If yes take it apart again and make sure you reassembled it correctly.

Took apart again. Everything seemed in order... cleaned around new o rings. When cold still had difficulty holding pressure. If I pumped up to 4psi I could hear a high pitched squeal coming from around bleed valve housing.
Nevertheless I started the car and once it began to warm up, I was able to pump pressure tester to 5-7lbs and it would hold pressure. As engine warmed up pressure increased as well.
Wondering if I’ve finally seated the bleed valve correctly.
Popping up tab on bleed valve reveals a burbling sound which goes away with tab down. System still holds pressure and does not leak out overflow valve.
Despite having an .04 cap I think that is now the culprit.
Off to dealer to grab new cap. Fingers crossed!
Many thanks for all of the great suggestions.
