Diesel Compression Test or Leak Down Test? Toyota Land Cruiser 1HZ 1HD-T 1HDFT 1HDFTE 

clearest explanation i've seen . want to see the leakdown test too.

Man what is your background? You seem to be able to explain things really well, great work👍👍👍

Definitely a great vid mate, though you might confuse some people about when and what causes combustion in a diesel engine, great explanation other then stating that air "and fuel" enter the combustion chamber via the Inlet port and valve, you also said that eventually the compression causes combustion, while almost true you should mention that the point of combustion is actually controlled through injection timing and that only air is introduced through the inlet port and valves in a diesel, just seems important to mention is all, not having a go by any means, cheers

Well I am happy with finding out what is wrong with the donk, so whatever you publish, leading to that end result, I will watch! Cheers and good luck.

This was so friggin informative man. I completely understood everything ypu said and I find it difficult to tie my shoelaces 🤣. Instantly subscribed and will watch the rest. 🏆

Yes - love to see a leak down test.

Very informative video, thank you for posting.

Top info mate 👍 well presented

Tanks for a information.

Really informative video. My mates car is burning oil from cyclinder 1. I suspect vlve seal. Other mechanics have said low compression. This helps alot.

Well done! Thank you for sharing

That was sick! (Is that the term that is used these days or I am of touch - again?). Hmm, sounds like a series on tracking down compression related issues is warranted. Tackle the basics - where can cylinder compression leaks occur and how to test for each possibility and then, perhaps, an indication of which are exceedingly rare. I'm running an 4JX1, so not *all* your viewers are interested specifically in Toyotas :), so it would be general diesel info.

Thanks, great video

Top lecture, keep up

Yes please, a video on how to perform a leak down test would be great.

Can you do video of symptoms? So we can look and compare if something similar happen to us. Thank you ;)

Yes thanks please record a leakdown test

Great video mate, what lead you to check the compression, any smoke, rough idle or oil use? I have a similar issue, well think I do/did, two mechanics gave me different results. One was 180 and the other 520 was my happy 400k birthday surprise which I also had the valves check at the same time. No smoke, no oil usage, no rough idle and no blow by. Be keen to see the leakdown test.

Yes please do the leakdown video

Can u come back with the leak down test pls ?

a great explanation but can you also include in the diagram where the glow plug is in relation to piston and cylinder? and what does it do?

Hey mate, i didn’t disconnect the fuel 🤦🏻‍♂️.. but I got 520 psi all cylinders. Any advice would be appreciated cheers mate keep up the content and videos

Great explanation of “4 stroke”. Now i can pretend to know what I’m talking about when my son asks what the term means

Great video. What symptoms was the engine showing that led you to run the test?

Aww gee why doesnt anyone do a compression test on a HDFTE.......it aint anywhere on RU-vid

Great vid, hope to swap a diesel into my FZJ80 some day. Got my 7.3l powerstroke in the mean time atleast.

Hey mate, what compression tester kit is this? Finding it hard to find the right kit for a 1hdt glow plug size

Hey Great video but how long should i expect 1hdt will last

Also check out our leakdown test video here! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-e_x8NeXfvMM.html

Watched both videos. What was the end result when you opened up the engine? That would have made a great video.

Cool

keen for the leak test

This process is not the same for the 1HD-FT or 1HD-FTE as they do not have glow plugs.. the only way to test compression is to pull the injectors and use a special tester.

You wouldn't bend valves from hydrolic lock but piston, rod or bearing damage is pretty much guaranteed

Like to see that

My 1hz has 350-370 around that for all 6 cylinders. I wonder why its not 450+

🤠

Cant this be used as a leak tester as well?

What's you best trick for diagnosing a sick engine?
