As i am a landcruiser fan, for the desiels, would have to say the 1HZ. Ball-loads of torque and never say die, go even better with a turbo. What does everyone else think?

Ive had a few 2F's and 1HZ's but id love the first multivalve diesel that came out in the 80 series, or a close second would be a 12H-t, both sound great go for ever and give u a fat a cat could not scratch LOL

12ht !!!! would have put one in my ute but could not afford at that time so i settled for the trusty 2h then turboed it 2 years later!!!!

3B or 13BT for the diesel.

For petrol I would say the 2F, and the 3B or 13BT for the diesel.

Andy
2f and 2h for life expectancy, reliable simple pushrod single valve engines who can argue with 350,000km plus on a 2f and 450 plus on the 2h......... and then the 12ht, in theory it is basicly a factoryu turboed 2h but its such a better combination than the 2h with a a/market turbo.

Well this topic should be interesting...

Well my Cruisers have had 1HD-T, 1HZ and 1HD-FT engines, the 1HD-FT comes first and the 1HZ very last!

The 12HT is also a favorite, hard to consider it's related to the 2H at all.

all the 2L, 3L and 5L diesel motors are about as reliable as they come

I haven't owned any of the petrol engine Toyotas, but I like what I hear about the v8 Lexus engine. Out of the diesels I like the 12H-t for the best ever turbo diesel engine (especially for reliability), and I like the multivalve turbo diesel in the later 80 series because it would still be quite reliable, but with more grunt.

I know that the modern high pressure diesels are very impressive, but I would be concerned about reliability once they become cheap enough for me to afford.

I'm not up with the most recent Engine codes (ie new V8 Turbo Diesel) but has anyone even mentioned it? Is it even worth mentioning around greats such as the 12HT or must it first stand the test of time?

Just my deep & meaningful on toyota engines....

From what i hear it is a good motor, but i believe it will have to stand a test of time before i believe in it. I liked the 1HZ cause it lasted for years without any major problems. Hopefully this V8 will be the next 1HZ.

It would definately have to be a tie between the current Prado D4D engine and the new 70 series V8 turbo diesel, thou that will be overtaken by the 630nm Twin turbo intercooled 200 series engine......which as impressive as that is will still be very under-powered to retain good 'ol toyota reliability.

If any of you have a chance to take any of the new diesels for a drive, you will be mighty impressed. yeah, the old diesels were good for their time and may be easy for the backyard mechanic to work on, but for performance and efficiency you cant come close to the new engines.

It's called a 1VD-FTV, impressive to drive and listen to, but yes it's still got to stand that test of time.

I'm with Andy-b on this one... the 13B-T
ummm no, of course I'm not bias :)

1HD-FT ...... they are quiet, smooth and rev nice. Not to mention that they have heaps of potential in stock form with the standard turbo. (Though they do need a tune if standard :D)
smithie
13-07-2007, 01:02 PM
1HD-FT gets my vote... in stock form its got modest power and great reliability... thats what toyota is all about.. but its also built well enough to allow for some decent performance gains...MMmmmmm...

1HD-FT gets my vote as well. Turbo, multivalve, reliable, good power and no electronic bits.

No mention of the 1HD-FTE?? Been around long enough I think to get a vote both mechanically and electronically. Probably the highest power and torque for size in Jap and US engines, maybe of just about any non-CRD engine (correct me if Im wrong!)

This thread should have been titled "Which is your favourite Landcruiser diesel?"
All of them were good at some time or another.
Toyota's only diesel which is crap is the 2LT which is uncommon here.

My favourite for all round dependability ,power,longevity and economy is the 1HZ;)
I forgot to mention how easy it is to work on when it needs a service:D

I would also chalk the No. 1 position to the 12HT.
Look after them and you could almost bank on 1,000,000km without touching them. Great power too.
Would love one in my 80.

ok so the 12HT seems to be winning the votes atm and since im looking at either upgrading my HJ75 troopy engine or to a HZJ75, can someone who has had both give me some help in this thread: http://www.4wdmonthly.com.au/forum/f44/2h-hj75-1hz-anyone-done-36094/
I have a 2H and its not enough and about to die i think.

80 series.
It's the multivalve turbo.

I have the 12-ht in my 60, and I think it's a pearler. For an engine that is exactly the same size as the 2h (identical bore and stroke), it is leaps and bounds ahead. And real easy on fuel too.

I know the 12H-T is not as new and powerful as the current toyota offerings but this old motor has stood the test of time for reliability! For a engine design upwards of twenty years old and still fetching around $6500 second hand it says it all. I'd slot a 12H-T under my 40's bonnet any day of the week!

3b...2h..if looked after no props in seeing the clock tick past 1000000.ive got the 2h had it for 12 years and all i have done is oil and filters.its never stoped..about time i do injectors but have done 200.000kms and never touched a thing
Walt

its amazing how tractor like the old h and 2 h motors and even the 1HZ are too i guess. i had a mate who had a hj45 with an old H motor in it with 35 inch mud terrains, i reckon my massey ferguson had more pick up then this thing, but the torque, it got everwhere any other car did, just alot slower.

yer baby i got ur back, I cant fault my 3L as far as reliabilty comes. Im not sure what went wrong when toyota decided to throw a turbo on the L and produce the 2Lt but I no for a fact and has been proven by topgear that the N/A 2L is a trooper.

First - 12HT
2nd - 1HD-FTE , still reasonably new yet to get full title

Last - 1HZ

12H-T for me,She sounds like a Mack truck at full noise! (drool,drool,drool)
She's got 475k in her bores and charges like the day it was built.

It would have to be the H series and also their cousins the B series which are very similar. Don't forget that diesels aren't about raw power, they are designed for commercial applications where torque, fuel economy and reliability are paramount. But there are better diesels out there not made by Toyota.
But for me I'd say the 2H is a winner. Easy to rebuild as it doesn't have a timing belt and uses push rods. No problems with injector pumps as they are inline and oil lubricated. All you have to do is change the oil and maybe the injector nozzles and adjust the valves every 200,000km.

I'll jump on the 3L bandwagon aswell. Definately not the fastest but reliabilty is A+

I'll also have to put a vote in for the 1HZ. Just spend a fortnight out on a friends cattle station on the QLD/NT Border. They've got 2 cruisers with 1HZ's. These things cop and absolute flogging and doesn't phase them in the slightest. The pull these things have (especially compared to my little hilux :p) is unbelievable.

ive allready voted but your right andy,get out of a troopy with a 1hz back into my hj61 the 1 hz sounds like Andrew denton but the 12ht sounds like Chopper Reid.

OK then, I have couple of hilux's, with a 2L and 3L Oiler (Love the oilers) and the missus has a Lux with the 5L.

Power, NFW. But they pull all day, every day and the fuel consumption is reasonable.

I've done 115K (odo 185, 000) in th 3L without a problem. Had the bearings done at 145,000km as a precaution - based on the 150K horror stories about this motor.

The bearings were white metal and clean as - keep up the service and they'll look after you !!!

2L currently about 270, 000.
5L currently about 175,000.

PETROL, is for cleaning Diesel parts, on the occasion they need a rebuild !!!!!!

POINTS - are the individual reasons you convince a mate to buy a diesel not a petrol.

SPARK PLUGS - are in the lawnmower........somewhere ??????

LEADS - are diesel drivers who check out the river crossings with their trucks, before the petrol heads consider getting their "DONK WET" ;)

I would have to say:
12ht
1hdt
13bt
14bt
All very simple long lasting and reliable engines, and are all direct injection.

I just love the lack of electronics on the olde oilers,you can fix them just about anywhere (should a problem ever arise) using basic tools,not having to worry about the quality of your 12volt signal,bad earths,or water buggering up some little black box that has a thousand wires going in and out of it.Yep, the KISS theory works well for me.
