my old man knew a guy that got his to 900000 without a problem so decided it was time for a bit of forced induction which the truck loved until 1.2 mill when the guy flipped it and wrote it off.

Yes theyre a strong motor but if you don't give them decent oil every 5000km you'll find the valvetrain worn out faster than a hooker's privates. Plus the sooty oil ends up as sludge which slowly blocks it up and returns you with spun bearings.

Another common issue is the cooling systems arent maintained. If its not running at the right temperature it will be very sludgey as the pistons never really expanded to their operating tolerances. Plus if the coolant isnt changed regularly with the right mix you end up with a rusty or scaley cooling system which will also fark a td42 over real quickly.

But in general they will just go, and go and go.
