Al,
I have heard two different theories on oil cooer/filter = locations. Some=20 propose going through the cooler first, to make sure nothing in the = cooler=20 comes into the engine, and others (you included) advocate filtering = before the=20 cooler. I am confused -- Tracy/Ed, what did you do? Others?
