I have a B7500 with only about 35 hours on it. Recently, in colder weather start-ups, I notice a hissing noise when I first start-up the tractor. After it warms up, it goes away. It sounds like its a blow-off somewhere around the engine, but I can't define it. I am used to a waste gate opening on my Powerstroke when it's cold, but is there such a thing on a little Kubota? Hiss Hiss Hiss. /w3tcompact/icons/laugh.gif
