so after doing yet more research into the 2L-T engine it seems that some of the earlier models 85-57 had head gasket problems (bad oil leakage). the ones since 1988 were to be much better.
it also seems from what i can tell that the head crackign problems is directly associated with driver abuse, i.e. over heating.

so here is what Luxury is going to do to combat this concern. we will be drafting up a pamphlet for driving tips and installing a pyrometer into all Hilux and LJ71 and LJ78 model trucks we bring in. any trucks that are 1987 and older we will replace the head gasket prior to selling the unit (very simular to changing out the BEB on the HDJ engines) to prevent the problem before it occurs.

i hope this will alleviate any concerns about these fuel efficient engines.

cheers

Good idea Wayne.

Myself being a owner of a LJ78 w/ lift and 33s and with over 200,000k on the OD, I know they "can" be good engines with a little guidance on how to drive them and what not to expect from them.

I have a bit of set guidelines to anyone who drives my LJ78. I think it is funny to have to set guidelines for the drivers but I also feel that busted 2L-T/II/TEs are from drivers expecting the 2L-T/II/TEs to be something they are not......FAST. They get the idea that it is a turbo as labeled on the door that they can hammer on them. Plus these engines are damn moody to outside temp, atmosphere, and humidity.

My terms for driving my LJ78:

1) Don't try to make it go fast. It is not fast.

2) Don't run it over 3,000 RPM for long periods of time. i.e. highway

Golden Rule: Skinny pedal half way to the floor will get the desired performance without any danger to the engine and keep you in the powerband through all the gears in an auto. Heck, try it sometime. You will be amazed at what that LITTLE engine will do with half pedal.

I could go on but those are the important ones for driving.

The upside to all this guidance? I get over 530 kilometers out of one tank of fuel in my heavy and rather large 78. Should be even better in a 71 or a HiLux.

This is good, Wayne.

Perhaps emphisize that maintenance/full working effiecency of the cooling system with the L series is as important as watching the EGT's.

Has anyone ever tested redlines Water Wetters claims of dropping temps?

Thank you for the info, I have longed for a 2LT powered 1985 mini for years and that was a good bit of info.
 
12h-t

Hi,
Are there any 'guidelines' for operating other models, specifically the 12h-t in the hj61's?
Thanks
 
the 12H-T is bombproof, but after x00,000 kms of lugging in high gears the transmission and T/C can wear prematurely, at least on the manuals that we have here. Use your stick :D

Hello, can this difference be traced in the EPC? Was there a 2L-T in 85, thought they came first in 86? Was not aware that the 88 2L-T was different from earlier years, but in 89 or 90 we got the 2L-TII. I guess it is not this one you mean?

I am curious, since in Norway we only have the 2L, and 2LT driven cruisers from 85 to 88. Then there were no cruisers offered at all untill 96 (which is bad). Knowing that the 88 is somehow better than the others would be useful.
 
Well I thought in all Toy diesel models are the same guidelines to get proper performance and safety.

In my 2H engine I aply the gold rule skynni pedal, half of throtle and you get awsome ( remember is a Land Cruiser ) power .. with econo ..

Yesterday when I come back from the beach with my TLC my top speed was 120 km/h but at 3000 rpm to much as Mr. Pac Toy note.

My engine it was in really good shape, with AC and Flex a Lite S fan, have a good temp inside 22ºC but outside 36ºC with 94% humidity are to much for my engine .. I thought in this moment one turbo was the solution .. but not my case.

If outside you have a fres weather, you can get better performance from your engine. I can put my pyro in 1250 ºF easy .. but is not the idea ...

David,

That is just my guidance to anyone who is going to drive my LJ78. Speed limit here on Okinawa is 80 KPH. So there is no need for them to be running the engine over 3,000 RPM on the highway. You can run 80 KPH @ about 2,600 RPM in my LJ78 with 33s. So there really is no need to push the engine above that. You can set the guidelines for your cruiser anyway you see fit but those are my guidelines if you are going to drive my cruiser.

Regards,

Randy

as far as i am concerned if a weakness is noted in a particular engine it is good to change the guidlelines as such is needed.
all the engines have their weaknesses, i have not found them in the 12HT yet but i am sure Canadian abusive drivers will find them sooner or later.

the first 2LT came into production in oct of 85...
 
Thats why my next rig will be from you Wayne, you should be beating customers off with a stick, the way you do business.

cheers

Oh as for the water wetter, I have an old 1981 Kawasaki LTD 440 Snowmobile, I use water wetter in and it droped the temp 15 degrees or so.

That seems like a good policy. I heard a report that another of the importers takes all his new rigs and after his normal barrage of checks, tuning and maintainance runs them up a particularly long hill in the mountains to see how they perform. If they survive, he sells them and if they break he fixes them and then sells them. He's reportedly 0 for 5 on the 2LTs and claims he is not bringing any more in.

Hey Randy, you have the cruiser up and running now? Didn't know you had a 2LT in it, thought you were going 1KZTE. Need to see some pics :)
O, and I totally agree with you on how to use a 2LT engine. ;)

yep I'm 226% sure that not all engine have the same weakness, but you know your engine.

In my case my Toy is not a common car, o less are not a usual Land Cruiser, not a usual old Land Cruiser. I thought not all persons can drive my TLC, with 37" SO, 10" of lift, gears .. bla bla bla bla bla ..

In all case my engine is the most stock thing that my Toy have .. :D uff don't thing about the brakes .. :cheers:

Eurotrash,

Hey Roger, great name! Yep, it has a 2L-TE in the Prado. My computer got wiped out from the worm virus and I have no pics available. You can see it on Brian's web site though as he has many pics of it there. brian894x4.com

1KZs are the way to go for Prados though. Would like to have one but still a bit spendy to aquire.

Will send a email in a day or two as I planty of other things to discuss with you.

Take Care,

Randy

Crushers, I've had a 2LT in a HiluxSurf and yes the head cracked ('91). Being a member of a good UK surf forum Ive not read that the 2LT head changed at all in the early years but I wont dispute you saying they did. What is true is that Toyota changed the design of the head insofar as the water channels were moved further away from the bores.

The man with the most knowledge on this from that forum is Stevo and he lives in he UK, I dont know him but he knows busted surfs. He is highly recommended on the www.hiluxsurf.co.uk forum for repairing 2LT surfs. Heres a bit of a link http://www.yotasurf.co.uk/members_pages/stevo/index.html
 
in 1987 there was a change up number so i assumed my information was correct.
i am sure the newer head could be cracked as well if overheated...

do you know what caused yours to crack? have you owned your from new?
i will do some reading on the link you posted. thank yo for th elink

cheers
