1hz

Note: This is applicable to 80-series rigs as well, depending on the market. Since Toyota has been making this motor since, well - basically **forever** (in vehicle years), I was wondering if there are certain years or production runs in certain factories which are notoriously good or bad...

I have 1994 HZJ80 which seems to have occasional issue of the pump keeps clicking off at the pump like its already full at the fuel station. This vehicle have a single main tank only with 95L capacity. Recently, it has gotten much worse and it has been clicking off like 10-15 times no matter...

I've got a 92 HZJ73 with the 1HZ ---- I've noticed some rattle / buzzing noise when I reach around 1.9-2k rpms and higher. Best I can tell it seems to be coming from near the engine. It happens whether I'm driving or sitting in neutral and rev the engine. Its much easier to hear in the low...

I don't have much experience with diesel engines. So whenever I am driving my car in 5th gear and I look at the rpm or hear the engine noise I feel like the transmission is in 4th gear but when I check the gear shifter it's in 5th. Engine revs always fools me to think that maybe it's still in...

I will be firing up my 1HZ powered LC after a little over two years of sitting in the garage. What fuse or fuel line I need to disconnect to preventing it from starting the engine? I want the engine oil to circulate inside the engine before it starts. Thanks!

Has anyone modified 1hz altitude compensator to boost compensator. For example changing the ramp on the pin. Have tried searching with no results but maybe search description is wrong . Found YouTube video by power curve but conveniently left out the most important part ie the ramp mod on the pin.

Hello, Beware I am not an expert on diesel systems or injector pumps and I have no clue what I’m doing half the time, so any advice no matter how simple you think it is could possibly be of help!! Symptoms: running 1HZ under load, losing power, engine stalls, hard to start and sputters when...

Hi all! After working over both of the 2H engines that came with my HJ47 Ute it seems both are low on compression and needing rebuilds. Luckily I've obtained a complete HZJ75 troopy as a doner car with a 1HZ turbo and going to attempt s conversion but have a load of questions before removing...

Hi. I wanted to ask/confirm something prior to turboing my 1HZ. There are alot of post regarding the max EGT's for 1Hz runnign a turbo. I want to know if the EGT;s i'm getting with a turbo will change immediately after fitting a turbo or only after adding fuel. I would assume that whatever i'm...

Seems like there's not much discussion on 1HZ power steering lines. Mine are leaking and causing other problems, and Amayama reported NLA from supplier. Anyone have a part number replacement for 44410-60280? Alternatives? Didn't think this would be an issue to find.

Hey all, What aftermarket brands have you used for these with good longevity? OEM Toyota are insane expensive! Im in the US and they aren't available anywhere so I need to order online. Thanks!

I'm seriously considering fitting an oil centrifuge to the 1HZ engine in my 80 series: https://www.scintex.com.au/products/oil-centrifuge This is something Toyota themselves had standard on the Landcruiser in times gone by, on some years of the 2H engine...

I have read several threads and understand the process but I’m looking for honest opinions on how difficult it is to add a boost compensator to my 1HZ IP? -Tools you wish you had or would help complete it. -Parts that made you run to the auto parts store because you didn’t have it...

Hello everyone My 1hz does not start or starts weak when it is hot.But it starts rapidly when it is cold. Fuel system (timing), the battery or what?

Hi guys! I'm just wondering what RPM are you getting when at highway speed like 120 kmh? My 73 with 285/75 tires is almost at 3K RPM. From there it feels like the engine likes to be on that range. I can pull and keep up with traffic easily and its happy to go 140 kmh/3300 rpm. When I got...

Good evening all I’m completely stumped here. On my HZJ76, which I’ve had basically since “new” (full story here: Ali, the 2008 HZJ76 - https://forum.ih8mud.com/threads/ali-the-2008-hzj76.1272844/), quite suddenly I’m experiencing severe smoking and hesitation. The engine has 16,000km on the...
