This what I installed on my track car. I used two 964 coolers, that were ultrasonically cleaned, but I have trust issues.
Along with the two coolers there are oil lines to and from the motor, 3 gallon tank, thermostat, coolers and all the fittings to make it work. All was carefully cleaned and inspected but I wanted to be sure nothing got back into the motor so I added an O-berg sandwich filter in line on the tank to motor line.
It is low resistance and I bet a method for adding one in line between the tank and motor could be built for stock applications. Won't help much with a spun bearing, not much will other than a 100% non bypass filter,but might give some peace of mind that the oil that has wandered far from home will return clean.
Even after super cleaning everything oil related the O-berg trapped an alarming amount of junk like a nice nasty saw chip from the tank that hid from inspection and some little bits that I think came from the coolers.
