I'v got a leak

Rode my cx into town the other day to grab some drinks at the grocery store and on the way there i thought i smelled some coolant but didn't think much of it. Got home and noticed my temp gauge was up higher than normal and when I pulled into the barn there was steam coming form the upper left of the engine. So the initial inspection lead me to believe it was the upper radiator hose. After removing the upper radiator hose and its coiled metal shield i decided to replace the old hose clamps and reinstall to make sure it wasn't just a leak at the clamp.



With the new clamps the bike is still leaking and its not at the upper radiator hose.



This leads me to believe that the leak is coming form either the thermostat housing or the pipe coming off the housing going to the block.



What else could be leaking in that area? No coolant is leaking towards the right side of the bike just the left.

I've been on this forum for several year now and every now and then, people get bad head gaskets. Usually the bad ones are some no brand Chinese knock off but you never know.



I'll conjecture that the milky stuff inside your valve covers is the result of coolant leaking, not any theoretical condensation. I'd take it all apart, clean the mating surfaces and then use Permatex head gasket sealant in addition to the head gasket. Torque it all down properly.
