Man this is making it around to every sub-forum aye... That's awesome, although I'm so jaded now days I doubt it'll do any good, but hey, what are we gonna do, NOT try??? Nah, that's boring...
Per the 3.0L/ZD30 Patrol's: As someone who's lived in places where these trucks are prevalent (Australia) and had lots of experience working out in the bush/leading 4wd trips with them in group, there's no "myth" about the 3.0L "ZD30" Diesel engines to be busted... they are, quite often, "ticking time bombs" and with the Auto-tranny behind them, doubly so.
I've not only seen it up close and personal but I've had to deal with the consequences of the failures out in the middle of the bush in 125*F heat when my own and others trucks, many of which had LOTS of aftermarket "hop up" gear on them (some TD42 Patrols were pushing BIG power, my own 1HZ75 Ute had an aftermarket Turbo and we were all loaded down for multi-day/night trips) and none of us had much more then a little heat soak when sitting in 4wd working through slow terrain or whinching. The ZD30 is simply not an engine I trust. I kind of wonder if part of it is down to the same issues the Toyota 1KZ-TE has from the factory: They're tuned them for the lowest possible NOx emissions, meaning the timing gets retarded and fueling get's upped at the IP leading to overheating, poor econ/power and more smoke/soot and eventually all sorts of problems. Either way there are still heaps of other issues with the engines architecture and when you've seen the failure rate I have up close and personal (constant "limp mode" engagement with no way to correct the issue that we could find, multiple turbo failures, snapped/broken cam's and a crank-shaft, lunched Auto boxes, a window-pane'd block at one point, HG failures L/R...), it's shocking, and def. NOT what I'm used to with Nissan's in general.
Still, I do love Patrols, the 260 series and the later Utes (like the portal'd monster linked above :drool: ) are just plain awesome... I'd just take mine in the 4.2L TD/Manual trans. flavor (I know shocking right). Like all rigs, there are the ones you want and the ones you avoid. The ZD30 powered trucks are, for me, a big "avoid".
