Thread: Toyota announced big Landcruiser spec change & price drops in USA

The mileage you are talking for Nth Queensland isn't that far ahead of some of the commercial boys locally, 4 year old truck with 350,000 on it and a couple of 24months with almost 200. Some of the HT rigs are running over a million in 6 years locally, so we do see those mileage figures here. 10 years isn't that long in the world of engines though, just as a point of call. The TD42 is a 70's tech engine, now that is proven. I can't think of an application it hasn't been used in - maybe aviation (but then I've seen a ground unit running off one...). The P5AT is now close to 35 years old in the basic design, much tarted up same as the Toyota unit but still there's not a lot ground breaking in it. People class that as a borderline engine prone to mechanical issues, but it's the emissions control gear on it that's creating most of the issues that are giving the engine a rep. Vane type oil pump saving 0.75Kw, DPF, EGR, CCV - sort those and 90%+ failures gone. The main issue that the toyota engine has is due to the same reason as the P5AT - "upgrades" due to emissions control gear and making the thing light to save rotational inertia.

Interestingly, it's the same basic design as the Yanmar 4LV marine engine - have a look at the numbers of those in service. That says something referring back to my earlier comment about marine engine loadings. Bit hard to walk home in that application.

Cummins 6BTA 5.9L 250Hp at 2800 rpm detuned marine, good for 10 or 12,000hrs if you look after them. 2.8L 250Hp at 2800rpm - I know what I'd rather have especially with some of our local conditions. Match the tool to the job though, and it will do the job.
