Brilliant. Thanks a million for sharing your knowledge !

Another excellent bit of info on the 1KD piston cracking issue, awaiting the next video on the Injectors..

Mate loving your videos. Cheers, Rik.

good on ya for imparting quality content mate

Great video and very good experience that actually makes sense. Having been through this costly exercise myself before, the million dollar question is of course how to fix or prevent this from happening again?

In the 1990's we were told to scrap the Yota exhaust system and replace it with a larger diameter piping system to open it up to help breathing freely.

Great explanation...thank you!

Yes , makes sense to me!

Loving my V6 Hilux! 1GR-FE is king.

Here is a tradesperson who knows what he is talking about. No misinformation. I suggest you listen to the truth about the 1KD pistons. Long hauls, high rpms and heavy loads cause cavities on the top of the piston. If a cavity develops on the edge of the combustion chamber this then will lead to the hole cracked piston situation. Nothing to do with the injectors as this was tested by Toyota engineers in 2014. The findings were the pistons are to blame for this failure, not the injectors. Toyota's own words.

Do you think the craze of bad tunning + Chips is making the problem more prevalent?

What a well educated explanation of this prob, I just bought my first Hilux 2011 hl2 D4D (think it's a KUN25? Noticed rattling noise on acceleration so bought a bottle of injector cleaner(fuel tank additive) but it seems to have gone a bit worse? It's around 1500-2000 rpm any advice plz.

Hello Pete. Great videos. Well done. I just had an 15reg hilux with 70k on the clock. in with piston skirt failure. Is this something you’ve seen? Many thanks ben

This isn't a peripheral engine problem but a direct piston cylinder and one would have expected toyota in their controlled engine evaluation would have picked up this issue

Hie What are the mechanical effects of not installing balancing shafts on a 1kd block and blocking the oil galleries by turning the back bushes.

What is the cause of the crack happening?

how many 2005-2006 1KD's have you seen?

A good video but why hasn't Toyota fixed the problem with a better designed piston like a real diesel eg cat Detroit Cummings ues Two peace piston with steel crown and gudgeon pin with a aluminium skirt?

Hi good day what about the 2kd engine any information on them ?

turbo timer. or just let it cool down before you turn it off?

turning off the EGRsystem can speed up this process?

whats the solution?

Do you ship to the U.S.?

Would a EGR delete help prevent the issue ?

Is this just post 2006 engines, when there was a piston re-design?

Great video mate. Cheers for the info. What would be the solution then? Is it something that can be avoiding by modifying the injectors? Would be great to see a correction for this if there is one. Cheers again mate!

So is there a replacement piston that doesn't have this thermal expansion cracking problem?

Sir, what's the fuel consumption on 1kd engine in 2007 vigo (approx)

Do these 1kd engines have removable sleeves or is it just the block

When the pistons crack, is it usually just one or can all 4 be effected together? I have a prado 120, low mileage with no compression on any of them? Cheers

1kd vs 1gd whats your thoughts for someone looking to buy a prado

5L was the best hilux engine notvthe kz and this new shit,same with the best were 1hdfte and old 12ht landcruiser engine, I personally own a 300,000 KS 2009 79series landcruiser I use 5w40 full synthetic castrol engine oil and rhyco oil filter, best thing to do with the v8 change the engine oil at 8000 max don't go long

So let me get this straight.....1KD stands for 1Killing Diesel. Would that be a fair enough description? Remind me never to buy another Toyota.

Typical over rated Toyota rubbish
