I'm not sure why, but my dipstick started blowing a fine mist of oil out. I noticed it after I got back home with the boat and saw that there was a greasy film all over the transom on that side. Definitely didn't come from the headers or the breather valves on the valve covers. It is a 455 olds with a 10qt Moroso pan on it. If anyone knows why, I'd be much appreciative. Thanks!
