the TD42 nissan or the 1HZ toyota diesel. trying to decide on which diesel to put in my jeep. the diesels are from the years 1993 to 1997. which engine has better durability and less inherent problems? not trying to open a can of worms--- just trying to get some honest opinions. i realize both diesels have been on the road for many years. cheers, robert

Toss a coin, they're both very reliable engines and you can't go wrong with either although I'd go the TD42 but that could be a bit of bias in that call!!

I'd go for the 1HZ for the following reasons: Quieter,smoother revving, more modern OHC design. Less maintenance requirements, less servicing costs,more abundant secondhand parts,higher torque output and generally use less fuel per km. Durability is about line-ball, cant' seperate them really, so down to running costs, Toyota is far cheaper to operate.

Steve do you have the figures for power and Torque of both engines?
Just interested to know.
Cheers, Mark.

Bit confused why 1HZ has less maintenance requirements. Both require oil changes @ 5000km, both require 10 litres of oil, I can get oil filters for TD42 for $5 each(micros), never seen a 1HZ filter for $10 or less. I also dont have to replace cam belts every 100 000km. Where are the extra maintenance costs? I dont use any more fuel than a mates 1HZ 80 series either. I reckon the TD42 is cheaper to operate but does lack some grunt compared to the 1HZ.

TD42=85kw - 264nm @ 2000rpm,
1HZ= 96kw - 271nm @2000rpm.
Later versions have a slight increase in both power and torque in both engines.

Thanks mate. I wasn't sure of the 1HZ figures and was thinking of the TD42T figures I have for my GU. It is a point to consider to about the timing belt.
Cheers.

Ok Nugget.
TD42 requires 2 filters every time. Average cost of $13 each, thats $26 for starters.If you can get fiters for $5 then please give me the part number quick!
Valves clearances for the TD42 need checking and adjustment every 20,000km and they do need it! Water pump life is questionable, and seem to be a weak link on the engine, although that does depend on over zealous mechanics swinging on tensioning levers! Fuel consumption is such a variable argument, but consistant comparisons with those that go away with me, constantly show an advantage towards the !HZ. If you have to pay somebody to do tappets for you,do not have a"contact" for cheap filters, then you have to be in front with the 1HZ, only just but nevertheless.

Gday
Why choose these motors? There are a host of new diesel 4 cylinder t/d motors coming out like the 3.0 Prado/surf turbo electronic? More power and economy.
Easy to come by at the importers...
Anyway your choice,presuming with the td42 and 1hz you will also fit gearboxes/transfers out of these models aswell, the Nissan gearbox is better than the Toyota as far as shifting goes,(later than 95 Toyota had improved shift) the Toyota has better low range gearing 2.48 vs 2.02.
Remember you will get stuck in the mud with a Toyota :-) only joking guys
