Hi there! Thank you for the excellent explaination! It seems I have G144, so not with LSD?

Hello all, I would like to know if the 1990 LJ70 with round head lights (2-LT engine) has standard a LSD differential on the rear. I've got a hunch that my LSD doensn't work properly anymore or maybe I even don't have one. Is there also a way to modify the differential so I can "easily" lock...

Hello Shayne (and the rest of you) To close this thread I eventually (a half year ago) found the problem... It was the valve of the waste gate that didn’t closed completely. When I dismounted the bracket that holds the valve rod (and by this action it closed the waste gate valve) I heard the...

Guys, I found this on the internet: http://www.stonefisk.com/doc-arc/def_man/ThermoGuard_Tdi_Tuning_Rev.2.pdf It is a manual how to adjust the boost compensator to get more out of your engine. It is not the same boost compensator as on the landcruiser but the principle is the same. I think it is...

I just found something that may explain my problem. Apparently you can rotate the boost compensator diaphragm to adjust the shaft which is some kind of tapered. There is a great youtube video explaining this. So it is possible that the shaft is now at a setting that doen't do much! Verzonden...

Yeah, I might want to check the injection pressure.

I disconnected the boost compensator and I had no difference in performance. How is that possible? Checked the injection timing and is correct. I already put some injector cleaner in the tank.

Nope [emoji4]

The power is better at higher rpm, but I think that is because the turbo kicks in. But a friend of me has almost the same cruiser (lx version with electronic 4x4 and power steering) and the power curve is the same but higher (about half!) on the whole line. I hope I am a bit clear :-). The...

Yes there is a vacuum pipe from inlet to a vacuum switching valve, which then splits to the pressure sensor and boost compensator. But somehow I doubt it isn't the boost compensator, because the lack of power is mainly in the lower rpm. Or does the boost compensator changes the fuel mixture when...

I did not replaced the boost compensator, I only checked if the diaphragm was cracked and I changed the settings. Sorry English is not my native language, I did not mean replaced the boost compensator but only changed the settings :-). I will post an update on saturday evening if I solved the...

Hi Shayne and Ben, and thank you for the effort. I already changed the position of the full load screw, with some black smoke at full throttle as result. However, the power stays the same. On top of the pump you can see the boost compensator, the bolt on top has no use and is a bit loose (thread...

I looked into the 2LT manuel and found the following cause of lack of power: Does anyone know where those 2 screws are located? The previous owner overhauled the cruiser almost completely, so maybe he interchanged the 2 screws. Google does not give me any more info...

I found out that there was some "sludge" in the old diesel filter, and also water in the water separator (bottom of fuel filter mount). But I never checked the fuel lines or tank because the new diesel filter still looked clean after 500km. Is there another filter beside the one near the engine...

I checked the vacuum lines, should be fine. Around 3500-4000 rpm the stock boost indicator led goes red, green around 1800 rpm. So there is no leak in the intake I guess and also indicates the boost pressure is sufficient, right? I checked the boost diaphragm and it is not torn.

Hello guys. It's been a while now :) I checked the boost compensator and changed it, without succes. Someone else an idea? Maybe some dirty fuel lines? Valve clearance? Injection timing? Engine starts perfect, no smoke, no excessive mpg,... I'm out of options

Hi Shayne! I took a look and it seems very interesting! This could be my problem :)

Yes it is. No Toyota because a new Toyota turbo was too expensive. But the power loss was already before I repaired the turbo. I will check the compression rate this weekend. Is there a possibility that the valve clearance gets too big after a while? I think it is the opposite way but just to...

Btw, does my type LJ70 have already an ECU I can read out?

Hi all! I have bought an 1990 LJ70 with the 2LT-TD engine (340.000km) last year and since then I changed the following: - air filter - fuel filter - revised turbo with a turbo cartridge/CHRA In the beginning the car stalled a lot and had very little power/torque. So I changed the fuel filter...

On my LJ70 turbo (also CT20 obviously) there is a second threaded hole, I think it is to mount another pipe. So you should be able to connect a boost gauche directly on the turbo. Interesting topic, I also look to boost up mine as it has not much power compared to my other LJ70. Top speed is the...

Thanks! Do you have an idea how much such mechanical locker cost?

Alraight, thanks! I am thinking about weld the back differential so I have a permanent lock. Or sound this as a bad idea?

Yes I already knew that, I mostly let the front hubs locked, I only use the car for offroad. I only engage 4x4 when I see I could use it :) Here in Belgium we don't have much testing ground, so testing the water level will wait (also for the snorkle).

Thanks for your reply Julian! I do have manual locking hubs in front. When I put the gearbox in 4x4 and unlock the front hubs there is no play on the front shaft. When I put the gearbox in 2x4 and lock the front hubs there is play on the front shaft. Both cases with wheels on the ground. 1/4th...

Thanks a lot! anyone could answer my other question?

Hello everyone!! I was inspecting the front and back differential (front one has almost 1/4 turn of allowance when I turn on the axle :icon-redface:). Anyone know what parts are so worn out?? I can still use the 2/4 without problem I guess? But my main question is this: I found a weird part...

I think so too, the jeep stood outside for 3 years with the same fuel so... This weekend I will inspect the fuel tank. Thanks

Thanks for the link, I didn't knew it was that easy :D So I checked and replaced the fuel filter (a lot of water and algae) and the problem was solved...until yesterday.

Another thing: If I check the fuel lines, fuel pump and filter, do I need to remove the air from the system (de-aerate) afterwards and if so, how?

Hi all and thanks for the replies! I ordered a new fuel filter, because I saw this information on a site: I do have a strong unburned diesel smell (even in the cabine) and when he sputters and I "put the pedal to the metal" I see white/grey smoke coming out. There is a small leak of water...

'morning folks I have a problem with my 1988 land cruiser which I can't seem to solve... It starts like it's new, idles perfectly, drives fine but when I let the engine work hard like offroad or a lot of turns it stalls. No power above 1500-2000 rpm at the beginning, if I continue the engine...

Thats the one!!! Thank you very much! :romance-heartbeati:

Someone? :icon-neutral:

Yes I already contacted that company, that is a turbo with number 17201-54060, mine is 17201-54030. The turbo looks also different... :icon-confused: I ordered the same turbo cartridge as on that site with correct number, but still different. Anyone know where I can order the correct parts?

Hi guys I have 2 problems with my 1988 LJ70 (round head lights type) turbo number. On the turbo there is a number that says 17201-54030 TUR32483. I ordered a turbo cardridge to repair the turbo with the same number on it but it wouldn't fit at all... I also don't find another turbo cartridge...
