there is a crank case half with pressure/ return ports machined in the galley that feeds the head. It was found on some early carters and dazons. the ports were intended for the addition of an oil cooler. the tia scooter guys use these case half's for turbos. I don't know anymore who supplies these cases but they are out there. I recall posting some pics of this case half some time ago. do a search in my posts for oil coolers.
