Oil cooler ?? Gear ratio ??

Thx,

What exactly do you want to compare?

The valve cover based cooler systems are really nice in regards to simplicity. The lines are up high and generally hidden up under the tank to the cooler and back. Since they cool the oil flow going to the head it is pressurized instead of suction based. If there was one real drawback to this style it would be that it makes doing valve checks more complicated since you have to disconnect the lines, or leave them long enough that the valve cover and be moved out of the way.

As far as effectiveness goes, it's hard to really argue against either as they are both cooling the oil flow. One could argue that the sump system is more efficient in regards to keeping the entire system cool since it is distributed evenly, but on an aircooled motor the cylinder head is the most crucial part to be cooled, and the valve cover based system doesn't get any more direct than that, which would also still keep the rest of the system's oil at a more stable temp.
