I don't know what to think. I covered the breather port for over 20 seconds and the engine didn't die. It didn't even skip a beat. When I uncovered the port, there was a healthy puff.

FWIW, engine mileage unknown but I have reason to believe it's just under 150K since replaced or rebuilt, Castrol 20W50, I haven't had it long enough to for my 50/50 city highway to sawy whatever the average was before I got the car, I haven't had it long enough to measure oil consumption either. It's the smoothest and quietest 617 I've been in, it starts right up and doesn't smoke that I've seen... and I've looked.

BTW, this was on the SD.

Someone want to tell me what all this means? Could it be a problem with the rack?

Thanks,
Sixto
