The 1KZ-TE engine (and head) is as reliable and well made as any other good Toyota engine. There's an issue with 2L-T heads cracking as well (although you don't hear about it much now due to them being quite old).
As mentioned above, a lot of it comes down to poor maintenance, failure to ensure coolant is fresh and topped up and not looking after the radiator. As correctly stated above, the cure for it is to fit a larger exhaust. Heat build up in the turbo (not being able to escape away from the head) is the main cause of cracking. Once a bigger exhaust is fitted, no more problems. Driver_studio1, May 3, 10:39 am. Thanks for the replys few good insights and ideas.
I can not comment on how it was driven as I was not there 99.9% of the time but I don't think it would have been thrashed or driven in a stupid way as the guys not like that but only he knows I guess. In this case it isint the cleaness or conditon of the cooling system thats for sure! As the litttle radiator was checked, cleaned & flow tested and the main radiator was re-cored with a brand new core also at the same time an aftermarket trans cooler was fitted and the viscous fan is in good condition. Still the fact is the same thing happens to genuine heads very often but thats an interesting thing about the 'plenty of engine builders have shyed away from STA heads' I would not be surprised really I guess so maybe in this case thats all it is.

Main problem with all of the 4 cyl turbo diesel engines is that the cooling system is just big enough for the engine under normally load and operating conditions.All you need is a slight cooling blockage, a viscous that is a bit tired, a slightly restricted exhaust or when you really start to work the engine and everything can't keep up.The heat builds up faster than it can manage and the engine overheats.There aren't many engines out there that can stand being overheated.
