Sorry I know this has been talked about before but just wondered is anyone has any info or had experience of the cylinder heads that are available.

The problem has occurred within the 3 month statutory warranty period, but I get the feeling that the Toyota dealer is having a bit of a wriggle and I'd like some information as ammo if they start to argue.

It stated to idle rough, first thought was bad fuel/pump/ electronics, few minutes later temp shot up so I shut it down. Leaking water into number 3 cylinder.

Any info appreciated Hi I realise your original message was a while back, but I thought I'd drop you a line anyways! I have a '00 GXL Prado I went to get my 1KZTE head serviced at a reliable machine shop in my region and they denied me. Instead I had to buy a new head which was over $2000. Apparently the manufacturers went as skimpy as they could with the wall thickness in the casting of the heads to save money.
This doesn't leave any room for machining to be done and to go on to be reliable - they are high compression and need the full wall thickness. This bloke said you wouldn't get to the next town as she'd crack the head and die if I got him to machine it.
He's not the kind of bloke to just say stuff like that either - he's a tradesman, not a salesman! I don't think you are on your own with a cracked head on a small japanese diesel (not only prado's), but i reckon you were real unlucky being only just out of warranty.
I hope she's going strong for you now. Either that or she's someone else's problem now! Cheers!:) Mick.
Realise your message is over 12 months now but I have same problem and wonder how you got on getting any documented statements about weakness in Prado diesel head walls. Mine over heated suddenly and diagnosis was cracked head.
All other cooling components tested ok. Head testing claimed internal crack between coolant chamber and exhaust valve port. Extended manufacturers warranty claim being denied because 'heads just don't crack by themselves'. But according to reliable mchanics in specialist 4WD centres this appears to be common occurence for this model - and supported by views of others on this site. Where do we get documented evidence that this is a faulty component, not caused by a failure of some other cooling component? I have seen this 3 times before (customers rides).
Good luck trying to find any documentation stating pre-existing issues with the 1KZ heads. The 1st head we ever did 2001 (dealership), we did it 3 times as the head was skimmed and tested (cold) ok. Fitted and once warm bubbles through cooling system. Got the machining company (i'll call them EM) up to check before restrip (they had not seen these heads before). Gave back to EM, and all was ok, just slight warp from removal, so reskim slightly.
Same thing happened. Toyota aust couldn't/wouldn't give us any info as to what to look for, so checked out the forums (back then), to find it had happened before elsewhere in the world (NZ from memory). Then we found out that if the head was heated to operating temp, then checked, that we had a crack behind the pre-combustion chamber. Once we found this, toyota were more forth coming and supplied a new head.
Fitted up (customer was:evil: over time taken) and problem solved. The next 2 vehicles, we had EM check heated heads and both the same problem. So we got new heads (still under new vehicle warranty). Hadn't seen any after about 2003, so hopefully they fixed the cause. This is a post which maybe someone could help with - otherwise it may at least help someone else. I have a 2003 diesel Prado bought from new - done 105,000 kms fully serviced t/out. About a month ago, while starting a holiday, the engine starting overheating while towing a caravan after 150km.
The cause turned out to be combustion emissions getting into the cooling system causing coolant loss via the radiator expansion tank. Took to Toyota dealer who did TK test and found no problem. Had cooling system completely tested, repeat of TK test (I now know is pretty u/s anyway.) etc - no-one could confirm the problem - assumed radiator cap was the issue, took off again with new cap - but same problem at 150 km. The actual sequence of events with Toyota and other mechanics is too long and frustrating to recount. The upshot is that no-one has been able to diagnose the cause of the problem.
No water in oil or vice-versa. Turbo taken off line from the cooling system - combustion gases still entering cooling system. The head has been off twice, pressure tested in heated bath with dyes, ultra violet light 3 times - nothing. Cylinder 'liners' (they are not actually lined) seem ok from visual inspections. No signs of scores or marks on the head gaskets.
Two noteworthy events during all these diagnostics were 1. After hard run, while at idle, copious steam began pouring from ehaust pipe but engine seemed to run normally - haven't been able to repeat this event since 2. After hard run, next morning with cold engine, taking the radiator cap off led to very obvious release of compressed air. It seems to me that there is a hairline crack in the head that only opens up when the engine is actually operating but closes very quickly when engine cools.
I can drive the vehicle as hard and long as I like with the radiator cap loose so it allows the gases to be released without throwing coolant, without a hint of overheating. At this stage, I am getting a new head (Chinese - because $$$'s are now mounting up) put in, in the hope that it is a head issue that hasn't been able to be confirmed from the available out-of-vehicle tests. If anyone has any ideas on the problem, it would be appreciated - otherwise I'll do another post when the new head is fitted and I know for sure whether it was the head or not. Seems the old 1KZ diesels are suffering a contageous outbreak of cracked heads. After months of trying work out why I had an intermittent rough idle on cold start which involved changing glow plugs and the primer pump assembly, we find she has a cracked head. Seems there are several cracks in all four cylinders. The thing I found surpsrising is she never overheated, lost power, etc.
Although one of the symptoms included a very thirtsy radiator when inspected, there was nothing to suggest a head or gasket problem in day to day use. So after 167000 km and around $4000 to get it replaced it should all be good for another few years. Hi, I have a Mar 2001 1KZTE that just suffered a cracked head. It cracked underneath No4 cylinder pre combustion chamber. Vehicle never overheated, has done a lot of towing, never used all, no change at all in performance.until I heard bubbles in heater (in Alice Springs).
It was blowing top of radiator empty into coolant bottle. Limped to Darwin and got it fixed by McIvers (Peter - good guy)head reconditioners. They sourced a new bare head and fitted my bits to it. Mechanic Dave Cooper did the spanner work (also great guy). All up cost - $2950.00. Now headed back to Perth. Sap software full version with crack.
I think I have the cracked head too.:cry: Water temp is always been normal and it still is, but yesterday when hot it started to make steam and bubbles when radiator cap is taken off. When cold, everything is normal. It is started poorly some mornings lately (makes smoke and start with 3 cylinder few seconds). Maybe there is hairline crack in some cylinder and leaks water in it. I have added 2 liters of water within 2 weeks now. What do you think about these cheap chinese heads? Worth of trying?
David Pitt, did you got it installed? KZJ90, I didn't notice any drop in performance in fuel economy either. Had this constant cold start problem that cost me hundreds in wasted glow plugs and the fuel filter pump assembly. It wasn't until I told Toyota that something was wrong and they needed to find out that they discovered the bubbles in the water and found the hairline cracks. Without knowking what was wrong at the time I towed a caravan from the Gold Coast to Adelaide and back via the Oodndatta and Birdsville Tracks, did Big Red, the development road and back via Charleville.
It still pulled 100 KPH in 5th with the van on! Stilll drove around for another 6 months before they found the cracks! So don't be too worried, if it were a Patrol 3.0 Td GUII 'hand grenade' there would be reason for concern. There are plenty of Chinese heads that are bad, and some that are good. China now makes engines and components for many car companies around the world, Honda included.
There is a guy selling on ebay, as well as conducting his regular engine reconditioning business. I have purchsed heads and other stuff from him, and the quality is good. I think he goes by willyengines or similar on ebay.au. Virtual audio driver windows 10. Remember, it doesn't matter how good the head is. If you go with a cheapy gasket, or do something stupid like reusing head bolts, or not fixing the cooling system, the head will fail. Just becaused a head fails, doesn't mean it is a bad quality head. Remember, it doesn't matter how good the head is.
If you go with a cheapy gasket, or do something stupid like reusing head bolts, or not fixing the cooling system, the head will fail. Just becaused a head fails, doesn't mean it is a bad quality head. The gasket was good quality (made in Japan), new bolts (btw. Toyota gives permission to use old ones, if they are thick enough), cooling system is at very good condition, no towing, no highway speeds, no immediately shut downs after long term driving. I don´t understand why you say the head which is cracked after 4 months usage, is not bad quality head.:evil: I think it is crap, not quality at all (athough it looks fine). I know they can make a good quality product in China, if they want, or somebody demands. But aftermarket parts are what ever happens to be.
Chinese heads can be ok but they still need to have the pre combustion chambers looked at as they never get the height rite on installtion it also wouldnt hurt to change them to stein brand as the chinese pre co chamber are not too good it also pays to get the valves re seated and a better skim on the head,and with gaskets use genuine Toyota head gaskets and always after replacing a head find out what caused the problem originally, to much boost? Check the cooling and fuel system and allways change coolant with genuine coolant ( as you can not get much better )and NO additives on the recomended intervals as well as the oil. I have allways done the coolant change reguarly and NEVER had a problem with my vehicles over heating:wink. I've got a Prado 2002 with the 1KZTE and basically all the symptoms you guys have said is whats happening to mine. I bought mine with 310K on it and less that 6 months and only a couple of long trips it appears the head is cracked.
Dont know if the previous owners have changed it or not as theres nothing in the service book about it. Anyway I'm changing mine over week after next. I'm getting the AMC brand just like Theroo advised. I spoke to the guys at SMS Diesel and they advise against the chinese made ones too.
1kz Te Cylinder Head Crack Symptoms List
Its not a huge difference in cost with a complete head, gaskets, bolts etc for $1450 for the chinese one and about $1550 for the AMC one. Going to change the timing belt, water pump, tensioner and idler pully while I'm at it. Hi all, We have a 2005 120 1kz with about 250,000 only had it 12 months and it over heated the other day to just below red line. On inspection the coolant was low, overflow tank empty:???: I've had it pressure tested and its holding no probs. Tk test tomorrow.what ever that is. It used bout half a liter of water driving the 30 ks to the mechanics but no obvious signs of leaks and bubbles in the radiator. Question is.is there any other ways of diagnosing the problem without actually removing the head.
Mechanic said there was a slight water stain under the water pump but given the quantity of water I'm losing we doubt it the cause. Any thoughts. Water was not obvious in the engine bay and there was no drips underneath which baffled me initially.
Mechanic started with pressure test - no drop. Then tk test - nothing. Mechanic took it for a run and on return felt the end of the overflow tube (the little black elbow bit) which was a bit damp. Ordered new cap, took it for another run and water level didn't drop.happy days. We were freaking out at the potential expense and family been stuck at home with no wheels. My 3 year old gave the car a cuddle when i got home.
Cylinder Head Repair
Love our prado. I hope that was your problem but I'd still be keeping an eye on the level.
1kz Te Engine
I had the TK test done on mine and at first showed nothing. Had thermostat replaced, probed and rodded the radiator, checked viscous coupling on fan, new radiator cap. Was still coming out radiator cap into overflow bottle then would overfill that then spew out on the ground which indicated pressure but from where?? We had done TK test. Then figured while running around town no issues what so ever get her out in the highway/freeway doing 100/110/120 (tel:100/110/120) then pull up she'd be bubbling and gurgling out the overflow. It was at this point we decided to do the TK test (bit dangerous being hot but wanted to be certain) bingo come up showing exhaust gases in the test which indicicated either cracked head or damaged gasket, I knew which one is was going to be. Cracked head 4k later.
Reason the TK didn't show up first time was engine wasn't hot enough just running around town, give it some and get her working was enough for the head to expand enough where the crack was and let the gases flow lol. I hope yours is as your've pointed out and was just the cap.cheers Steve. Gta vice city downgrade.

Hi guys1kz Te Turbo Diesel Engine
1kz Engine Problem
I have a 03' hilux with a 1KZ-TE engine and need to fix a cracked head on the old girl. Does anyone know of a good place to get a recon head or even a new one ? A lot of people have told me to patch it up and sell it but can't bring myself to do that lol spent alot of time and money on it over the years and want to get it back going again. It's got long range tank, ARB bar work all round and heavy duty bull bar, hella spotties, UHF radio, ARB canopy, cargo draw system, rhino roof rack, water tank, Dual battery and OME shocks. I have lots of plans for more mods in the future and trips to suit but need to get the motor back in good working order. I'm in Perth WA, if anyone has advice or links to other sites that would be great.
