Oil cooler -> low oil pressure

[Rascal21]

Some 4A`s have oil pressure switches instead of oil pressure sensors, the only difference is that the switch activates a light for low oil pressure, and the pressure sensor gives feedback to a normal gauge.
They sit on the same place, a little forward between #1 exhaust tube and oil filter, if you have a hole there, and nothing screwed in, then you have a problem..

Standard 4AGE oil cooling setup, as mentioned above here, is only partial flow, a complete setup with sandwich, filter-reloc with 2 intake and 2 outtakes (For oil cooler and sandwich) gives you full flow.
With this you can also use a thermostat (I know some Mocal sets have that) which lets oil through to the oil filter only when necessary.

IMHO oil pressure is more important than oil temperature, optimal pressure is somewhere along 5,5-7 bars, 2,5 bar of oil pressure is going to kill your engine way faster than some 120-130 celcius degrees oil temperature.

Because I couldnt afford a proper cooler setup, and I didnt want a half-arsed solution, I went for the short 4A oil filter bolt/union, and installed the filter straight onto the block, oil temps might get a bit high, but it beats low oil pressure..
