Many years ago I remember a company was making a spin on adapter/spacer that mounted on the oil filter socket (for holdens) that had an outlet and inlet tube attached.
You spun it on, then spun your oil filter onto it.
From the inlet & outlet tubes you could run lines to an oil cooler, the oil came out of the engine, passed through the filter, then as it went back it was diverted to the out line to wherever, then came back in the return line to the engine.
I would like to know if anyone still makes these sorts of things (in particular for a 1HZ diesel lol)

Yes they are available, is it really necessary?
What you are doing though is fitting something that could fail and cost you your engine.
A friend fitted one to his troopy and all was ok until one of the hoses split pumping the contents of the sump on the road, by the time he stopped the engine was buggered and threw a rod out the side of
the block. No oil pressure at 100k's equals no engine in a very short space of time. He was then faced with being on the opposite side of the country in a remote area with no engine! A very expensive exercise.
If you do fit one have very good quality hoses made to suit by a specialist supplier, make sure that they are routed in such a way as to avoid any chafing or heat from the exhaust.
Another point is that cruisers do have a relatively large oil capacity for the size of the motor already, the sump is hanging down in the slipstream so does already receive some cooling. You are going to take that heat and put it up in front of the radiator which won't help an already marginal cooling system in a 75/8/9 series at least.
The same setup was also used to fit a second oil filter as
well so as to extend change periods.

yes most definitely have hoses made up by Hose Doctors or Enzed.
These will likely have a minumum rating of at least 4000psi, as opposed to around 100psi tops from oil system.
Best place to incorporate a cooler I would think is on the turbo oil drain as that would be the hottest oil and therefore the most efficient heat transfer. Obviously the oil must still drain away freely though.

Fisho64 the cooler will need the oil to be under pressure to flow through the cooler so the return line will not work except if the cooler is below the turbo.
I'd be very wary of introducing any restriction or a cooler into the return line though.

Putting a cooler on the turbo return line would cause less oil to flow through the turbo due to the greater restriction across the turbo. More would flow through the rest of the engine due to the slightly greater pressure of the oil system.

I do not know much about Toyos, but this I do know.
In some markets Toyota fits an oil cooler, certainly did on the old FJ62 in Saudi. But it was not to an external cooler. It is a sandwich between the filter and
the block, and has coolant hoses to and from which go to the Radiator eventually.
I would be very surprised if there wasn't a model diesel in australia which didn't have one, most probably a turbo diesel. It stabilises the oil temp at rad temp, so it is neither too hot or too cold.
Have a look at a wrecker or dealer.
