I've been reading here about Dan's blown engines (sorry your having this challenge again), and the roll of the cooler, filter, bypass valve, and whatever else comes to our mind as to the cause.

We have established that the oil flows from oil pan to pump, to oil cooler, to oil filter/bypass valve, to internal moving parts.

I read that the bypass valve requires 5 to 6 lbs to open. The oil pump will put out 40 to 80 lbs (depending on relief valve)with cold oil.

With that established, the question I'm thinking is, does the filter media create more or less back pressure then required to open the bypass?
If it's less then all the oil is filtered, if more then only a percentage is filtered (and some impurities can sneak through), then we need to look at increasing the filtering media area to decrease the back pressure, by bigger filter, multiple filters, increase bypass pressure or block bypass, or ?.

My thoughts on filters for now.
