I’m in the process of installing my new oil pump gear set. I disassembled the oil pump pressure relief valve assembly for cleaning.

The shown parts below in picture one are the snap ring, cup with o-ring,spring and relief valve. Visible when the oil pump gears are removed. Got all that for sure.

Now, on the the other side of the timing cover, by the oil pressure switch, is another snap ring, cap with o-ring and spring. BUT no relief valve under the spring.

Am I missing something? Should there be oil pressure relief valve under both spring assemblies?
