Daihatsu burning oil - Help!
I have a mower with a Briggs Vanguard Daihatsu that is eating oil. I'm estimating at least a qt every 50 hours. The motor is a model DM950D with 314 hrs on it. There are no leaks on the floor and the water is fine. From a cold start it blows a lot of white/gray smoke then quits smoking. It doesn't smoke when running or from a hot start. A friend says this is a sign a bad valve seals. Is replacing the seals a hard job? At 314 hrs I wouldn't think I should be having this type of problem but I did buy it used so who knows. I am hoping to get opinions on his diagnosis or suggestions as to what else it could be. Any help would be great.
PS
I made this post on a tractor forum and the two comments I got so far is this engine is junk and not to bother fixing it. That's not what I have read about it. Supposedly it's a good motor if not overheated. Anyone know how good/bad they are?
