NOT a Ford guy but!!!!

Oh yea, forgot about the oil cooler. There are two types.

There is one the has an external cooler like an auto cooler than plumbs into the 90deg oil filter adapter. Basically and air to oil cooler.

The other has a "box" built into the adapter that uses the lower radiator hose to cool the oil. These are known to rot and get coolant into the oil or vise verse. I have one of these and didn't use it.
