Im wanting to buy a blown 1kd engine to rebuild with stronger internals more for reliablity compared to the standard ones that can sometimes crack pistons.

Just chasing anyones experience on where I can buy a motor from? And roughly how much It might cost

ebay has a large selection of working examples, but I've never looked for blown motors

Try the local wreckers/scrappys and buy it for scrap value alone, if the motor is dead, they are just going to bin it.

I sold mine fro $500 after about a month of been advertised it only had 155k on it

That's a cheap engine for a handyman to rebuild! Probably just needed new pistons and a cylinder hone to make it alive again

Or at the wreckers, they degrease and wash the engine, and hey hey it is "Re-Conditioned"

yes I once had a Chrysler 125hp outboard with a cracked cylinder and it still ran ok, told a mate and he bought it cheap as a fixer but used it for a couple of years before it exploded. After that I had 150xs Mercury motors which ran forever at 100mph

Don't forget that it must also have the special "reconditioning paint" applied,

"reconditioning paint"
Hhmmm, let me think now, isn't that just the degreaser with a bit of food colouring added?

Cracked piston 3, A decent gouge out of the liner. I did the math on a rebuild and decided a new long block with injectors was the way for me to go, Low down time and having a contact at a big sydney dealer made the price very close to a DECENT rebuild with new injectors.
Thats coming for a bloke that works on engines for a living.

Ah I see, yes it's definitely worth doing the math before committing to a rebuild.
Any idea why the cracked no3? Chip?
I have heard that Toyota had a large batch of 1kd crate engines going cheap a couple of years ago. Probably leftovers from the old model when the new one came into production. Just in time manufacturing does sometimes have a downside if people stop buying the old model when a new one is in the early stage of production. Personally I'd rather buy the last of the old model rather than the first of the new one.

It's a common occurrence as you are probably aware, Yes is was Tuned with a different turbo, Intercooler etc.
I don't for one minute believe it was any fault of the injectors as they tested fine when doing the timing belt just 5000k earlier. Another reason I went new was the Engine number range of the new block fits in with the piston and injector upgrade that the Toyota bulletin of Europe that I'm sure most are aware of.

For those that are interested the Engine ASSY, Partail from Toyota PN-19000-90690 come with Cylinder head, water pump Injectors and fuel pipes. Trade price at a local dealer was just under $7500, Lets just say they still make a good dollar when selling at trade compared to what I managed to get it for.

You also need to order glow plugs as the 1kd has a habit of getting a good hold of them.
Spiggot bearing if manual
Intake & exhaust Manifold Gaskets.

Thanks davo, I guess it adds to the suspicion of the no3 piston being a weak link hence the update in 2015 engines. So are you fitting the different turbo and tuning the new one
Even at the trade price it's probably a safer bet over a rebuild. Especially if you factor in the cost of new injectors and update pistons.

Well I have recently found one that is seized due to oil starvation

Dont know what the internals look like. Im hoping the block is ok

Im going to completely gut the motor and replace and refine everything

But I need another opinion,

Seized motors are ok to rebuild?

Depends on how seized and what the bores look like. It's possible to rebore if the damage isn't too deep. Not sure if it's possible to resleeve.

As Gipsy says, it all depends on how / why it seized in the first place. If it was due to some kind of over temperature issue (NOT just a boiling engine), then you run the risk of glazed High-Carbon components, or maybe warped cast components or even buckled / warped mild steel components.
The list of risks is endless, but the enjoyment you will get as you solve each and every issue on your list ... "Priceless".

Correct Rob, risk is endless but the enjoyment (experience) is PRICELESS some people try to convince me (unsuccessfully) that experience counts for nothing but attitude is everything! I'm not sure about that, experience is always the best teacher
That, of course is if you actually learn from the experience... Some folks never learn from experience

I hope LHooley keeps us updated on how the rebuild goes. It would be 'priceless' to benefit from the experience as told by the OP.

Stripped the motor down and the good news is that is the block seems really good, Unfortunately theres been some damage to the crank shaft, supposedly where it may have failed.

But because the blocks good, thats a win for me currently.

Now it is the first motor will be rebuilding myself (Ill have plenty of assistance)

But sourcing everything will be next years job.

Funny story with this motor..

So it got serviced by toyota and they didnt tighten the oil filter. Thus motor ran out of oil and starved.

After fighting they replaced the motor but stiched up old mate with labour costs.

Talk about loyalty, Theres another reason why i hate dealerships

Good outcome, a crank and internals should be easy enough to find. You will need to carefully assess the conrods etc. to make sure all is ok there. Pistons and rings, go for 2015+ euro type, they were upgraded by Toyota.
There's a lesson there for all of us who do our own service, check for leaks... And even (ESPECIALLY) if a dealer does it, check it's all been done properly. Invariably it's the apprentice who does the oil change and there's very little supervision to check the work. That's why I do my own service, that way I know if it's been done properly. If you want something done properly, do it yourself! It's also worth noting if the oil pickup is clean, leaking injectors seats cause blowby causing the pickup screen to clog... Then seized engine! Don't always believe that the story was true, seizure is common on early Kun26.

It's amazing how so many people get their vehicles serviced and never lift the bonnet until the next service is due. I would be lifting the bonnet every time I drive the vehicle since things do go wrong, and I imagine 7litres of oil from an oil filter would be a little obvious It's always a good idea to look under the car frequently because oil leaks are s easy to spot.

The pickup was spotless when I pulled the motor apart yesterday, The injectors were pretty caked but nothing too bad.

As for the mods..

Theres some modified pistons you can buy through a mob called G&L Performance

They do a modified, forged, coated piston upgrade which fixes the risk for cracking.

Currently the plan is to also

- Stronger pistons
- Balance shaft delete
- Hi-Flow Turbo

And it should fly for 500,000kms
