The chances of a 1KZT head going is probably about the same as a 4M40. Definitely not as bad as a 2LT or a 4d56 for example. It all depends on how it was treated before you got it, how many hours on it, and even what vintage it is. Like the 2LT, I think the 1KZ's got better as time went on. I think it's wise to consider the possibility of having to do a head at some point however. Account for it in your budget. I'd say on average, the 2LT's needed cylinder heads within 100,000km, where the 1KZ's seem to last more like 200,000km+ before needing one.
Thanks. I was hoping I was falling victim to the hysteria. I always drove the 4d56 and 4m40 conservatively, and watched the egt guage like a hawk when towing. Nice to know that similar behaviour with a Prado will likely yield similar results. Although my wife's new to her 100 series will get towing duties now, so whatever I get won't have to anymore...
Thanks @GTSSportCoupe . Your advice has already been sage in many threads.
