Question about Greddy oil cooler
 

Could some one please help with my understanding of Greddy's oil cooler adapter?
Picture 1. It look like there is one inlet and one outlet.(And there is a choice of which inlet and outlet you use). So oil goes to the cooler then through to the engine in the same path/oil passages as original.
Picture 2. This is the FR-S/BRZ/86 Oil Block Set (Greddy part number 12002802). The way I am seeing the picture there is only one major outlet. (Red arrow). Those 1/8PT threads are for sensors; too small I think for oil return.
How does the oil get back to the engine?

Thanks.

picture 2 is an oil sensor/sender block, it's not for an oil cooler.

It is suggested here http://www.ft86club.com/forums/showt...ddy+oil+cooler that you will need that spacer kit.

Ah. My brain misinterpreted. Greddy have a pic of the spacer AND sender unit adapter. So I'm guessing my 1st pic will fit on top of the spacer.
(I wish they would reply to my email.I had asked them this very question to no avail).
