I have a 76 Eldorado 500 fuel injected. Bought the car a few months ago and haven't driven it since the engine runs rough etc. am just getting into it now. The issue I am looking into now is it seems to be burning oil as there is blue smoke coming from the tailpipe while the engine is running. The car has 78,000 miles on it. I changed the plugs this past weekend but still runs rough it sounds similar to when the catalytic converter is plugged however someone before me removed that. I would really appreciate any insight as to what could cause it to burn oil besides issues with the valves etc. I am wanting to try to do the simple fixes first before I tear into the motor.
