[QUOTE="mech 1 twa, post: 1345575, member: 551"] I've read most of this. Everything you describe points to bad head gasket. Excessive pressure pushing coolant into overflow tank, combustion pressure. Internal pressure into cooling system, causes air pockets hot spots as air is mixed in. Head gasket can leak but have no coolant going into oil or cylinders. Dealer messed something up. Over heated engine, then added some kind of stop leak. Difference in coolant colors you described. I've seen this problem before on a few cars nothing different with a motorcycle engine compared to car. Replaced my wife's head gasket on her Honda Civic same issues. Her car never over heated caught it early. 25 plus years Honda auto Tech. Just my 2 cents. [/QUOTE]
