Hi, those are two different gaskets. Is the rear valve different from the front one?The best solution, in my opinion is to replace the gaskets.

You can alternatively clean and dry the existing gaskets well, and use Hondabond as a gasket maker to reseal the area.... but I'd personally order the new gaskets. The reason that many videos or even Honda dealers used the Hondabond, is because these gaskets were not made separately and required replacing the entire spool valve assembly. Now the need for new gaskets has been filled by the aftermarket.
