One of the more frustrating parts that leak oil on the 911 are the oil return tubes. Years of heating and cooling, and expansion and contraction, can leave the rubber seals brittle and worn out. It is very common for them to leak oil right onto the heat exchangers, which results in both the car smoking when it’s started, and also can result in smoke entering the passenger compartment through the heater system. The good news is that the tubes can easily be replaced with expandable replacements that don’t require the removal of the engine.
