Glad you back up and running! :thumbsup:Just curious. . .how can you tell if the valves aren't moving? I bought a 445 yesterday and it makes lots of white smoke on start up and continues to smoke once running (I knew this when I bought it though). The smoking is intermittent and I noticed it was its worst when going up or down the ramp on my trailer. Engine runs flawlessly, very strong, easy to start, etc. I'm starting to figure what is causing the smoke and how much its going to take to get her up to par. At this point I'm thinking head gasket, just hoping its not more serious than that.
