What i find strange is that the coolant that came out when removing oil cooler was clear of any oil i know oil floats on water but i thought i still would have seen some discolo...

Yeah oil level dropping and no i dont have a oil temp gauge was thinking of bypassing the oil cooler but wasnt sure if my oil would over heat?
