a main component of the engine".

:shock:

So I have been searching online and its bloody hard to find a definitive answer to this question - I cannot find anywhere that states the injectors are not covered - does anyone know for sure?

Unfortunately that's correct, Bammo. They treat injectors as consumables, same as brake pads.

These injectors only have a life cycle of about 200k kms at best. This will depend a lot on the quality/cleanliness of fuel over that period. I think it's absolutely crap that the manufacturers cannot provide better filtration system for this reason. 100k km out of these injectors is not what I'd call good or fit for the purpose imo.. but it only takes one tank of crap fuel to destroy an injector. Anyway you could try pushing consumer law at them and coming to some arrangement? Offer to pay the labour if Mitsubishi cover the costs of the injectors? You could get other work done at the same time like timing belts and valve clearances?

As with most of the high pressure diesels these days it doesn't really seem to matter what brand car manufacturer it is, they all die o lot shorter than the old mechanical injectors. It wouldn't be such an issue if they didn't cost you a kidney donation to pay for the damn things. Even genuine Denso ones NOT from a stealer cost enough. $1,600 for my prado (dealers want $2,500) and that's only the injectors. Doesn't cover cost of pipes, seals, etc and of course labour costs if you can't do it yourself.

If they only cost a couple of hundred each i could live with that with a shorter lifespan but the prices are ridiculous for the lifespan of them. Just pity those with V8 diesels and the bill for replacing 8 x of them and not 4.

i would be more suspect on the suction control valve rather than injectors,

I wonder how many parts get changed unecessarially by misdiagnosis?

The ole 3.2 sometimes sounds a bit off so a dose of 2stroke and it literally changes character. :)
Don't let the b'strds get you down!!
