I had white-blue smoke coming from my exhaust at idle and under acceleration after I changed my oil. After I had only a quart on there, it stopped. What would cause my car to blow smoke with a little oil, and be fine when the oil is full? I checked the timing, idle plugs, head gasket, coolant, and dizzy with no uck. It's a 1990 Civic D15B2. 193,200 miles and countin baby!
