1hz

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...

ie. can any 1hz be swapped for any other 1hz? Are there any design differences on the later 1hz's (such as the ones Toyota still makes for 79's in some markets) compared to really early ones like the 1hz in my 80 from the factory in march 1992?

The service information label under my hood is pretty faded and I am having trouble finding legible examples online for a possible reproduction. I am wondering if anyone has a better example under their hood (by the latch) that they can share. Anything would be appreciated, especially an...

Has anyone ever redrilled a 1HZ (275mm) flywheel to accept a 300mm clutch cover? Why would I bother? Because the 275mm flywheels are sorta worthless… and the 300mm flywheels are $700-800.

I used to ask myself the same question 7 or so years ago when the vehicle was at 600 k km's and never could really resolve the issue in my head. According to the people at Berrima Diesel, if the motor does not have any blow-by it's ok to turbo it, but I'm a little hesitant due to the high life...

Just yesterday driving into work.... 700 k km's in 31 years of life since the vehicle was made by Toyota. The t-belt warning light came on as expected to remind me it needs to be done. Is there a contact on the left most number wheel of the odometer that activates the light? I'm aware of the...

Hey, my 105 1hz makes a burr noise when engage to 4H. working fine in 2H. The burr sound is audible in 3rd gear if i drive faster the sound goes away. what does this sound mean? i changed the oils 5months ago,

Serious question time... My 80 is about 350 km off clocking 700 k km's still with original 1hz motor from factory. I know it will need the valve shims done plus the usually 100 k km stuff of replacement t-belt, tensioner, water pump and t-stat to make it viable for the next 100 k km's of life...

Hi all, I just collected Mister Blue, a 2003 105, to daily for a week or two before it goes back in. I parked the truck right after inspection and registration for fear of a timing belt failure. This poor old truck has been out in the UAE sun for a long time and all the rubber has gone bad...

Hey, my friend recently did a rebuild on 1hz 105 because of a cracked head and piston, he said it is common for 1hz, my question is what causes this crack and how can i avoid this for my 1hz 105 that ran around 220Lkm

Just a bit of diesel trivia. I've noticed early Toyota diesel valves will say 'HZ', 'KZ' or 'L' on them which usually indicates engine family. But then I've seen pictures where they're mixed in a given engine. For heck of it, I looked up these part numbers. 2LTE exhaust valve 13715-54040...

Hi all 2008 HZJ71 1HZ LHD , someone know the tie rod lenght ? should be approximately 1184,00 or 1203,00 mm ? thank you Giacomo
