All that maintenance is great guys, but my 92 Classic (3.9L) has basically 200k miles on it still runs very well, has NEVER had the trans fluid changed since the first time under warranty, and never slips or doesn't go into gear. We put the Land Rover grease into the swivel balls on the front 40k ago and never a problem. The CV's and silver balls are original. We checked the steering full lock before we bought it no clicks. 4x4 system is perfect. We change the oil every 3k miles always and use Lucas Oil Stabilizer since the truck does use some oil. We put new but standard copper plugs into it, but has the same Rists Suppression plug wires on it it has had forever. New cap / rotor 30k ago. We've replaced the entire exhaust system one piece at a time from the headers back including both cats but the car has the original O2 sensors in them. No check Engine Light ever (it does work)
Radiator is original / no problems.
Really, these cars can take quite a bit of abuse mechanically, but I recommend change the oil sooner rather than later even when their young.
I live in a brutally cold climate in the winter (has been -20F for the last week) with lots of snow and truck is canadian model with DRL and block heater which we use. It gets to 90F in the summer or more here too, though, so truck sees the extremes.
The brakes need plenty of work, and the truck needs a headgasket, and of course is fairly clunky. But very reliable and tough machine.
I've heard the 4.2L LWB's can have premature engine failure due to shifted cylinder liners, and its true some have new engines at very low mileages. (DAP says an LWB w/ original engine at more than 100k miles is living on borrowed time) Others have said they have never heard of this problem and there are, in fact original LWB's with 300k on the 1st motor.
Change the oil, don't let the car overheat, and don't let the RPM's get low on a long hill (don't let the car dog) Shift into third, or even 2nd gear. It is much better for the engine to be at 4,000 RPMS up a long hill then at 2300 dogging up the hill. The engine gets much hotter and you can shift a liner. (says RPI Engineering in the UK)
