You sure? The 2.5 needs valve clearances checked every 30,000km. To do this the fuel rail has to come off. Every six times the pipes have to be replaced. Adds $400 to 700 to that service. Like to see a home mech do that. And don't get me started on removing the carbon build up every 60,000km, timing belt every 100,000km, SCV valves failing, turbo's lasting 90,000km ($3500), injectors at 170,000km ($3,000).............. love that car- NOT!
Sorry. My query was referring more to Nick 08's 3.2L 4m41 powered ML Triton. I aren't really into low tech, cubic inches, but still draw the line at 2.5L high boost Triton, Navara, Amarock etc type donks regardless of the servicing issues. Didn't realise there were so many issues with the MN 2.5L.
Not wanting to question the work you had done on your car but I do have a few queries (the mechanic in me querying less than professional dealers
)
Are you suggesting the fuel rails have to be replaced every 6th time the valves are done ie 30000km x 6 = 180000km? I have never worked on a modern CRD but from what I have seen I thought they just ran separate injection pipes from an external fuel rail (typically mounted beside the block, above the fuel pump) to each individual injector, the pipe being connected to the injector outside the rocker cover.
Timing belt at 100000km. Thats basically a given for any Jap belt driven cam. I thought the Toyota 6s were also belt driven. What are their belt replacement intervals?
Carbon build up seems to be an issue for any EGR diesel doing a lot of city work.
Turbos lasting 90000km. Ouch. How did they justify that not being a warranty job?
Injectors $3000. Seems cheap. I thought Toyota ones cost that much each. At least mechanical injectors can be rebuilt, but if you had to replace them they would probably cost at least that.
Ah huh just found this on the Triton forum -
I must stress to all and in particular those who don't use mitsi service. $150 of the cost was replacement of 2 injector pipes. These need to be removed for tappet adjustment. Apparantly they can only be reused 4 times but must also be inspected for pitting prior to refitting. Mine were pitted as shown to me by the dealer. These pipe fittings compress in their tapered fittings and must be torqued correctly with a specific tool which a lot of independants are unlikely to have.
Due to high pressure diesel these can leak if not maintained, the leak ends up in the motor and the result, catastrophic engine failure. If this occurs and the items have not been maintained or replaced at max usage MMAL will not cover for warranty.
This means expensive................
Just like an old fashioned mechanical injected truck motor (but lower injector pressure so less susceptible to wear).
Reminds me of an old 50t dump truck I serviced on a demo site once. Old GM 8V71 engine. Dropped 50 litres of "oil" out. Only had to put 20 litres back in. I said to customer "I think there is something seriously wrong with the injection system". "Na. She'll be right."
And just like a good old fashioned lump of Yanky iron, it just kept going.......
