It doesn't seem to leaking into the expansion tank?
What other parts should I replace at the same time?
also,the left head was rebuilt due to cam chain breakage and valve breakage only on the left side.I believe that only the left side was worked on.Should I rebuild the RIGHT head at this time?
what do I need other than a head gasket seal KIT?

Thank you!!
