I recently purchased a 2011 gg 280 and was running it yesterday and it started smoking more then normal with a odd smell. My first though was the head o rings. But then I saw my tranny oil was milky. The water pump shaft had some play which would cause antifreeze to get into the oil but could that get into they cyclinder? Or could my o ring have been bad and it put to much pressure to the water pump seal and ruin that also? Any help would be appreciated thanks
