Posted: Wed Feb 23, 2022 0:59 Post subject: When is it time to replace injectors |
|
|
Hi I have a 150 - 2012 and it has 106K miles, It drives fine but anyone have thoughts on when you should change the injectors? I watch a youtube channel called Fourby4Diesel and he seems to think injectors should be replaced before the mileage I have reached. Any thoughts ?
Also anyone recommend where I would be genuine Toyota injectors ?
Thanks
Andrew |

Have you checked any of the injector stats with techstream?
The same guy has videos on what to look for.
I dont think the 150 is the same as the 120 in terns of leaking injector seats, but the injectors themselves probably still wear out eventually. |

I don’t think you’d need to do any injector predetermined replacement activity, I guess you could apply that wear/tear logic to the majority of the components of the car, but if you start thinking like that you’ll never sleep,at night 😀
They’re not cheap, I’d just wait for them to fail, if they ever do.
I had a 120 (in fact I think I was the 1st to ever post in the 120 forum section about the injector seal failure)
And when moving to the 150, the injectors were in the back of my mind (after getting a £5k bill for an engine replacement, but Toyota did go 1/2’s on it, even with a tuning chip in place😁)
But no problems as yet on my 10yr owned 2011 150 LC, Toyota were aware of the 120 injector issue, so I’m sure they will have would sorted it out for the 150 build series, I.e. qty 4 coppers washers I’m sure won’t have broken the 150 build budget cost base for,Toyota 😀
My tuppence worth. |

I had a 120 that had done 180k and still on the original injectors. _________________ Do more with less. |

I’ve got a 2010 LC5 with 106k (FMDSH). Drove like a charm until about 12 months ago. Started kicking out black smoke (still does), and lost some power. Put in for a service overseas at a BMW garage to investigate black smoke and they found all 4 injectors had failed on some of the tolerances. Cost me about 2000 euros including fitting for remanufactured bosch injectors. Returned to UK. Car had deep engine clean at a japanese car specialist to remove carbon from exhaust manifold and i had a standard ecu remapping done too. This got the car through its MOT and the engine performance is now spot on. Still kicking out some black smoke under hard acceleration. Not sure if I’d fork out 1.5-2k for no reason but just keep an eye out for any other engine issues or warning signs. |

Not sure what is meant by deep engine clean, or how they did it, but cleaning carbon from exhaust manifold, is only a small part played.
The egr in particular, and the throttle body can get choked with build up of sticky, tarry, black gunk, that needs to be carefully removed by hand in conjunction with for instance, paraffin, petrol, diesel etc in a parts washer.
This *beep* affects efficiency/performance
No amount of branded cleaners poured in the fuel tank will efficiently clean these areas, they need to be dismantled.
Beware of products that 'up' the cetane rating of diesel to supposedly burn off this *beep*, the idea is, to make the engine run hotter to burn it off, and can be detrimental to the engine.
BTW, the original copper washers used by Toyota, were not up to the job, and were replaced by thenselves/with injectors as a recall by Toyota years ago. There may be some vehicles that slipped through the net, as it was between certain years.
Since then they use/supply an aluminuised version of injector washer, not copper which some injector supply specialists still include. |
