I have a 1993 Tracer LTS with the better part of 300k on the engine. When the temperature outside is 65 degrees or cooler, the engine blows blue smoke. If it is a warmer day, the engine blows zero smoke at start up. In fact, the hotter it is outside, the better this car runs. Any ideas on how to resolve the smoke issue would be greatly appreciated. This car is a daily driver with routine maintenance performed.
