I have a 85 280ce 5spd and I just blew the head gasket. I need to know what model number engine I have. The only numbers on the engine I could find d are r110 016 19 01 also there's a 17 after a Mercedes symbol. I did some digging and think it's a m110.988 but not sure. Will a head gasket made for a 81 m110988 fit my 85? Again please help I put 100miles on after 20yrs of it sitting and now it's back in the garage.
