Yeah Stewart-the sandwich type setups do see the full engine oil pressure-and hence my inherent suspicion of such set-ups with flexible hoses. Purely because you are exposing yourself to the risk of a burst hose in the critical engine oil feed circuit. I tend to refer to such risks as those which are relatively easy to avoid.
If you are looking at a remote oil filter setup, I'd be inclined to do the following-
Mount the oil filter itself somewhere on the engine where it is relatively easy to access. Put the plate on the motor, but get some screw in fittings for it and run steel bundy tube from the plate to the filter using brass compression fittings. (1/2 works fine-order it from a hydraulic supply shop or an automotive brake workshop. Pretty damn cheap.
(I say mount the filter on the motor as if you are using steel bundy you don't want the engine moving and the filter staying still-crrraaaaaccccckkkkkkkk....ssspprrraayyyyyyyy y....grind grindgrindclunkclunkclunk etc........=-)
Once this is set-up-find an outlet from the engine block oil circuit. Most engines will have a decent threaded plug in them somewhere where a machining process has been carried out to create an oil gallery.
My guess is that a 1J should have a main oil gallery running from front to back like an M series with a big 8mm allen head plug in it. If it isn't easily accessible, there should be somewhere to tap in without needing to dril anything.
Once you have access to the main circuit, grab a bypass valve from a crown (or indeed get one from a hydraulic shop-but the crown one will be less dollars) and feed the oil to it. This will be at full system pressure, so don't skimp on the braided teflon hose, or again, use steel bundy and an engine block mount (much cheaper.......).
Then feed a flexible hose from the valve to a oil cooler, and then back to the sump. The oil circuit post valve will be open to the sump and so will not be at any appreciable pressure. As long as you hose can stand up to around 100-120 centigrade you are laughing. Just have a look at the std oil cooler return hoses on an M series! Absolute garden hose-and after 30 years it's generally still intact.
From my experience, the 72-75 crowns have the oil cooler set-up, although the later ones may have it as well. You'll recognise it as an alloy item bolted onto the block near the oil filter, with a hose going to a small rectangular cooling core next to the radiator and a return line going back to a banjo fitting into the sump. When you go to a wreckers, act dumb and don't let on you know what it's for, ("it's for my dad" or some crap), otherwise the price can go up. Even the actual cooling cores on the crowns are very good-they are a proper envelope style core as opposed to an el cheapo tube and fin type.
Anyway-take it easy, and I'll get some prices from a hydraulic shop near me for teflon hoses. My guess is that they shouldn't set you back more than $150-$200.
