I have a 1990 grandam that needs a new oil seperator(black plastic box above intake),when I went to the dealer they asked me if it has a heated vent system or the non heated system.My question is how can you tell which one i have.Thanks
Take a look at the big hose on the right side of the separator. If the hose is in two sections with a black plastic insert joining them and the insert has an electrical connector on it there is a heater inside the hose.
