- Today I go through how I check and re-shim my valves on the 1hz 80 series motor.
This is to be used as a guide only and is what works for me. I highly recommend using a mechanic if this is out of your skill set.
Grab a beer watch the video grab the factory service manual and have a go if your keen.
Cheers, Timmy
Thanks. Just did my valve clearances watching the vid.
1HZ
1). 20, 35
2). 20, 40
3). 20, 40
4). 20, 40
5). 20, 40
6). 20, 40
Only had .05 feeler gauges so could NOT fit 25 and 45 respectively in any. Didn't have to change any.
Nice! always good to check
Tim I can't thank you enough mate! (replying to my comment (differrent' account name) would have been cool, but heck, the video on water pump is over a year old and you are a busy Dad and Hubby) I watched your water pump/timing belt video I notice I had a blown rocker cover gasket, and that's why I'm here watching this video as mmmm I thought may as well check valve clearances. The extent of my mechanical ability inlcudes (but is limitless with the right teacher such as yourself) is brake pads, and bleed change rotors, install new PS gear box oil change and installing aux battery hooked up to alternator, CB radio, flood lights etc, never done 'in' engine work before my biggest fear the timing belt! but thanks to you Tim, you given me the confidence to give it a crack! You're a bloody Ausssie what's more. A clown from the USA with a youtube video said you don't have to remove timing belt to get to water pump. Umm did he not know that diesel versions exists and not all Landcruiser 80 series are petrol? Thank cricky I found you Tim,
Thanks again

Thanks for the vids champ. I had a Runaway with my 1HD-T (long story but low light overfill of oil blew the intake seal 🤦♂️).
I have had the CT26 recored, plus ported and polished the exhaust Mani same time, initial borescope didn't show any internal damage + no shrapnel or swarf in oil dump.
Now only running on >3 cylinders (no nasty noises) now so about to do timing belt (60k until next due) and check valves/springs/shims, and comp test each cylinder. And this vid is almost bang on albeit 1HZ but still same.
Hoping it's just a timing issue and not injector/pump failure/s and/or piston issues 😢.
Thanks for ya time bro 🤌🤙🤜
Ouch sounds nasty. Hope you figure it out
@@tinkeringtimmy4061 super sad face, have to replace 4 of 6 injector nozzles, and 2 full injectors. Apparently running at 8K+rpm on oil as the fuel has a carbonising effect 😂😂😂 at least the pump wasn't dead.
@@CCMiniBucks anyway we could talk further, i believe the same thing happened to me and having to do the work myself so any tips and findings would be super helpful. At this point I have everything apart and used a bore scope to verify no metal, I ordered a new turbo just to speed the process up, next step for now is to put everything back together and 🤞that it runs ok but I have my doubts 🤦
What engine maintenance video would you like to see next? Cheers

How to service injectors diy and put shims etc so don’t have to buy new injectors.
Oil Pump! My Oil pressure reading low. Anything on that would be great. (1HZ) Btw, if you click on the 3 dots on the right of Your comment, you can PIN it to the TOP.
Im in the process of doing mine, this is my first time dealing with shims and buckets. i got tdc measurements but i couldnt tell if i got it at 180. but all shims where off the lobes on other 6. do you reckon that would be ok? cheers
Hey tinkering Timmy, can I use a vernier caliper instead of a micrometer?
Hey Tim, great video! Just about to check my 1hdt. Do you need genuine Toyota valve bucket tool? or can you order cheaper one online? cheers
Thanks mate, I just ordered one off eBay. Just make shore its the same type and you should be sweet.
@@tinkeringtimmy4061 Cheers 👍
Hey mate, which valve shim tool did you use? Also do you know where I can find the FSM for a 1hdft?
just one off eBay, this video or the tool I use wont help with the 1hdft
Hello sir, how do I know my engine needs valve clearance? My 1hz has 4,00,000 kms. There’s a tapping noise coming from the rocker(tappet) cover during cold start and while reviving the engine over 2000 rpm. Could it be the valve clearance issue or the lifter making such noise ?
If you don't know when they were last done, check them.
Is the motor in the 80 turbo'd? If yes what turbo kit did you go with? Berrima Diesel seems to use the DTS kit with Mitsubishi turbo but some people don't think they suit a 1hz. I need to do my valve shims as it's over 700 k km's now.
yeah turbo, Ct26 style housing.
Tell me how often do check the valve lash ??..
I think Toyota recommend 30k miles/50k klms. From the info I have read, seems if you check the valves whilst doing your timing belt at 60k miles/ 100k klms is a good maintenance schedule.
How long it takes to adjust the valve clearance on a 1HZ ?
2 hours. Be shore to have the motor cold
No need for liquid gasket at the front and back of the valve cover?
Book calls for it, so yeah put it on.
@@tinkeringtimmy4061 cool wasn't sure and could not find any info online...thanks
If the exhaust is 0 what happens does it effect car?? Please advise me
The valve will get burnt up
