Just purchased 84 280 sel and need a couple of things for the car. It has 65,000 original miles and the valve cover is leaking along with the lower gasket. It is not the headgasket but a lower valve cover gasket. Need to know if any year had the same engine american version.

As you probably already know this is a grey market vehicle meaning made for europe but imported to the states. Also looks like the o2 sensor is bad. Question is in europe do they have O2 sensors?? Wiring does not look oem? Any comments would be greatly appreciated.
