Hi Pete, welcome to the fold. I own a 1992 LJ78 and am slowly kitting it out for overland adventures. In the meantime it is my daily drive and fun toy for a bit of green laning once or twice a month. I'll try and help you out as best I can with this motor you're interested in.

There is a 78 on fleabay - item 200505511407 , which looks and sounds in good order
It looks and sounds great, the seller has 100% feedback so there's a good start.

...but there are a couple of bits of info....I'm guessing its leaf rear and coil front, I need more comfort than, say, a series 3 landie, but accept that £2k isnt goint to buy me all round coils!
...errr, actually, you'll be surprised! Coils front and rear with a solid front axle
It's perhaps not as comfortable as a road car but it's damn close..

That one is a jap import, so I need to look at undersealing & underside rot, any other issues other than oil leaks, transmission clunks et.
6 years of UK roads shouldn't have had any major effect unless it's been mistreated (eg; driven in seawater and not washed for days afterwards). The resistance to oxidation of the metal on this is excellent. I'm just starting to see some small patches of surface rust on mine, it's been in the UK since Dec' 98 and never been undersealed. If there is any rust I hear it comes up through the boot floor first, so check under the carpet in there.
Other than the usual checks, know that these things are susceptable to head gasket problems, so check for "mayo" on the oil filler cap, low water level, white/grey exhaust smoke etc etc. Annual rad flushes with Toyota "red" coolant should keep the demons at bay.
The lowly 2.4 can feel a little underpowered for some, so make sure it will do everything you ask of it. Mine can get a little warm towing loads up long hills but it has been plenty powerful enough for most of my requests. There is also a 3.0TD version, known as the KZJ78 which was available from late 1993 to 1998 iirc, although (iirc again) this runs the same cooling system as the 2.4 and as a result can overheat easily leading to a cracked head if you're not careful.
If it has electric front hubs, check they work when the button is depressed and the ignition on. Leaving the t-case lever in 2H try to turn the front propshaft, it should have a small amount of play but if you can turn it right round then the hubs have not engaged. They are a constant source of pain with the light duty 70 series and tbh best replaced with manual hubs. I have permanantly engaged mine as a free alternative.
Off the top of my head I can't think of anything else to look for, just the usual stuff that you would with any car.

Again, I'm guessing it has a low box and central difflock (similar to a S3 landie setup)
It runs part time 4wd, with 2wd high range and 4wd low range selectable on the transfer lever, and 4wd high range selectable on the dash. The "centre diff" if you will, is constantly locked when in 4wd. Obviously the front hubs need to be engaged to get 4wd.
I hoped I've helped, good luck with your search
Jim.
