When my YM1601 gets good & warmed up, it starts putting a little steam out the hose that comes off the top of the valve cover (guessing this is its PCV valve). Is this a bad head gasket issue? Or is something else going on?
I recently replaced radiator cap, some cooling hoses, and clamps to make sure my loss of coolant was not from those sources. I've also added some of that copper / sodium silicate block sealer. Radiator now holds a pretty good pressure after cool down (makes a pop when cap removed). So maybe with more pressure, more leaks are showing up.
There was one external head gasket leak on the intake side that reopened and temp immediately jumped when it did. This leak then resealed when added more coolant.
Thanks
