just some random observations...
Glo-plugs.. Don't warn the seller? of your approach, so they don't get to
warm the engine up before you get there.
Injector tips can be a problem with high milers - puffy smokers at idle
might telegraph that. They also develop a distinct bell-like sound at
idle with rooted injector time.
Most of the other stupid little problems they have seem to require a
spanner or two - like problems with the seals of the pump.
Oil where air should be - one bolt for that.
Diesel getting past the front pump seal is a little harder to check:-)
And the usual ****y Toyota trick of letting the diff oil into the wheel
bearings. That is turn lets the swivel pin bearings burfield joints
designed to work with Grease stuff up and so on and so forth.
Look for oil seepage near the outer seals/FW Hubs.
They are also justly famous for pumping all the oil out of the transfer
case - which of course they hide in the gearbox. Result is a ****ed
transfer case and gearbox seals, for that matter.
There's a operational cure called a heart bypass done by some in which a
sturdy (should be Hydraulic pressure hose) pipe and fittings set is
adapted to drain oil above the gearbox filler back to the transfer case
filler.
Works a treat - one of them on the machine is a sure sign that someone
gave a **** about it. Or was burned for transfer case work in the past.
Some high milers dump too much oil past worn rockers making the engine
conk-out just after starting due low oil pressure.
They can duplicate that problem by having a stuffed timer relay, too.
Damm hard to tell the difference because Toyota appears to have over-
damped the oil pressure gauges.
BTW if you get a chance, get at the oil pressure sender lower RHS of the
engine and yank the plug off. (bit hazy n whether it needs to be earthed
to stop the engine - I think not - that O/C does it - but you get the
idea. The engine should either stop, or not start if it was stopped when
you played. Yes, believe it or not they do have a low oil pressure cut-
off system and it's not hard to defeat to disguise a rooted mill.
The brake master cyl will most likely be stuffed - see other thread:-)
Since they don't make much power anyway, it's pretty hard to tell of they
are clagged out, but a little hill should see whether the engine actually
hangs on it's torque-peak properly - only a good 2H will do that.
Other than that, they're pretty right.........., well, I hope so.
BTW if the things you look at have the later HZ engines and there is ANY
sign of their being overheated, walk away. Fast. From what I'm told by
those who work on them they're not a successful repair proposition if
they've been cooked.
