After having an overheating problem at the end of my first ride, I found the fan was not turning on. I ended up thinking the relay was out (fan ran when jumped, fuse ok, Procom ecu). Well I come to notice the overflow bottle is empty. Check the radiator, empty too. Fill the radiator/overflow, fan works fine. It has no leaks and runs and starts great, thinking head gasket. Drained the oil, extremely milky and appears to be more than a quart. Is this accurate for a blown head gasket? What other things should I look out for?
