Yeah Toyota said it should be rebuilt every 200k miles or so at least twice. With a 2UZ it seems like basic maintenance is all that's required to make it to that 600k mile mark. Around 200k the 1FZ will at the very least start leaking fro the valve stem seals.Now 2 x 2UZs + A750 with 1,000, 000 miles (1.6M kms). Having had both, 2UZ for me...

I remember when the FZJ80 was released with the mighty 4.5 litre inline 6, Toyota's ads pointed to it being able to be bored 30 thou' up to 3 times.
Oh and fuel consumption?
I wanna Australian 1FZs were more reliable due to the lack of EGR etc., especially the later coilpack ones we never got.Funny how different countries have different views on the same things. Here in Oz I reckon a knowledgeable jury would side with the 1FZ over the 2UZ for reliability and longevity.
IMO, while the V8 rumble is great, and no doubt the 2UZ with A750 is much nicer to drive, I'd feel much more comfortable driving an FZJ80 with manual transmission into a war zone than I would a 100 series V8 Auto
How common are these electrical failures on the 100s though? And the FZJ80 isn't immune to electrical issues either. If you really wanna avoid that you'd have to get an old 1HZ-powered Cruiser or something with mechanical injection.Remember he didn't ask about "better", he asked about durable and reliable. Better is highly subjective, subject to individual opinion. It's possible that 2UZ is more durable, that is long lived, but it's a close call. The 1FZs are awfully stout and the later ones seem to be less prone to head gasket problems. They are both so long lived that it may be too soon to be asking the question. Let's wait a couple more decades.
But on the subject of reliability I don't think the 1FZ can be beat. Modern electronics cause too many sudden inexplicable no-run failures, often resulting in a tow. 1FZs limp so well. Engine reliability has to be considered in the context of the electronics that make them go down the road. If your ECU fails or your VSC system is braking on one side of the vehicle and running you off the road there's little consolation in knowing that your head gasket is solid. Your modern engine is a co-conspirator in the problem. Modern electronics are not without compromise and are generally shortening the useful and economic life of automobiles.
