Idaho, is it a sweet smell, or more like burning oil. Does the engine have to be hot and ran for some time...is it worse after driving hard?
The vent on the right side (I call it my garage heater
) comes right off the engine. I'm not an expert on Porsches but I know the pipe to put oil in the car crosses right over the engine, it is the only thing that has leaked on my car. The other thing is antifreeze has a sweet smell. I also find that these older cars the catalytic converters sometimes give off an odor. Anyway maybe the experts will chime in. Have you looked at the engines on any of the ones you test drove to see if they were a mess or not?
