I have a 230SL with a 280 engine in it. When it was installed, they used the 230SL filter housing with no oil cooler hose take offs. I know the 280 should have an oil cooler so would like to add one. I've found a number of air/oil after market coolers that I could make work. Has anyone found another place to take off and return oil? Or does anyone have a 250 or 280 filter housing with oil take off and return they would like to sell?
