The stock oil filter can absolutely cope with the pressure. Cartridge type filters are all the rage once again. I have several 4JJ Isuzu Diesel engines with Cartridge filters, and so yesterday when I serviced my late automatic mini with the Luberfiner filter that my heavy duty parts supplier can get overnight, I had a chance to wonder about the very few improvements Isuzu made to this system. It is simple, and it works.

K&N oil filters can cope with the pressure.

The oil pressure shown on the gauge is the pressure in the oil gallery for the engine, not the gearbox.
As I understand it the gearbox pressure is much higher and a spin-on filter cannot cope with it.

If you are referring to 60lbs as the engine oil pressure and not the transmission oil pressure your readings are not accurate to what pressures the transmission creates.
Someone who posts here who was in Japan had a spin on conversion done and i believe used a Toyota set up.
A remote cannister upright set up may be an easier option.

Hey Mike,

You might look at the Triumph TR3/TR4. They use the same long canister filter as the Mini Auto and the canister looks to be the same size although I have never had the two side by side.

Moss Motors lists a spin-on conversion kit for the Triumph TR3/TR4.

I have been considering an attempt at converting to a spin-on as well and have been looking for posible options.

Keep us posted as to which direction you go or what solutions you come up with.

Hey guys, im looking into trying to switch to a spin on fliter insteaf of the leaky canister style. Ive read the posts about pressure being too high in reverse. I have a mechanical oil pressure gauge and it only shows about 60lbs in reverse. The spin on adapters for our host state they will not work on autos

So does anyone have a site or part # for one the will fit an auto?

Thanks Mike
