I just checked the fluids and oil is maybe down just a little water looked about the same but I will say it is hard to tell because I usually don't keep any water in the overflow. But water in radiator looks the same. I put some in overflow tank and can monitor that. I was wondering could this be oil and moisture built up in exhaust from 327 that is now getting burned out although we have put on 800 miles should be cleaned out. Also on cold startup it really doesn't seem to smoke I just started in garage with door shut and really couldn't notice any smoke. But when stopped a short time and hot it seems to puff some smoke, does this say anything to you pro's?
