Toyota 1HZ engine - are they a good engine?

I'm interested in what people consider "a slug".. Will it get upto the speed limit in all states but the NT? or could you not expect to get over 100kmh ?

I can get Darkie up to 120km/h towing the trailer loaded going down hill or on a very long flat section.
Hills of any size are 2nd gear sub 40km/h with trailer and around 3rd gear 60km/h without it.

Cheers Kev

Are they any good ? Surely the 1HZ must have been responsible for much of the advancement of mankind since WW2 - so many of them in use, with ledgendary odometer figures - understressed, plodding away endlessly..... I reckon I've seen them on oil rigs at Moomba.... could be that they used them for Yanmar marine applications too.

Well said/pictured Doug, I have seen them around that mark in both the 4bees and coasters, good motor, change oil and filters like a religion.
Swambo just pointed out that is 146 oil changes ..... $orry. I will now hide the calculator...

Thanks Doug - that speaks for itself! dingo

Lotzi
No.... about 72 changes, I have always done oil at 10,000 intervals and I always add Nulon .

Lotzi
Oh and I forgot to add that in each 10,000 I do not have to add oil , even today.

This response must surely be the ultimate "A picture is worth a thousand words" statement.

Well done Doug.

Gday Doug,
When I first looked at it I thought you were explaining "slug"
( the speedo)
then I realised the odometer!! Hahahahahaha

Shouldnt have owned up to that hey???

LOL

G'day Doug
My last Coaster, I tried a few different things, I ran Amsoil synthetic oil to 10k, with a filter change at 5k, eventually I went back to oil/filter changes at 5k, just felt more comfortable, you know what its like... fresh oil they just purrr, and still not use oil.
If anything with these motors, i would try a spinner type filter similar to that fitted to Scania, run to 20k and do an oil analysis.
That Coaster is now out at Alice doing Town/Rock and Kings Canyon runs and still going strong.
I am just a loyal Toyota person, have been for a long time.

Daughter has a 1HZ in a Troopy, I have still got the old 2H in a Troopy if anyone is concerned about "Sluggish"
Considering I service both vehicles at around 5K each (mine from new in 1986) I reckon they aren't a bad truck doing what they were designed for.
If I want to blow away the "Sluggish" I wheel out my Honda 1100XX and annoy the young blokes at Eastern Creek.

Hi Doug,
What nulon product do you put in (oil addative but which one). Often wonder what they are like. Obviously it has worked for you. We are up to 320,480 km's and would love to see it clock up your km's. I have found it to be a fairly faultless motor. Is yours turbo or standard. We service regulary with good oil etc. Out of interest what oil do you use? Thanks in advance. You MM me if you like.

Thanks
Josh

Thanks

Had one some years ago and sold it with 520,000 on the clock, saw it the other day after some 10 years or so still going. The only way I could get it over about 115Kph was to drive down a mineshaft.
