1hdt 1hz Valve Clearance Adjustment Landcruiser 80 Series | Engine Maintenance | 

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.

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 Dave Captain (FB)

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 🤌🤙🤜

What engine maintenance video would you like to see next? Cheers

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 mate, which valve shim tool did you use? Also do you know where I can find the FSM for a 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 ?

Tell me how often do check the valve lash ??..

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.

How long it takes to adjust the valve clearance on a 1HZ ?

No need for liquid gasket at the front and back of the valve cover?

If the exhaust is 0 what happens does it effect car?? Please advise me

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
