Toyota 2H engine advice req.

I'm checking out a couple of 75 series Cruisers tomorrow morning, both 
(presumably) still have 2H diesels. Apart from the obvious (such as test 
driving them), does anyone know of anything to look out for with the 2H? 
Any common problems these engines are prone to and if so, any way to 
check visually without resorting to pulling them apart?

I suppose ditto for the rest of the drive train as well ...

Although I haven't driven one for nearly 15 years, I used to drive them 
daily for many years, so any odd noises etc should be easy for me to 
pick up on (I hope!)


Tnx,
