Right; I wasn't really thinking and was making like the bypass detoured it to the sump.FYI, the flowrate remains the same irregardless of bypass valve...
Maybe you can answer this question -- looking at schematics, it looks like oil goes from the sump, through the sump filter, through the pump, through the side filter, in that order. I see lots of pictures of debris in the side filter with no mention of a hole in the sump filter. How do you explain that? Is the side filter that much finer than the sump filter?
