Just bad luck really, got to see the positive side, it will have new everything and run great ready for another 400,000klm.
Istrument cluster could have had issues and been replaced with one from a wreckers, which happened to have lower kms on it, as many would, nothing illegal about that, just a possibility.
Maxx, What is the difference between illegal and highly illegal?
I'm hoping for a good run and I plan to run it for a couple more years. This truck had a fully logged service history with our local Toyota dealership, and I knew the seller through work, so everything checked out and nothing dodgy was going on there. Also the general condition of the truck (mint) was a good indicator that the kms were accurate.
Basically the seats and seals failed on the injectors and that caused the leakge which damaged the pistons. The injectors them selves were fine. It only takes one dose of sh*tty fuel to damage the seats and seals apparently.
After talking with a Toyota technician yesterday he said that they (the mechanics) only became aware of the seats and seals servicing around 12 months ago when it was released by the big wigs. Apparently Toyota NZ knew this for sometime before making it a recommended servicing procedure. Unfortunately this was a month or so after my 150,000km major service, so that is why I wasn't made aware of it.
Anyways, they recommend doing it every 45,000kms and I'm not sure of costs but can find that out easily enough. The engines they are performing this service on are not having any of the 'injector' issues following servicing, and no engines have failed since following this procedure, and the mechanics are confident this is the foundation of the D4D issues.
Its not a difficult process, you just need the knowledge of the high pressure injection systems to ensure you carry out the job safely.
The oil pick up screen is also another important component to keep an eye on as they tend to block up over time and obviously cause engine failure through starvation. Its not too uncommon either.
