At the risk revealing my ignorance, why would a bypass valve be important? If
I understand correctly (and since there are no electrons involved, there is a
good chance I don't), the purpose of the bypass valve is to allow oil to
bypass a clogged filter. That is probably a good idea for the great un-washed,
but is there any one on this list that would let a filter go un-changed to the
point that it becomes clogged? Or does the bypass serve another function as
well?
