Reading the info on this link is scary. It sounds like the oil will ALWAYS go through the relief and never be filtered or cooled. If this is the case, what's the solution???

This is what the one picture says....
1) By-pass valve - According to MM X-7525 the valve opens at 5.3 to 6.3 psi and returns uncooled and unfiltered oil to engine block
2) Oil cooler adapter and oil filter attachment fitting - returns cooled and filtered oil to engine.
3) Inlet from engine oil pump
When the by-pass opens the oil flow goes directly from the inlet port 3) to the by-pass valve 1) because it is the path of the least resistance (shown by the red arrow). The path through the oil cooler adapter, lines, oil cooler; and oil filter has more resistance.
