    Ok the front one I left stock and the rear is the one I blocked and
 replaced with an external valve, when I get to the airport I will
 shoot a photo of it.

I have a picture but I can always use another one. Here is the one I have.
I am not sure how this works however. What are we looking at here?

   It just bleeds oil from the oil inlet from the cooler and returns
it to the oil pan, the larger line on the return side is the main
return and the smaller one is just a bleed to stop oil pressure form
building up behind the spring.
