Thanks for the link. I've been trying to convice myself with similar arguments that other people have mounted it upside down and have had no problems with their oil pressure; I think there was even a picture of the GST/Hankook 2door subaru Global time attack podium winning car in Modified mag with its front bumper off, showing a cooler of something, mounted upsidedown. *edit , found a pic*

Maybe it depends on the engine itself? (oil squirters, oil passages?)

I dont think I purged it correctly, I just filled the oil cooler with oil rightside up, attached both hoses to it, attached one end to the thermostat sandwich and then poured oil into the other side of the hose and attached that side.Then I started the engine and let it warm up, listened for the thermostat to open and when both hoses and cooler were warm to the touch, I took it out for a drive.

Could the thermostat's positioning (ports facing the firewall instead pf the ground) have anything to do with the decrease in oil pressure?
