Sounds like a classic symptom of worn valve guides. As the engine cools, the
clearance between the valve and the guide increases, oil drips into the
cylinder and is burned off when started. As the engine warms up, the
clearance decreases and no oil consumption (or at least very little)
Had a '77 Landcruiser, my recollection is that Toyota 'copied' the old Chevy
stovebolt six for use in the Landcruiser. Your local machine shop should be
able to do a valve job for you without any problem.
