What you see is out of the ordinary. I think you need to do some more fact finding to decide what is causing it.

Thank you Sclor - oddly I never see any Blue smoke to indicate the oil is being burned....I have a mechanic who knows these engines, and I will have to get him to check these ideas you have I guess. The truck runs like a top so no complaints and its the most dependable truck I have ever owned - if there was ever a perfect running engine this 305 E seems to be it, but it might be about to come apart and I just don't know it too
