Hi
I have a 1986 Landcruiser, which has got me from the UK down to the central
sahara and back without missing a beat, but on long runs has a tendancy to
somehow draw gear oil from the transfer box into the gearbox. This results
in the gearbox being overfilled, the first indication of which is the clutch
starting to judder. (i assume an overfilled gearbox starts dumping oil into
the clutch casing somehow).

There is a need to drain the gearbox every 5000 miles or so, plus of course
top up the transfer box with a couple of litres.

Any ideas on how to stop this problem????

Cheers... Chris

Check for a plugged vent on the transfer case and/or a worn out seal
between the trans and transfer case.

Thanks Mike

I have checked the workshop manual, and there does not seem to be a breather
installled on this thing... Perhaps I should get a drill out and make one!!
May stop sucking the oil out the transfer box..?

Ok, maybe I'll just leave it and check the levels every 2500 miles, until
things really start going wrong.

Mike is right. It's an easy afternoon fix. There *is* a breather there
and its likely plugged. When you have the case off you should plumb a
vent hose up under the bonnet.

Cheers,
Bruce
